batch script to extract lines between two specified lines - batch-file

I have a text file and would like to extract all the lines between two specified lines using windows batch scripting.
Line1: !FILE_FORMAT=ADS
Line2: !VERSION=1.0
.
.
LineX: 'Parent|Child|IsPrimary|**** (the line starts with ' and is long)
.
.
LineY: !PropertyArray=Cost Center (The lines starts with !)
.
.
LineZ.
I want to extract all the lines between LineX and LineY and output it to another file.
The below code finds the starting line correctly. But it just deletes the line(Line Y) where I want the stop the script and outputs the rest of the file.
The output is from Line X to Line Z without Line Y.
#for /f "tokens=1 delims=[]" %%a in ('find /n "'Parent|Child"^<D:\DEV\Test\Cost_Center.txt') do #(
more +%%a D:\DEV\Test\Cost_Center.txt |find /v "!PropertyArray=Cost Center" || goto :eof)>D:\DEV\Test\Cost_Center_Out.txt

#ECHO OFF
SETLOCAL
SET "sourcedir=c:\sourcedir"
SET "destdir=c:\destdir"
for /f "tokens=1 delims=[]" %%a in ('find /n "'Parent|Child"^<"%sourcedir%\Cost_Center.txt" ') do set /a start=%%a
for /f "tokens=1 delims=[]" %%a in ('find /n "!PropertyArray=Cost Center"^<"%sourcedir%\Cost_Center.txt" ') do set /a end=%%a
(
for /f "tokens=1* delims=[]" %%a in ('find /n /v ""^<"%sourcedir%\Cost_Center.txt" ') do (
IF %%a geq %start% IF %%a leq %end% ECHO(%%b
)
)>"%destdir%\newfile.txt"
GOTO :EOF
Using the approach that you're comfortable with - I've changed the source and destination directories/filenames to suit my system. Not sure whether you want to include your two target lines - it's just a matter of changing geq to gtr and/or leq to lss depending on which, if any, you want to exclude.
Might have been easier if you'd included some sample data...
edit 20130807T0207Z ECHO becomes ECHO( to cope with empty lines.

you can do this with sed for Windows:
sed "/'Parent|Child|IsPrimary|/,/!PropertyArray=Cost Center/!d" file1 > file2

This uses a helper batch file called findrepl.bat from - http://www.dostips.com/forum/viewtopic.php?f=3&t=4697
type file.txt |findrepl "^'Parent\|Child\|IsPrimary\|" /e:"^!PropertyArray=Cost" |findrepl /v "^!PropertyArray=Cost">newfile.txt
The ^ at the start of the terms means it starts in column one. The \| you see is the escaping of the | character.

Delete especific lines numbers with batch file

I'm trying to make a script that delete especifics lines of a .txt file by it number. I alreay got it:
#echo off
for /f "skip=1delims=*" %%a in (test.txt) do (
echo %%a >>newfile.txt
) >nul
It works fine and delete the line number '1'. But if i put more lines to delete, it doesn't work, see below:
#echo off
for /f "skip=1,5,8) delims=*" %%a in (test.txt) do (
echo %%a >>newfile.txt
) >nul
What is worong?
as already noted in the comments, skip doesn't help. Instead add line numbers (with find /v /n "") and output the original line (token2) without the line number, if the line number (token1) is not in the list:
#echo off
(for /f "tokens=1,* delims=[]" %%a in ('type test.txt^|find /v /n ""') do (
echo/%%a|findstr /x "1 5 8" >nul || echo/%%b
))>newfile.txt
(findstr switch x is important to compare the whole number, so 2018 isn't found with findstr "1")
|| works as "if previous command (findstr) failed, then"
As suggested findstr and for /f are the tools to use.
I add in conditional execution on fail || or success &&
if findstr does not detect the current line number (produced by the /n option) enclosed in commas in the echoed skip variable the Line is written to newfile.
:: Q:\Test\2018\06\09\SO_50777309.cmd
#echo off
:: generate test.txt with Line1..10
(for /l %%A in (1,1,10) do #Echo=Line%%A) >test.txt
Set "skip=,1,5,8,"
(for /f "tokens=1,*delims=:" %%a in (' findstr /n "^" ^<test.txt'
) do Echo=%skip%|findstr ",%%a," 2>&1>NUL ||Echo=%%b
)>newfile.txt
type newfile.txt
Sample output
Line2
Line3
Line4
Line6
Line7
Line9
Line10
Here is a variant without a pipe (|), which should be faster. Also lines with leading colons (:) or brackets ([/]) should be treated correctly here:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "_FILE=test.txt"
set "_FNEW=newfile.txt"
set "_SKIP=,1,5,8,"
> "%_FNEW%" (
for /F "delims=" %%L in ('findstr /N "^" "%_FILE%"') do (
set "LINE=%%L"
for /F "delims=:" %%K in ("%%L") do (
setlocal EnableDelayedExpansion
if "!_SKIP!"=="!_SKIP:,%%K,=,!" (
echo(!LINE:*:=!
)
endlocal
)
)
)
endlocal
exit /B

Batch script to read a specific line from a log file

I am trying to write a batch script that reads 18th line from a .log file and outputs the same. The .log file name varies each time. abc_XXXX.log where xxxx are process IDs. Below is the code I am trying to run to achieve this.
:Test1
set "xprvar=" for /F "skip=17 delims=" %%p in (abc*.log) do (echo %%p& goto
break)
:break
pause
goto END
set var=anyCommand doesn't work. It just sets the var to the literal string.
The usage of afor /f is the right way, just the variable assignment works different:
for /F "skip=17 delims=" %%p in ('dir /b abc*.log') do ( set "xprvar=%%p"& goto break )
There is also an option using FindStr
#Echo Off
For /F "Tokens=1-2* Delims=:" %%A In ('FindStr/N "^" "abc_*.log" 2^>Nul'
) Do If %%B Equ 18 Echo %%A:%%C
Pause
The above example Echoes the <filename>:<18th line content>, but there's no reason in the appropriate situation why you couldn't change that to read:
#Echo Off
For /F "Tokens=1-2* Delims=:" %%A In ('FindStr/N "^" "abc_*.log" 2^>Nul'
) Do If %%B Equ 18 Set "xprvar=%%C"
If there is more than one matching filename in the directory, the variable would be set to the content in the last file parsed.
#ECHO Off
SETLOCAL
FOR %%f IN (abc*.log) DO (
SET "reported="
FOR /f "skip=17delims=" %%p IN (%%f) DO IF NOT DEFINED reported (
ECHO %%p
SET "reported=Y"
)
)
Assign each filename in turn to %%f.
For each filename found, clear the reported flag then read the file, skipping the first 17 lines. echo the 18th line and set the reported flag so that the remainder of the lines are not echoed.

Batch script to extract same line from each log file

I have a number of text files that are always the same number of lines - 42 and always the same type of information on each line. Also each line starts with a header.
What I would like is a batch script to keep line 30 of the text file remove the others and save the file.
I have tried to look find the line based on the information between two line. In this case the heading on line 30 (Job Notes) and the heading on line 31 (Job Number) and then write the information to a new file.
Line 30 begins with
Job Notes= (information specifically about the job)
Line 31 begins with
Job Number=
This is the code I used (which i found elsewhere on this site) and i am getting no output at all. Have tried other ways as well so don't really have to use this method if you can see a better one, basically i just want line 30 to be the only information in the file.
#ECHO OFF
SETLOCAL
SET "sourcedir=C\Batch"
SET "destdir=C:\Batch\Extract"
for /f "tokens=1 delims=[]" %%a in ('find /n "Job Notes"^<"%sourcedir%\7099.txt" ') do set /a start=%%a
for /f "tokens=1 delims=[]" %%a in ('find /n "Job Number"^<"%sourcedir%\7099.txt" ') do set /a end=%%a
(
for /f "tokens=1* delims=[]" %%a in ('find /n /v ""^<"%sourcedir%\00007099.txt" ') do (
IF %%a geq %start% IF %%a leq %end% ECHO(%%b
)
)>"%destdir%\newfile.txt"
GOTO :EOF
Any help would be greatly appreciated.

Option 1, using findstr string numeration
for %%a in (*.log) do (
for /f "tokens=1,* delims=:" %%b in (
'findstr /n "^" "%%a" ^| findstr /b "30:"'
) do (
echo(%%c>"%%a"
)
)
Option 2, using for command skip lines
setlocal disabledelayedexpansion
for %%a in (*.log) do (
set "line="
for /f "usebackq skip=29 delims=" %%b in ("%%a") do if not defined line set "line=%%b"
setlocal enabledelayedexpansion
echo(!line!>"%%a"
endlocal
)
You want you the /N flag with FINDSTR:
FINDSTR /N /R ".*" *.txt | FINDSTR /R "\<30:" > out.txt
Explanation:
FINDSTR /N /R ".*" *.txt
finds every line (".*" with the regex flag /R) in every text file (*.txt) and appends its line number to the front (/N). This is then piped to
FINDSTR /R "\<30:"
which only grabs lines starting with (that's the \< bit) 30:.
#ECHO OFF
SETLOCAL
SET "sourcedir=C\Batch"
SET "destdir=C:\Batch\Extract"
for /f "skip=29tokens=1* delims==" %%a in ('type "%sourcedir%\7099.txt" ') do ECHO(%%b >"%destdir%\newfile.txt"&goto nextstep
:nextstep
GOTO :EOF
should do the job, finding line 30 (by skipping 29) then tokenising on the separating = and having output exactly one, going to the next step in your batch.
Having said that, however - you do realise that you are setting start and end using 7099.txt and then picking the data from 00007099.txt don't you? Does 00007099.txt exist?
And c:\batch seems a mighty strange place to store data files to me. Personally, I'd put batch files there (and include c:\batch into your PATH) but it's your system...

Bat file that takes specific variables on specific lines from texts

I need to create a batch file that searches through 2 texts. Captures a line of text in a variable (that contains at least one of 3 strings, but doesn't contain forth string) and its line number.
Searches through the second text and captures in another variable the line of text that exists on the line-number of the first variable.
I need to use the two lines-of-text (variable) after that as well.
I kind of managed through the first text reading, but not sure what I'm doing wrong in the second one:
#echo off
set "found="
for /f "tokens=1,* delims=[]" %%a in (' find /n /v "" ^< "%LocalDir%\list.txt" ') do (
echo "%%b"|findstr /i /c:"one two small" /c:"one two birds" /c:"one two strings" >nul && set found=1
if defined found echo "%%b"|findstr /v /c:"one two small red apples" >nul || set "found="
if defined found (
echo %%a found
#echo off & setLocal EnableDelayedExpansion
set var=%%b
set Line_num=%%a
endlocal
) else (
echo %%a NOT FOUND
)
set "found="
)
REM part2--------------------
for /f "delims=" %%d in (list1.txt) do (
set FullVersion=%%d
#echo off & setLocal EnableDelayedExpansion
for /f "tokens=1* delims=" %%e in ("%%d") do (
if !Line_num!==%%e
set var2=!FullVersion!
echo !var2!
)
)
endlocal
echo %var%
echo %var2%
Any help will be appreciated.
here is what I end up with as solution:
for /f "tokens=1,* delims=[]" %%a in (' find /n /v "" ^< "%LocalDir%\software_list.txt" ') do (
echo "%%b"|findstr /i /c:"Micro Focus Enterprise " /c:"Micro Focus Visual" /c:"Micro Focus COBOL" >nul && set found=1
if defined found echo "%%b"|findstr /v /c:"Micro Focus Enterprise Server for .NET" >nul || set "found="
if defined found (set LineNumber=%%a&set ProductName=%%b)
REM else (echo Main Micro Focus product NOT FOUND. Nothing to do. Exit.&exit /b)
set "found="
)
find "2." temp1.txt > temp3.txt
for /f "tokens=2,3 delims==" %%c in (temp3.txt) do (echo %%c >> %LocalDir%\software_list1.txt)
for /f "tokens=1*delims=[]" %%a in (' find /n /v "" ^< "software_list1.txt" ') do IF %%a==%LineNumber% SET ProductVersion=%%b
REM ECHO %LineNumber%
REM ECHO %ProductName%
REM ECHO %ProductVersion%
set ProductName=%ProductName:"=%
set ProductName=%ProductName: =%
set ProductVersion=%ProductVersion:"=%
set ProductVersion=%ProductVersion: =%
set out_file_name=%ProductName%_%ProductVersion%_%COMPUTER_NAME%
REM echo %out_file_name:"=%
Thanks a lot to everyone.
I see some problems in your code:
This block makes no sense, as it set variables in a new setlocal context and after the endlocal the variables are lost.
#echo off & setLocal EnableDelayedExpansion
set var=%%b
set Line_num=%%a
endlocal
In the second block you open a setlocal context for each iteration, that will result in a overflow error.
And the endlocal after the Part2 seems also to be contraproductive.
The line if !Line_num!==%%e creates always a syntax error
Btw. Why do you use #echo off inside your code? The frist one at the batch start should be enough.
You should only use one setlocal EnableDelayedExpansion at the beginning of the script.
You should only use DelayedExpansion toggling, if you have problems with exclamation marks.
You could use some echo's to see what happens, like
for /f "tokens=1* delims=" %%e in ("%%d") do (
echo Compare: !Line_num!==%%e
if !Line_num!==%%e set var2=!FullVersion!
echo !var2!
)
#echo off
set "found="
for /f "tokens=1*delims=[]" %%a in (
' find /n /v "one two small red apples" ^< "%LocalDir%\list.txt" ') do (
echo "%%b"|findstr /i /c:"one two small" /c:"one two birds" /c:"one two strings" >NUL
IF NOT ERRORLEVEL 1 SET lnbr=%%a&SET ltext=%%b
)
for /f "tokens=1*delims=[]" %%a in (' find /n /v "" ^< "list1.txt" ') do IF %%a==%lnbr% SET L1txt=%%b
ECHO(line number %lnbr%
ECHO(from LIST %ltext%
ECHO(from LIST1 %L1txt%
This should do what you want - if I understand correctly. Much better to show your data and an example of required output. Trying to fix code that DOESN'T do something undefined is frustrating.

DOS batch FOR loop with FIND.exe is stripping out blank lines?

This DOS batch script is stripping out the blank lines and not showing the blank lines in the file even though I am using the TYPE.exe command to convert the file to make sure the file is ASCII so that the FIND command is compatible with the file. Can anyone tell me how to make this script include blank lines?
#ECHO off
FOR /F "USEBACKQ tokens=*" %%A IN (`TYPE.exe "build.properties" ^| FIND.exe /V ""`) DO (
ECHO --%%A--
)
pause
That is the designed behavior of FOR /F - it never returns blank lines. The work around is to use FIND or FINDSTR to prefix the line with the line number. If you can guarantee no lines start with the line number delimiter, then you simply set the appropriate delimiter and keep tokens 1* but use only the 2nd token.
::preserve blank lines using FIND, assume no line starts with ]
::long lines are truncated
for /f "tokens=1* delims=]" %%A in ('type "file.txt" ^| find /n /v ""') do echo %%B
::preserve blank lines using FINDSTR, assume no line starts with :
::long lines > 8191 bytes are lost
for /f "tokens=1* delims=:" %%A in ('type "file.txt" ^| findstr /n "^"') do echo %%B
::FINDSTR variant that preserves long lines
type "file.txt" > "file.txt.tmp"
for /f "tokens=1* delims=:" %%A in ('findstr /n "^" "file.txt.tmp"') do echo %%B
del "file.txt.tmp"
I prefer FINDSTR - it is more reliable. For example, FIND can truncate long lines - FINDSTR does not as long as it reads directly from a file. FINDSTR does drop long lines when reading from stdin via pipe or redirection.
If the file may contain lines that start with the delimiter, then you need to preserve the entire line with the line number prefix, and then use search and replace to remove the line prefix. You probably want delayed expansion off when transferring the %%A to an environment variable, otherwise any ! will be corrupted. But later within the loop you need delayed expansion to do the search and replace.
::preserve blank lines using FIND, even if a line may start with ]
::long lines are truncated
for /f "delims=" %%A in ('type "file.txt" ^| find /n /v ""') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*]=!"
echo(!ln!
endlocal
)
::preserve blank lines using FINDSTR, even if a line may start with :
::long lines >8191 bytes are truncated
for /f "delims=*" %%A in ('type "file.txt" ^| findstr /n "^"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*:=!"
echo(!ln!
endlocal
)
::FINDSTR variant that preserves long lines
type "file.txt" >"file.txt.tmp"
for /f "delims=*" %%A in ('findstr /n "^" "file.txt.tmp"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*:=!"
echo(!ln!
endlocal
)
del "file.txt.tmp"
If you don't need to worry about converting the file to ASCII, then it is more efficient to drop the pipe and let FIND or FINDSTR open the file specified as an argument, or via redirection.
There is another work around that completely bypasses FOR /F during the read process. It looks odd, but it is more efficient. There are no restrictions with using delayed expansion, but unfortunately it has other limitations.
1) lines must be terminated by <CR><LF> (this will not be a problem if you do the TYPE file conversion)
2) lines must be <= 1021 bytes long (disregarding the <CR><LF>)
3) any trailing control characters are stripped from each line.
4) it must read from a file - you can't use a pipe. So in your case you will need to use a temp file to do your to ASCII conversion.
setlocal enableDelayedExpansion
type "file.txt">"file.txt.tmp"
for /f %%N in ('find /c /v "" ^<"file.txt.tmp"') do set cnt=%%N
<"file.txt.tmp" (
for /l %%N in (1 1 %cnt%) do(
set "ln="
set /p "ln="
echo(!ln!
)
)
del "file.txt.tmp"
I wrote a very simple program that may serve as replacement for FIND and FINDSTR commands when they are used for this purpose. My program is called PIPE.COM and it just insert a blank space in empty lines, so all the lines may be directly processed by FOR command with no further adjustments (as long as the inserted space don't cares). Here it is:
#ECHO off
if not exist pipe.com call :DefinePipe
FOR /F "USEBACKQ delims=" %%A IN (`pipe ^< "build.properties"`) DO (
ECHO(--%%A--
)
pause
goto :EOF
:DefinePipe
setlocal DisableDelayedExpansion
set pipe=´)€ì!Í!ŠÐŠà€Ä!€ü.t2€ü+u!:æu8²A€ê!´#€ì!Í!².€ê!´#€ì!Í!²+€ê!´#€ì!Í!Šò€Æ!´,€ì!Í!"Àu°´LÍ!ëÒ
setlocal EnableDelayedExpansion
echo !pipe!>pipe.com
exit /B
EDIT: Addendum as answer to new comment
The code at :DefinePipe subroutine create a 88 bytes program called pipe.com, that basically do a process equivalent to this pseudo-Batch code:
set "space= "
set line=
:nextChar
rem Read just ONE character
set /PC char=
if %char% neq %NewLine% (
rem Join new char to current line
set line=%line%%char%
) else (
rem End of line detected
if defined line (
rem Show current line
echo %line%
set line=
) else (
rem Empty line: change it by one space
echo %space%
)
)
goto nextChar
This way, empty lines in the input file are changed by lines with one space, so FOR /F command not longer omit they. This works "as long as the inserted space don't cares" as I said in my answer.
Note that the pipe.com program does not work in 64-bits Windows versions.

Output lines including blank lines
Here's a method I developed for my own use.
Save the code as a batch file say, SHOWALL.BAT and pass the source file as a command line parameter.
Output can be redirected or piped.
#echo off
for /f "tokens=1,* delims=]" %%a in ('find /n /v "" ^< "%~1"') do echo.%%ba
exit /b
EXAMPLES:
showall source.txt
showall source.txt >destination.txt
showall source.txt | FIND "string"
An oddity is the inclusion of the '^<' (redirection) as opposed to just doing the following:
for /f "tokens=1,* delims=]" %%a in ('find /n /v "" "%~1"') do echo.%%ba
By omitting the redirection, a leading blank line is output.
Thanks to dbenham, this works, although it is slightly different than his suggestion:
::preserve blank lines using FIND, no limitations
for /f "USEBACKQ delims=" %%A in (`type "file.properties" ^| find /V /N ""`) do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*]=!"
echo(!ln!
endlocal
)
As mentioned in this answer to the above question, it doesn't seem that lines are skipped by default using for /f in (at least) Windows XP (Community - Please update this answer by testing the below batch commands on your version & service pack of Windows).
EDIT: Per Jeb's comment below, it seems that the ping command, in at least Windows XP, is
causing for /f to produce <CR>'s instead of blank lines (If someone knows specifically why, would
appreciate it if they could update this answer or comment).
As a workaround, it seems that the second default delimited token (<space> / %%b in the example)
returns as blank, which worked for my situation of eliminating the blank lines by way of an "parent"
if conditional on the second token at the start of the for /f, like this:
for /f "tokens=1,2*" %%a in ('ping -n 1 google.com') do (
if not "x%%b"=="x" (
{do things with non-blank lines}
)
)
Using the below code:
#echo off
systeminfo | findstr /b /c:"OS Name" /c:"OS Version"
echo.&echo.
ping -n 1 google.com
echo.&echo.
for /f %%a in ('ping -n 1 google.com') do ( echo "%%a" )
echo.&echo.&echo --------------&echo.&echo.
find /?
echo.&echo.
for /f %%a in ('find /?') do ( echo "%%a" )
echo.&echo.
pause
.... the following is what I see on Windows XP, Windows 7 and Windows 2008, being the only three versions & service packs of Windows I have ready access to:
