I have a batch file that contains the code below which assigns a variable for each line in a text file.
So the text file might have:
RELEASE1
RELEASE2
RELEASE3
The batch file sets each line in the text file to var1, var2, var3 with the following code:
#echo off
setlocal ENABLEDELAYEDEXPANSION
set vidx=0
for /F "tokens=*" %%A in (sites.txt) do (
SET /A vidx=!vidx! + 1
set var!vidx!=%%A
)
I need a method to echo all the defined variables. The number of variables will always change. So it might go up to var8 or var10 etc...
I'm pretty certain a for loop would do the trick but not sure what the best approach or how to do it? I was thinking of using vidx as the number of iterations? Thanks for your help!
Very Easy
#echo off
setlocal ENABLEDELAYEDEXPANSION
set count=0
for /F "tokens=*" %%A in (sites.txt) do (
SET /A count+= 1
set var!count!=%%A
)
Rem //:Notice That %count% still stores the last variable, use this in a "for /l" loop:
for /l %%a in (1,1,%count%) do (
Rem Below line is optional and displays variable number
<nul set /p="Variable %%a: "
Echo !var%%a!
)
That should work fine as long as none of the data contains parenthesis, in which case you'll have to escape them.
Type for /? for help on this. Ask If you want an explanation.
set var|findstr /R "var[0-9]*="
May be the shortest way....

Here is my code for storing the words extracted from a log file into an array, which I want to use in the batch file later on.
cls
#echo off
set /a i=0
TIMEOUT 2
REM I want to save the words from newlog.txt into an array for later use in batch file.
SETLOCAL EnableDelayedExpansion
FOR /F "tokens=1,2,3 delims= " %%G IN (newlog.txt) DO ( set a[%i%]=%%H
& set /a i+=1 #echo !a[%i%]! )
#echo %i%
#echo a[%i%]
TIMEOUT 200
I just want to use them as global variables.
#echo off
set /a i=0
REM I want to save the words from newlog.txt into an array for later use in batch file.
SETLOCAL EnableDelayedExpansion
FOR /F "tokens=1,2,3 delims= " %%G IN (q48428047.txt) DO (
set a[!i!]=%%H&set /a i+=1)
SET a[
pause
GOTO :EOF
I used a file named q48428047.txt containing some dummy data for my testing.
Note that %i% will be replaced by the value of i *as it was when the *forwas encountered that is, 0.
Your second set within your parentheses is incorrect. It's missing the & before the #echo. Also, you appear to be attempting to increment i and then show the corresponding array entry, which makes no sense because you haven't yet stored anything in that array-entry, you've attempted to install it in the previous position. It won't work anyway, because %i% will be replaced by 0, not the varying value of i.
And whereas you may get the count-of-lines appearing on the screen, a[numlines] will not be defined.
Use pause to stop the batch for perusal. Preferably, run the command from the prompt, not by clicking.
The modified code reads each line of the file putting the first word in %%G, second in %%H and third in %%I. it then assigns %%H to a[currentlinenumber] and increments the line number in i.
The set a[ will display all environment variables whose names start with a[.
In addition to the answer already provided, if you really have a need to Echo each variable value immediately after it is Set then you would need to invoke a Call command:
#Echo Off
Rem Undefine any existing variables which begin with a[
For /F "Delims==" %%A In ('"(Set a[) 2>Nul"') Do Set "%%A="
Set "i=0"
ClS
SetLocal EnableDelayedExpansion
For /F "UseBackQ Tokens=2 Delims= " %%A In ("newlog.txt") Do (
Set "a[!i!]=%%A"
Call Echo "%%a[!i!]%%"
Set /A i+=1
)
If %i% GEq 1 Echo(&Echo %i% variables were defined&Echo(
(Set a[) 2>Nul
Timeout 200
I am currently trying to store a certain line of a text file in a batch file with this code.
for /f "tokens=* delims= " %%a in (files.txt) do (
set /a N+=1
set v[!N!]=%%a
)
set /p id="Please choose a number(1-10):"
set number=%v[id]%
echo %number%
endlocal
However instead of printing out the line it prints out
id
Could someone help with this?
Like what Aacini said I changed the line
set number=%v[id]%
by this one
set number=!v[%id%]!
and it worked
I have a million old text files that I need to convert the format on. I have been desperately trying to do this myself but I really could use help. I am trying to convert data that looks like this:
text
11111.111
22222.222
33333.333
text2
44444.444
55555.555
66666.666
77777.777
88888.888
99999.999
(each number is on a seperate line and there are some blank lines, but I need them to go into the output file as a place keeper)
Into a .txt file that looks like this:
**I also need to add an increment number at the beginning of each line to number the lines.
1,11111.111,22222.222,33333.333,text
2,44444.444,55555.555,66666.666,text2
3,77777.777,88888.888,99999.999,
the files that I have are in separate folders in a directory and have no file extension but they behave exactly like a standard text file.
I have tried all sorts of stuff but I am just not that well versed in programming. Here is the little bit of code that I havent deleted for the 100th time. gettting frustrated
:REFORMAT

I am using windows I have access to dos6 dos7 winxp 32 and win7 64
the text and text2 are text strings within the file, they are descriptors telling me what the numbers below mean and some of the descriptors are left out. I also need it to process more than the first four lines. Some files have up to 200 lines inside of them. Thank you so much for helping me. thank you so much dbenham here is the final result:
#echo off
setlocal enableDelayedExpansion
for /R %%F in (*.) do (
set /a ln=0
for /f %%N in ('type "%%F"^|find /c /v ""') do set /a cnt=%%N/4
for /l %%N in (1 1 !cnt!) do (
for %%A in (1 2 3 4) do (
set "ln%%A="
set /p "ln%%A="
)
set /a ln+=1
echo !ln!,!ln2!,!ln3!,!ln4!,!ln1!
)
) <"%%F" >"%%F.CSV"
Using nothing but pure native batch:
#echo off
setlocal enableDelayedExpansion
for %%F in (*.) do (
set /a ln=0
for /f %%N in ('type "%%F"^|find /c /v ""') do set /a cnt=%%N/4
for /l %%N in (1 1 !cnt!) do (
for %%A in (1 2 3 4) do (
set "ln%%A="
set /p "ln%%A="
)
set /a ln+=1
echo !ln!,!ln2!,!ln3!,!ln4!,!ln1!
)
) <"%%F" >"%%F.txt"
The above will process all files that have no extension in the current folder. If you want to recursively include all sub-folders, then add the /R option to the outer FOR statement.
The whole thing can be done quite simply using my REPL.BAT utility:
#echo off
for %%F in (*.) do (
<"%%F" repl "([^\r\n]*)\r?\n([^\r\n]*)\r?\n([^\r\n]*)\r?\n([^\r\n]*)\r?\n?" "$2,$3,$4,$1\r\n" mx|findstr /n "^"|repl "^(.*):" "$1," >"%%F.txt"
)
just a few modifications:
set /p doesnt delete a variable if input is empty, so you have to delete it before.
You missed a closing paranthese )
You have to use delayed expansion to use a changed variable inside parantheses
the counter.
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set count=0
FOR %%F IN (*.) DO IF NOT %%~XF==.BAT (
set "LINE1="
set "LINE2="
set "LINE3="
set "LINE4="
set count+=1
(
SET /P LINE1=
SET /P LINE2=
SET /P LINE3=
SET /P LINE4=
)<"%%F"
ECHO !count!,!LINE2!,!LINE3!,!LINE4!,!LINE1!>>"%%F.txt"
)
PAUSE >NUL

The task is to iterate through each line in a file named alts.txt. Then I grab the line and split it at the semicolon and print out the text before the semicolon and after the semicolon.
My file looks something like this...
username:password
username2:password2
username3:
My current code is this:
setlocal ENABLEDELAYEDEXPANSION
set file=alts.txt
for /f "tokens=*" %%A in (%file%) do (
set str=%%A
set "username=%str::="^&REM #%
set "pass=%str:*:=%"
echo username=%username% pass=%pass%
)
pause
If someone would be kind enough to show me my error and EXACTLY how to fix the error it would be greatly appreciated.
#echo off
setlocal ENABLEDELAYEDEXPANSION
set file=alts.txt
for /f "tokens=1,2 delims=:" %%A in (%file%) do (
set "$user=%%A"
set "$pass=%%B"
echo username=!$user! pass=!$pass!
)
pause
Be careful using %username%. It's a system variable. You can test writing echo %username% in the CMD prompt. You better choose another name for the Variable like i did.
If I have data file.txt and I want to read data from it into variable by using the command : set
How can I do that?
How can I move one line to another?
Read two lines from a file, based on your comments:
#echo off
setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in (file.txt) do (
set /a N+=1
set v!N!=%%a
)
set sn=!v1!
set s=!v2!
You may want to consider using a scripting language, if you want to process multiple lines.
This will give you line one in the variable:
#echo off
set /p var=<file.txt
echo "%var%"
pause
