bat to replace text from text file1 to file2 (relative search) - batch-file

Question

textfile1 is source and textfile2 is target
Example textfile1.txt:
server1.net 2100 /l /n /k port:2000,server2.net 2100 /l /n /k port:20000
textfile2.txt:
server3.net 2000 /l /k port:xxxx,server4.net 2000 /l /k port:yyyyy
I need to find "port:" characters in textfile1.txt and subst the port number (n character after "port:" characteres), in textfile2.txt
Note: portnumber is variable number in textfile1, but text: "port:" is fixed.
Thanks
Basically I need to put the same port numbers in textfile1 and textfile2

Answer 1

The Batch file below works with an unlimited list of servers in both text files and allows the port:nnnn option be included at any place in the line. It does not check for any errors to made it simpler.
#echo off
setlocal EnableDelayedExpansion
rem Read data from both files
set /P "data1=" < textfile1.txt
set /P "data2=" < textfile2.txt
rem Replace "port" data in all servers
:nextServer
rem Get port number after "port:" in first data and eliminate it
for /F "tokens=1* delims=," %%a in ("%data1:*port:=%") do set port1=%%a& set data1=%%b
rem Replace port number in second data and change colon by semicolon
for /F "tokens=1 delims=," %%a in ("%data2:*port:=%") do set data2=!data2::%%a=;%port1%!
rem Pass to next server, if any
if defined data1 goto nextServer
rem Output result restoring colons
echo %data2:;=:%
For example, with this data:
server1.net 2100 /l /n /k port:2000,server2.net 2100 /l /n /k port:20000,server5.net 2100 /l /n /k port:1234
server3.net 2000 /l /k port:xxxx,server4.net 2000 /l /k port:yyyyy,server6.net 2000 /l /k port:zzzz
The output is:
server3.net 2000 /l /k port:2000,server4.net 2000 /l /k port:20000,server6.net 2000 /l /k port:1234

I don't see why you want to do this task with batch - it would be much simpler using another scripting language like VBScript, JScript, or perhaps PowerShell.
But here is a native batch solution. My solution makes no assumption as to the order of the options in each command. It allows for any number of options both before and after /port:nnnn.
#echo off
setlocal enableDelayedExpansion
::read the line from textfile1
set "str="
<"textfile1.txt" set /p "str="
if not defined str exit /b
::enclose each command in quotes
set "str="!str:,=","!""
::extract the port from each command into an array
set /a n=0
for %%A in (!str!) do (
set "cmd=%%~A"
set /a n+=1
for /f %%B in ("!cmd:*port:=!") do set "port!n!=%%B"
)
::read the line from textfile2
set "str="
<"textfile2.txt" set /p "str="
if not defined str exit /b
::enclose each command in quotes
set "str="!str:,=","!""
::process each command
set /a n=0
set "ln="
for %%A in (!str!) do (
set "cmd=%%~A"
REM break the command into 2 parts, discarding port:
REM %%B = before port
REM %%E = after port
for /f "tokens=1* delims=," %%B in ("!cmd:port:=,!") do (
for /f "tokens=1*" %%D in ("%%C") do (
set /a n+=1
REM transfer !n! into %%N
for %%N in (!n!) do (
REM build the new line
set "ln=!ln!,%%B port:!port%%N! %%E"
)
)
)
)
::remove space before comma
set "ln=!ln: ,=,!"
::write the result back to textfile2
>"textfile2.txt" echo !ln:~1!

A little more clarification on what you're looking to do in the long-term may help, but in the meantime, here is a script I just wrote and tested and it does exactly what you're asking.
for /f "tokens=6,12 delims=, " %%a in (textfile1.txt)do (
set portOne=%%a
set portTwo=%%b
call :writeTextTwo
)
type texttwo_temp>textfile2.txt
goto :EOF
:writeTextTwo
for /f "tokens=1-12 delims=, " %%c in (textfile2.txt)do (echo %%c %%d %%e %%f %portOne%,%%h %%i %%j %%k %portTwo% >>texttwo_temp )
goto :EOF
I hope this helps.
