问题
I need to parse a tab-delimited text file by grabbing specific columns, like columns 1 and 5, and output each of these columns into a text file. Please find an example of the data file, and the code:
Data file:
COL1 COL2 COL3 COL4 COL5 COL6
123 345 678 890 012 234
234 456 787 901 123 345
etc
Batch file:
@echo off & setlocal
For /F "tokens=1,5*" %%i in (myFile.dat) do call :doSomething "%%i" "%%j"
goto :eof
:doSomething
Set VAR1=%1
Set VAR2=%2
@echo %VAR1%>>Entity.txt
@echo %VAR2%>>Account.txt
This works, however, the For loop stops on the first line.
Could you help me in finding the issue?
回答1:
Your code works fine for me, but maybe try this shortened version?
@echo off
for /F "tokens=1,5*" %%i in (myFile.dat) do (
echo %%i >>Entity.txt
echo %%j >>Account.txt
)
回答2:
While I would recommend using the shortened version by Bali C, the reason the code above might be stopping after the first line is because the goto :eof or exit command is not at the end of the :doSomething function.
@echo off & setlocal
For /F "tokens=1,5*" %%i in (myFile.dat) do call :doSomething "%%i" "%%j"
goto :eof
:doSomething
Set VAR1=%1
Set VAR2=%2
@echo %VAR1%>>Entity.txt
@echo %VAR2%>>Account.txt
goto :eof
Or if Extensions are disabled, it would be outputting the following error message:
/F was unexpected at this time.
To resolve this add EnableExtensions to your setlocal command.
@echo off & setlocal EnableExtensions

your code is working fine, check the output below.
Account.txt
"COL5"
"012"
"123"
""
Entity.txt
"COL1"
"123"
"234"
"etc"
