FOR /F Tokens script to read first line only.
Posted on 2009-04-09
I'm currently using the line below in a batch script to find data in a text file.
for /f "tokens=3,4,5,6" %i in (myfile.txt) do @echo %i %j %k %l
The data (or columns) I want (3,4,5,6) are only from the 1st line of text in my input file myfile.txt.
My script will read the entire file and I'll end up with way more output than I need. I'd like to just scan the first line in my file for the data then exit. What do I need to do?
-thanks!

for /f "tokens=3,4,5,6" %i in (myfile.txt) do @echo %i %j %k %l >> %temp%\asdf.tmp
set /p var_FirstLine=<%temp%\asdf
echo %var_FirstLine%
set /p var_FirstLine=<%temp%\asdf
echo %var_FirstLine%
Thank you. The only correction I had to make was my own really, I have to put %%i (and for the other VARs too) in a batch script. Need double percent signs instead of single.
SHIFT-3 the other way is just to do this:
for /f "tokens=3,4,5,6" %i in (myfile.txt) do @echo %i %j %k %l & goto :eof
for /f "tokens=3,4,5,6" %i in (myfile.txt) do @echo %i %j %k %l & goto :eof
