pipe result into a variable...

[catalinnc]

hi...


for now i use this to set a variable from a tool output...

Code: Select all

tool.exe some.file > result.txt 
set /p _var=< result.txt
del result.txt

can this be done without the "middle man" result.txt?

meaning to pipe the tool.exe output into _var?


thanks...

This should do it in simple cases:

Code: Select all

for /f "delims=" %%l in ('tool.exe some.file') do set _var=%%l

Note however that if your tool may output an empty line, or one line with just spaces, the above command will not capture it. A more complex code would be needed in this case.
