FOR with LFN?

SET _lfn=c:\my documents\lfn.txt
FOR /F "tokens=1* delims==" %%G IN (%_lfn%) DO SET %%G=%%H

A problem I had for a long time now, but is it possible to use for commands with a long file name, or do you need it to be in the same directory to process for commands? I tried double quotes and single quotes but they didnt work, maybe the context is wrong

Re: FOR with LFN?

you missed an underscore

SET _lfn

or else just use %lfn%

Re: FOR with LFN?

For once, Windows Help has all the answers.  Important bits are in bold...

<snip>

    or, if usebackq option present:

FOR /F ["options"] %variable IN (file-set) DO command [command-parameters]
FOR /F ["options"] %variable IN ('string') DO command [command-parameters]
FOR /F ["options"] %variable IN (`command`) DO command [command-parameters]

<snip>

usebackq     - specifies that the new semantics are in force,
                  where a back quoted string is executed as a
                  command and a single quoted string is a
                  literal string command and allows the use of
                  double quotes to quote file names in
                  file-set*.

<snip>

*I've corrected the slightly misleading original word that is here.

Thus your corrected FOR statement would need to look something like this:

FOR /F "usebackq tokens=1* delims==" %%G IN ("%_lfn%") DO SET %%G=%%H

Good point, I've just edited the FOR /F page to add that usebackq option.

thanks bluesxman
