doesnt seem to work

hobocopy is a cmdline utility that uses vss volume shadow service

windows inbuilt vssadmin doesnt seem to provide a way to copy a single
file from the shadow

You might be getting bitten by the way the script file is parsed/executed.
In the case of scripts processed with $$>a<, the script is condensed into a
single line with all newlines replaced with semicolons. So, while you think
that the result of this:

.shell -ci “uf ${$arg1}” ${resfol}
}

Would be a shell command of:

.\scripts\hobocopy %tmp%
.\scriptresults\%DATE:~6,4%%date:~3,2%%date:~0,2% shl*.tmp

It might actually be:

.\scripts\hobocopy %tmp%
.\scriptresults\%DATE:~6,4%%date:~3,2%%date:~0,2% shl*.tmp;

Due to the conversion of the newline at the end into a semicolon. This might
be enough to throw off the application and cause a failure.

Should be easy enough to test the theory, try adding a semicolon at the end
of the command and see if the application handles it. Alternative, Process
Monitor traces might be enlightening.

@###$$UO$UO$UP$UPU$PU$ !!@!#@##$*&*(&^#*&*^#$((_)*@)*@

thanks scott ill remember to add a space to and then a new line :slight_smile:

.\scripts\hobocopy C:\DOCUME~1\Admin\LOCALS~1\Temp
.\scriptresults\2011_08_10 shl*.tmp ;

or make all the script in one line
.\scripts\hobocopy C:\DOCUME~1\Admin\LOCALS~1\Temp
.\scriptresults\2011_08_10 shl*.tmp

instead of being normal

.\scripts\hobocopy C:\DOCUME~1\Admin\LOCALS~1\Temp
.\scriptresults\2011_08_10 shl*.tmp;

processmon traces are indeed enlightening
