After a lengthy unpack operation of multiple archives with a command line like this
7zg x -an -ai@filelist -otarget_dir\* -scsWIN
7zg presents a dialog with a list of errors that occured:
1 CRC failed in 'file1.ext'. File is broken.
3 CRC failed in 'file2.ext'. File is broken.
It would be nice if I could specify path and name of a log file to be written. It would be even nicer if one could set an environment variable with default values (both WinRAR and UPX support a RAR / UPX environment variable, btw).
When an additional switch -sh is given, 7zg / 7z / 7za should not show the final dialog and shutdown the system instead.
