[PATCH rt-tests 3/4] rt-tests: workaround poor gzip implementations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some 'gzip' implementations, in particular 'pigz' don't properly handle
the '-c' argument if it's passed after the name of the input files.

Work around this by putting the '-c' option before the file names.

Inspired by patches in OpenEmbedded by Robert Yang and Kai Kang.
