gzip: Environment

1 5 Environment

1 The obsolescent environment variable ‘GZIP’ can hold a set of default
1 options for ‘gzip’. These options are interpreted first and can be
1 overwritten by explicit command line parameters. As this can cause
1 problems when using scripts, this feature is supported only for options
1 that are reasonably likely to not cause too much harm, and ‘gzip’ warns
1 if it is used. This feature will be removed in a future release of
1 ‘gzip’.

1 You can use an alias or script instead. For example, if ‘gzip’ is in
1 the directory ‘/usr/bin’ you can prepend ‘$HOME/bin’ to your ‘PATH’ and
1 create an executable script ‘$HOME/bin/gzip’ containing the following:
1
1 #! /bin/sh
1 export PATH=/usr/bin
1 exec gzip -9 "$@"
