Greetings: I discovered today that the GROUPS variable is special in Bash.
I moved some scripts to a new box, and they stopped working. On this box, /bin/sh linked to /bin/bash instead instead of /bin/dash. Scripts of of this form... #!/bin/sh GROUPS='foo bar' # do something with $GROUPS here had worked because GROUPS had no special meaning under /bin/dash. The script is invoked with /bin/sh (linked to /bin/bash), so I had expected Bash POSIX compliance to take over. It did not. Is this considered a bug? Should bash, invoked with "--posix" or as "sh", omit the special treatment of variables such as GROUPS? -- Jason Franklin
