Now what do you suppose this is all about? ...

alan@affront ~ $ whoami
alan

alan@affront ~ $ groups alan
wheel audio cdrom video usb users portage cron plugdev eclipse games alan

alan@affront ~ $ ls -l /usr/lib64/eclipse-3.1/

alan@affront ~ $ mkdir /usr/lib64/eclipse-3.1/plugins/dir
mkdir: cannot create directory `/usr/lib64/eclipse-3.1/plugins/dir': Permission denied

According to the above I am in the eclipse group, as is the plugins directory with corresponding write permissions, yet I cannot create a directory or other file within plugins.

Also, whats this about?

alan@affront ~ $ id -Gn
alan wheel cron audio cdrom video games usb users portage plugdev

alan@affront ~ $ id -Gn alan
alan wheel audio cdrom video usb users portage cron plugdev eclipse games

I suspect that this discrepancy is related to the problem.

Im on Gentoo (above is in bash), not that that should make a difference.

Any explanations?

Try newgrp eclipse and see what happens.

Try newgrp eclipse and see what happens.

Hi,

No output, no change. The eclipse group existed already ...

newgrp doesn't create a group. It switches your current default group.
