- Too lazy to reboot.
- Having too much running important things.
- Must do it now !
No more reboot !
the newgrp command is used to start a new session having the group or all new group reread from the groups configuration.What it does, it starts a new bash session and newly invoked commands use the new groups.
How to do it ?
In your favourite DE press ALT + F2, then type:
bash -c 'newgrp <<< dolphin' (or use nautilus, rox, etc)
Explanation
- bash will open a new shell session and invoke a command
- newgrp will reload that session
- and STDIN redirection will inject commands e.g dolphin into the new session
Caveats
- We cannot create new directories/files
- Renaming files raises error, the renamed file visually looks changed, but refreshing the directory will revert the name.
- Creating new file does the same thing.
- Creating new directory does the same thing.
What's possible
Only edit existing files - Useful for Sublime and such to quickly edit something.For using an IDE
- it's useful that we first chown the directory to our username
- create the project with the IDE
- play around, until everything is written
- chown back to the intended group
- run the ide either with:
bash -c 'newgrp <<< ~/.local/bin/idea-IU/bin/idea.sh' - alternatively run it in dolphin's terminal, but that's silly
Troubleshoot and tricks
If you need to pass arguments to the command:bash -c 'newgrp <<< "dolphin ~/bin"'Notice the double quotes surround the command, well, without them nothing will happen :D.
Alternative
sg couchbase -c dolphinmuch like the newgrp command, however sg accepts a command
Caveats
you must know the group, alas only one group.Which means this command sucks!
