 |
|
The 'poweroff' command works great as root but as user I get ... | Code: | | -bash: poweroff: command not found |
I tried putting this in my user .bashrc | Code: | | alias poweroff='/sbin/shudown -h now' |
Any ideas?
Thanks, olias

| You need to either be root, or have 'shutdown' suid root, I think. |

You can also change ctrl-alt-delete to shutdown instead of rebooting. It's very convenient if you don't reboot often. This is done in the file /etc/inittab (just replace reboot what it says with this)
| Code: | # What to do at the "Three Finger Salute".
ca:12345:ctrlaltdel:/sbin/shutdown -ha now |

Try setting permissions of /sbin/poweroff, as root, as follows:
| Code: | | chmod 4755 /sbin/poweroff |
then at a (quailfied) user prompt, /sbin/poweroff shuts the system down. Also useful for binaries telinit, shutdown, and reboot ! |

| Code: | | alias shutdown="sudo shutdown -h now" |
You can use visudo to allow normal users use sudo with shutdown without requiring a password. Personally, I perfer to leave itprompting m for my password. It's useful for when I type
while half asleep, only to have the shell history mechanism pickup "shutdown". If it prompts for a password, I get a chance to Control-C out of it

You can also configure sudo to allow certain commands to run without a password - useful for shutting down your PC with a remote control.
See 'man sudoers' |
