: reckoningA quick script to compile a LaTeX file to a PDF:
#!/bin/bash FILE=$1 if [ -a $FILE.tex ]; then latex $FILE && dvipdf $FILE.dvi && rm -f $FILE.log $FILE.aux $FILE.dvi else echo $FILE.tex does not exist! exit 1 fi
There are some cases that you need a Linux box to never halt—never ever. Even if you specifically request it…
To protect yourself from yourself one could do the following:
cd /sbin/ mv halt halt.real chmod 000 halt.real ln -s reboot halt mv poweroff poweroff.real chmod 000 poweroff.real ln -s reboot poweroff
It would also be wise to modify /etc/init.d/halt. Find the following section:
# See how we were called. case "$0" in *halt) message=$"Halting system..." command="/sbin/halt" ;;
and turn it into
# See how we were called. case "$0" in *halt) echo $"$0: this system may not be halted!" exit 1 message=$"Halting system..." command="/sbin/halt" ;;
.
Also, you may want to set up an exception in sudoers (always use visudo to edit it). Here’s a simple way of prohibiting users to “sudo shutdown -h now” or “sudo halt“:
Cmnd_Alias HALT = /sbin/shutdown, /sbin/halt
%wheel ALL=(ALL) ALL, !HALT
Should you need to reboot, sudo reboot should suffice.
Warning: If your box is connected directly to a UPS you might want to refrain from messing up with halt.
