| COMMANDS WORTH REMEMBERING

My scripts:
sc show most-common quick-scripts
greplogs blah search all my log files (named ToDo.txt) for "blah"
greplogs blah -C 3 search all my log files (named ToDo.txt), and show 3 surrounding lines of context
grepcode blah -C 3 same, but search code files underneath the current dir (h|hpp|cpp|pl|php)
restart_process_as_needed.pl name=#path/file#
checks for process named 'file'; if not found, starts path/file
pk substring prompt to kill all processes with 'substring'
General-purpose:
cp -axv drive drive_backup clone an unmounted linux system
ps ax|grep blah show running processes with "blah" in them
lsof -c cp show open files for any process starting with "cp"
lspci list all the hardware using the PCI bus (video cards, etc)
watch #command# repeat the command every 2 secs (default), showing output
tail -f #logfile# display the tail end of the logfile, in realtime
shutdown -rF now reboot, forcing an fsck on startup (or, put a [forcefsck] file in drive root)
fuser -m /dev/hdb1 find open files on a drive, then processes that have the file(s) open
/dev/hdb1: 538
ps auxw|grep 538
donncha 538 0.4 2.7 219212 56792 ? SLl Feb11 11:25 rhythmbox
wc -l file count lines - can pipe to it too
find / -name "libjpeg*" brute-force find (in this case, all libraries starting with jpeg...)
iostat -dx 5 report on drive % utilization etc ("emerge systat" to get it)
iotop top for io, of course
hdparm -t /dev/sda tests actual speed of hard drive
Ubuntu-specific:
xrandr --output DVI-I-2 --off && xrandr --output DVI-I-2 --auto --right-of DVI-I-1 fixes lost monitor, also try arandr
