User: iridium172
Functions: grep kill ps

Add that and "cont () { ps -ec | grep $@ | kill -SIGCONT `awk '{print $1}'`; }" (without the quotes) to you bash profile and then use it to pause and resume processes safely

$class=ExampleClass; $path=src; for constant in `grep ' const ' $class.php | awk '{print $2;}'`; do grep -r "$class::$constant" $path; done

getent shadow | grep '^[^:]\+:!' | cut -d: -f1
getent shadow | while IFS=: read a b c; do grep -q '!' <<< "$b" && echo "$a LOCKED" || echo "$a not locked"; done

User: sputnick
Functions: echo getent grep read
man 5 shadow

I think it's more reliable, because

passwd -S

dont show "locked" but "L" as second field on my Archlinux for a particular user.

( unixhome alternative ).

awk -F":" '{ print $1 }' /etc/passwd | while read UU ; do STATUS=$(passwd -S ${UU} | grep locked 2>/dev/null) ; if [[ ! -z ${STATUS} ]] ; then echo "Account ${UU} is locked." ; fi ; done
mtx -f /dev/sg13 status | grep EXPORT | cut -c 56-63
2009-12-18 04:21:51
User: JamesyBoi
Functions: cut grep

This reports directly using mtx what Tape is in the mailslot (Import/Export tray) on most autoloaders.

You will need to change /dev/sg13 to your autloader device file and adjust the 63 at the end to your tape label character length(ie 63 for 8 characters 64 for 9 characters)

watch -d 'sudo smartctl -a /dev/sda | grep Load_Cycle_Count ; sudo smartctl -a /dev/sda | grep Temp'
2009-12-15 00:15:24
User: vxbinaca
Functions: grep sudo watch

This command is a great way to check to see if acpi is doing damage to your disks by agressivly parking the read arm and wearing down it's life. As you can see, mine has lost half its life. I'm sure this could be shortened though somehow. It will use smartctl to dump the stats and then grep out just the temperature and load cycles for the disk (a load cycle is when a the read arm comes out of park and wears on the drive).

wget -q -O - http://someonewhocares.org/hosts/ | grep ^127 >> /etc/hosts

od -c <FILE> | grep --color '\\.'

User: sputnick
Functions: grep od
Tags: od

For fancier and cleaner output, try the following snippet :

showendlines(){ while read i; do od --address-radix=n --width=$(wc -c <<< "$i") -c <<< "$i" | perl -pe 's/.\K\s{2,3}//g'; done < $1 | grep --color '\\.'; }

Now you can run that with :

showendlines <FILE>
