Feeding Your Inner Developer
Simply put
date -d '1 day ago' +'%Y-%m-%d' # For multiple days date -d '7 days ago' +'%Y-%m-%d'
If you wish to place in a shell script:
RMDATE=$(date -d '7 days ago' +'%Y_%m_%d')
will place for example ‘2013-07-01’ in the RMDATE variable which of course you can use like
echo $RMDATE
I wrote a lil script to help out with this.. The syntax is as follows:
finddrive.py sda
How this works is by lighting up the corresponding drive on the front panel for about 3 seconds.
#!/bin/sh cmd="dd if=/dev/$1 of=/dev/null" seconds=3 echo "Check front panel for indicator light" $cmd& cmdpid=$! sleep $seconds if [ -d /proc/$cmdpid ] then # echo "terminating program PID:$cmdpid" kill $cmdpid fi
