Shelling It Out


A few handy tid bits of shell commands to help one allong!

To get the date of yesterday:

To get your IP address for all interfaces (including lo):
/sbin/ifconfig | grep "inet addr" | cut -d ":" -f 2 | cut -d " " -f 1

To get a single interface IP address (replace $interface with the one you want):

/sbin/ifconfig $interface | grep "inet addr" | cut -d ":" -f 2 | cut -d " " -f  1

Take a screen shot:
xwd -root -out screenshot

import -window root -quality 100 pic.jpg

If using xwd you can view it with xwud the Gimp and many others. To get a single window try:

xwd -out windowshot
