Quick Grep Tricks

Grep for x or y, eg:

ls -lR | grep "x\|y"

Removing blank lines from output:

grep -v "^$" filename

“^ is the start of line expression and $ is the end of line expression, in this case we are asking for a line containing the line beginning and line ending with nothing in between.”
