Low bandwidth copy

So, you have to copy one directory into another on your server and you don’t want to kill the machine?

Instead of

cp -r master master_copy

use

rsync --bwlimit=30000 -av master/ master_copy/

The –bwlimit=KBPS switch is for limiting I/O bandwidth.

Grep with context

Small thing but extremely useful. Getting context with grep.

-C – Print num lines of leading and trailing context surrounding each match. The default is 2 and is equivalent to -A 2 -B 2. Note: no whitespace may be given between the option and its argument.

grep -C 5 file.txt
