Check These Out

create directory and set owner/group/mode in one shot

Replace spaces in a filename with hyphens
As long as you have perl based rename. You can check: =$ rename --help Unknown option: help Usage: rename [-v] [-n] [-f] perlexpr [filenames] That's the good one.

Get current Xorg resolution via xrandr

Start dd and show progress every X seconds
Adjust "sleep X" to your needs. *NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while).

change ownership en masse of files owned by a specific user, including files and directories with spaces
In the example, uid 0 is root. foo:foo are the user:group you want to make owner and group. '.' is the "current directory and below." -print0 and -0 indicate that filenames and directories "are terminated by a null character instead of by whitespace."

network usage per process
Nethogs groups bandwidth by process.

Remove all zero size files from current directory (not recursive)

Exclude grep from your grepped output of ps (alias included in description)
Surround the first letter of what you are grepping with square brackets and you won't have to spawn a second instance of grep -v. You could also use an alias like this (albeit with sed): alias psgrep='ps aux | grep $(echo $1 | sed "s/^\(.\)/[\1]/g")'

Resume scp of a big file

check the fucking weather
grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)
