Check These Out

recursively change file name from uppercase to lowercase (or viceversa)
Example of zsh globing, glob qualifier, and substitution: -Q state that the parameter will contain a glob qualifier. (**/)(*) is recursive (.) is our glob qualifier, with states the match is a file "." The first parameter $1, is then substituted with $2 but with lowercasing '(L)' ... a (U) would of course be from lower to upper.

Find out current working directory of a process

Prefix every line with a timestamp
Useful to add a timestamp to every line printed to stdout. You can use `-Ins` instead of `-Iseconds` if you want more precision.

Open screen on the previous command
I often find myself wanting to open screen on whatever command I'm currently running. Unfortunately, opening a fresh screen session spawns a new bash session, which doesn't keep my history, so calling screen directly with the previous command is the only way to go.

Poor man's unsort (randomize lines)

See system users

Pipe STDOUT to vim
The hyphen tells vim to open from STDOUT - saves having to create temporary files.

Scans for open ports using telnet

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Temporarily ignore known SSH hosts
you may create an alias also, which I did ;-) alias sshu="ssh -o UserKnownHostsFile=/dev/null "
