Check These Out

pipe output to notify-send
you can put almost any command. $notify-send -t 0 "MOTD" "$(sed -n '/#^4/,/#$4/{/#^4\|#$4/!p}' motd2 | cut -d# -f2)" $notify-send -t 0 "readfile" "$(while read mess; do echo $mess;done < motd2)"

ls not pattern

left-right mouse buttons (left-handed)

geoip information
A function that takes a domain name as an argument

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Remove spaces from filenames - through a whole directory tree.
An example of zsh glob qualifiers.

Synchronize both your system clock and hardware clock and calculate/adjust time drift
Do not run this command if you already have ntpd running! This needs to run as root, for example with sudo: $ sudo ntpdate pool.ntp.org && sudo hwclock --systohc && sudo hwclock --adjust This command will fetch accurate time from NTP servers and synchronize your system clock, then it will use the system clock to synchronize your hardware clock, and will calculate the time drift.

check open ports without netstat or lsof

Adding Prefix to File name
Good old bracket expansion :-) For large numbers of files, "rename" will spare you the for-loop, or the find/exec...

Testing php configuration
Run the function phpinfo() on the shell
