Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Lists the size of certain file in every 10 seconds

watch is a command especially designed for doing this job

statistics in one line

In this example, file contains five columns where first column is text. Variance is calculated for columns 2 - 5 by using perl module Statistics::Descriptive. There are many more statistical functions available in the module.

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)"

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"

Perl Command Line Interpreter

Can also just use the debug mode like this.

ping with timestamp

http://public-dns.info gives a list of online dns servers. you need to change the country in url (br in this url) with your country code. this command need some time to ping all IP in list.
