We can put this inside a function:

fxray() { curl -s http://urlxray.com/display.php?url="$1" | grep -o '<title>.*</title>' | sed 's/<title>.*--> \(.*\)<\/title>/\1/g'; }; fxray http://tinyurl.com/demo-xray

If we want files with more than one extension, like .tar.gz, only appear the latest, .gz:

ls -Xp /path/to/dir | grep -Eo "\.[^./]+$" | uniq
s="StrinG"; echo ${s,,}

Another alternative is to define a function:

lower() {

echo ${@,,}

}

lower StrinG

'ac' is included in the package 'acct', which is described as "The GNU Accounting utilities for process and login accounting". Other interesting flags are:

* print statistics for a specified user

ac -d username

* print statistics for all the users

ac -p

With my command, the output is also printed in a sexagesimal, more readable, style.
