What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Selecting a random file/folder of a folder

Also looks in subfolders

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"

List your MACs address

The output of ifconfig is localized, using it will fail in non-English environment. "ip" command in iproute2 provides a consistent output and thus is more robust

Insert the last argument of the previous command

for example if you did a: $ ls -la /bin/ls then $ ls !$ is equivalent to doing a $ ls /bin/ls

Rename files in batch

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

shell function to underline a given string.

underline() will print $1, followed by a series of '=' characters the width of $1. An optional second argument can be used to replace '=' with a given character. This function is useful for breaking lots of data emitted in a for loop into sections which are easier to parse visually. Let's say that 'xxxx' is a very common pattern occurring in a group of CSV files. You could run $ grep xxxx *.csv This would print the name of each csv file before each matching line, but the output would be hard to parse visually. $ for i in *.csv; do printf "\n"; underline $i; grep "xxxx" $i; done Will break the output into sections separated by the name of the file, underlined.

Signals list by NUMBER and NAME

This command seems to achieve the similar/same goal.

list block devices

Shows all block devices in a tree with descruptions of what they are.

Preview of a picture in a terminal

This command allows you to see a preview of a picture via the terminal. It can be usefull when you are ssh'ing your server without X-forwarding. To have en example of the output you can get with this command see http://www.vimeo.com/3721117 Download at http://inouire.net/image-couleur.html Sources here: http://inouire.net/archives/image-couleur_source.tar.gz
