Copy files and directories from a remote machine to the local machine

This command will copy files and directories from a remote machine to the local one. Ensure you are in the local directory you want to populate with the remote files before running the command. To copy a directory and it's contents, you could: ssh user@host "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf - This is especially useful on *nix'es that don't have 'scp' installed by default.

Pull up remote desktop for other than gnome/kde eg fluxbox

If the remote doesn't export its desktop (eg fluxbox, blackbox etc) then you need to run a x11vnc server there and a vncviewer at the local end. This command does the lot for you - it assumes that you can 'ssh' to the box without a password and that x11vnc is installed at the remote end.
This is sample output - yours may be different.

rdp() { ssh $1 sh -c 'PATH=$PATH:/usr/local/bin; x11vnc -q -rfbauth ~/.vnc/passwd -display :0' & sleep 4; vncviewer $1:0 & }

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.

find and reduce 8x parallel the size of PNG images without loosing quality via optipng

Start screen in detached mode

Start screen in detached mode, i.e., already running on background. The command is optional, but what is the purpose on start a blank screen process that way? It's useful when invoking from a script (I manage to run many wget downloads in parallel, for example).

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 block devices

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

Quick and Temporary Named Commands

* Add comment with # in your command * Later you can search that command on that comment with CTRL+R In the title command, you could search it later by invoking the command search tool by first typing CTRL+R and then typing "revert"

Monitor ElasticSearch cluster health - Useful for keeping an eye on ES when rebalancing takes place

Scan all open ports without any required program

find process associated with a port

e.g. fuser 25/tcp (see which pid is listening on smtp)

New files from parts of current buffer

On command mode in Vim you can save parts of the current buffer in another file. * The 'n' value represents the first line of the new file. * The 'm' value represents the last line of the new file. * newfile.txt is the newfile. The results are similar to this command in perl: $ perl -ne 'print if n..m' in.sql > out.sql
