Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id

Creates the .ssh directory on the remote host with proper permissions, if it doesnt exist. Appends your public key to authorized_keys, and verifies it has proper permissions. (if it didnt exist it may have been created with undesireable permissions). *Korn shell syntax, may or may not work with bash

Speed Up WAN File Transfer With Compression

If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...

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.

watch the previous command

If you just executed some long command, like "ps -aefww | grep -i [m]yProcess", and if you don't want to retype it or cycle backwards in history and waste time quoting it, then you can use history substitution.

Remove newlines from output

Remove newlines from output. One character shorter than awk /./ filename and doesn't use a superfluous cat. To be fair though, I'm pretty sure fraktil was thinking being able to nuke newlines from any command is much more useful than just from one file.

Save a file you edited in vim without the needed permissions

Calls sudo tee like all the other lines, but also automatically reloads the file. Optionally you can add command Wq :execute ':W' | :q and command WQ :Wq to make quitting easier

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Disable system bell in an X session

Execute this command in a terminal to disable the system-bell during X-session lifetime.

Rip a video for archiving, from any site

Download video files from a bunch of sites (here is a list https://rg3.github.io/youtube-dl/supportedsites.html). The options say: base filename on title, ignores errors and continue partial downloads. Also, stores some metadata into a .json file plz. Paste youtube users and playlists for extra fun. Protip: git-annex loves these files

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"

.inputrc keybinding to wrap current line in inotifytools for instant compile/test-as-you-save-loop

Assuming you've written all of make -j hfst-tokenize && echo doavtter gr?dakursa|./hfst-tokenize --gtd tokeniser-gramcheck-gt-desc.pmhfst and want that to execute every time you :w in vim (or C-xC-s in Emacs), just hit and it'll turn into $ while true; do ( make -j hfst-tokenize && e doavtter gr?dakursa|./hfst-tokenize --gtd tokeniser-gramcheck-gt-desc.pmhfst ); inotifywait -q -e modify -e close_write *; done with the cursor right before the ')'. Hit enter, and it'll run on each save. Requires the package inotify-tools installed.
