open manpage and search for a string

This will open the manpage for "foobar", and display all instances of "searched_string". You can traverse through them by pressing "n"

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.

make image semi-transparent

Download a file securely via a remote SSH server

This command will download $file via server. I've used this when FTP was broken at the office and I needed to download some software packages.

Paste hardware list (hwls) in html format into pastehtml.com directly from console and return URI.

In this Linux box i need to become root to get the complete hardware list, so either become root before or call it with sudo as i did, your choice.

ssh autocomplete based on ~/.ssh/config

I sue this in my .bashrc file This will also do auto-completion for scp and sftp

fuman, an alternative to the 'man' command that shows commandlinefu.com examples

Example: fuman sed

Convert tab separate file (TSV) to JSON with jq

With this command you can convert a tab separate file (TSV) into a JSON file with jq. For example, this input.tsv i-0b9adca882e5e6326 172.16.0.188 i-088dd69e5c3624888 172.16.0.102 i-0e70eac180537d4aa 172.16.0.85 will produce the showed output.

history autocompletion with arrow keys

This will enable the possibility to navigate in the history of the command you type with the arrow keys, example "na" and the arrow will give all command starting by na in the history.You can add these lines to your .bashrc (without &&) to use that in your default terminal.

Clear terminal Screen

Probably the quickest / easiest way to clear the screen.
