sshdo, an alternative to sudo

Run program as root by SSH key forwarding instead of sudoers. Put this alias line in .bashrc or wherever you like. Alias arguments might need extra escaping. You might wonder about security. But you'd block out root login as much as possible of course. In sshd_config you put this: PermitRootLogin no Match Address 127.0.0.1 PermitRootLogin without-password
This is sample output - yours may be different.

alias sshdo='ssh -q -t root@localhost -- cd $PWD \&\& sudo'

Alias cd to record your directory travelling

You know there 'cd -' to go to the previous directory you were standing before, but it will no record more than one. With these alias you can now record all your directory changes and go back whenever you need it. However you will have to get accustomed to use 'cd ~' from now on to go to your home directory.

alias cd='pushd'; alias cd-='popd'

alias ps | grep

This is an attempt to get a command which I can alias. It's ugly but it works. I'm hoping someone can suggest a cleaner version. I have tried.... # alias kfire="for i in $( ps aux | grep [F]irefox | awk \'{print $2}\' ); do kill $; done" # alias kfire=`kill $(ps aux | grep [F]irefox | awk '{print $2}' | tr '\n' ' ')` # alias kfire='ps au | grep -i [F]irefox | awk \'{ print $2 \'} ' and they all fail in a .bashrc I've tried escaping the quotes and can't find a way to make the single quotes ' that awk wants work. Maybe I'm just stubborn but I don't want to put in a little #!/bin/bash file just so I can kill a firefox process all in one stroke. This script works (it kills the process before it errors out)... it's just ugly and there may be a pretty way to do this. Show Sample Output

An alias for pasting code/data into terminal without it doing anything. Add to .bashrc

cn stands for "Cat Null" . The idea is that sometimes you run across something on maybe a webpage - like commandlinefu - that you want to try out on your terminal. You could put a '#' in and then paste it, but what if it is several lines? . This command will echo the pasted characters to the screen and divert them to the bit bucket. . Put this simple alias in your .bashrc, hit cn, paste away, and hit a ctrl+c or a ctrl+d when you are done to get your prompt back. Show Sample Output
This is sample output - yours may be different.
```
cn

paste in code or data that will not cause issues, make your terminal unreadable or 
actually rm -rf /
.
hit a <ctrl+c> or a <ctrl+d> when you are done pasting to get your prompt back

MacOS: Make the terminal app always quit when

When you use the "exit" command in a Linux terminal window, it not only closes the terminal window itself but also the terminal emulator app, such as GNOME Terminal or Konsole, that it belongs to. If you use the "exit" command on macOS, however, Terminal.app still shows a dot below its Dock icon and is still running in the background. This alias, when entered into ~/.zshrc, overrides this behavior.
This is sample output - yours may be different.

alias exit="killall Terminal"

Always run apt-get as root

apt-get must be run as root, and it is useless to run it as your own user. So just run it as root. Saves you the "sudo !!" every time you're adding a package.

Multi-line grep

Using perl you can search for patterns spanning several lines, a thing that grep can't do. Append the list of files to above command or pipe a file through it, just as with regular grep. If you add the 's' modifier to the regex, the dot '.' also matches line endings, useful if you don't known how many lines you need are between parts of your pattern. Change '*' to '*?' to make it greedy, that is match only as few characters as possible. See also http://www.commandlinefu.com/commands/view/1764/display-a-block-of-text-with-awk to do a similar thing with awk. Edit: The undef has to be put in a begin-block, or a match in the first line would not be found.

get some information about the parent process from a given process

cd to (or operate on) a file across parallel directories

This is useful for quickly jumping around branches in a file system, or operating on a parellel file. This is tested in bash. cd to (substitute in PWD, a for b) where PWD is the bash environmental variable for the "working directory"

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"
