Human Readable $PATH output
Use this to nicely format the $PATH variable:
echo -e ${PATH//:/\n}Change default shell
Use chsh utility to change your default shell:
# list out the shells available with -l
chsh -l
# if that doesn't work try
cat /etc/shells
# /bin/bash
# /bin/zsh
# /bin/fish
# set the default shell (with -s) to fish
chsh -s /bin/fish
# set the default shell (with -s) to zsh
chsh -s /bin/zshKill process on port
List any process running on port 8000
lsof -i:8000Output will look similar to this.
COMMAND PID USER
chrome 16085 iamuserThen kill it with kill.
kill -9 16085Add an alias
# open your bash_profile with nano
nano ~/.bash_profile
# add your alias
alias f='fish'
# ctrl+x then y to saveSort alphabetically
You may find that commands like ll are under your ~/.bashrc file,
if not then add the following as an alias:
ls -lart | sort -k9,9See file permissions
If you need to set the permission on a file (with chmod) but don’t
know what the permissions of similar files are like you can use
stat, the following command displays the permissions of the contents
of the .ssh/ folder:
stat -c "%a %n" ~/.ssh/*Open the SSH agent each time you open a new terminal.
Tired of having to enter your SSH password each time you want to do a git operation?
Add the following to your ~/.bashrc file.
# nano ~/.bashrc
[ -z "$SSH_AUTH_SOCK" ] && eval "$(ssh-agent -s)"Search Bash history
Want to search for an entry in your Bash history?
Use Ctrl+r then enter your search term.
Remove command from bash history
Accidentally added your password as a bash command?
To remove that from the bash history:
# list out history with
historyThen take the number from the output:
471 ssh-agent
472 exit
473 kill 53111
474 super secret password
475 historyThen delete the line you want removed:
history -d 474Check your history again and gone until you do it again.
