.bash_profile is a file that bash invokes (or more technically sources) before the start of a new bash session. In .bash_profile, we have the opportunity to add variables, functions, and aliases to customize our bash environment and provide reusable functionality.
In this lesson, we’ll look at adding a git_sync alias as well as a ll alias. Aliases act like shortcuts and save us time and typing at the terminal. .bash_profile is a good spot for smaller functions and aliases.
Note that on most linux distributions you'll use .bashrc instead of .bash_profile.
1. cd ~
2. vim .bash_profile
3. Add alias
alias ll="ls -laG" alias git_sync="git pull -r && git push"
4. apply changes
source .bash_profile
5. To check what the alias does:
$ ll
