You can set up aliases to easily repeat common commands. ```bash alias <alias keyword>='<command>' ``` For example, set up an alias to print a file tree (some OS already have this command but [[Git for Windows]] does not). ``` bash alias tree='find . -print | sed -e "s;[^/]*/;|____;g;s;____|; |;g"' ``` Note there are no spaces between the alias keyword, the equals sign, and the command (`tree='find...'`).
