Bash Quick Start Guide

Getting all the arguments

We could adapt our preceding mkcd function to a new function, mkls, that creates directories and then prints them with ls -dl. The -d option to ls lists the directory itself, rather than its content. This implementation works well:

bash$ mkls() { mkdir -- "$1" && ls -dl -- "$1" ; }
bash$ mkls newdir
drwxr-xr-x 2 bashuser bashuser 4 2018-07-17 20:30:33 newdir/

However, this approach only allows us to create one directory. Because both mkdir and ls accept more than one directory name, we could create two of them like this:

bash$ mkls2() { mkdir -- "$1" "$2" && ls -dl -- "$1" "$2" ; }
bash$ mkls2 newdir1 newdir2
drwxr-xr-x 2 tom tom 4 2018-07-17 20:32:03 newdir1/
drwxr-xr-x 2 tom tom 4 2018-07-17 20:32:03 newdir2/
