QUESTION
I did a ton of reading and searching about a way to have Get-ChildItem return a dir listing in wide format, in alphabetical order, with the number of files and directories in the current directory. Here is a image of what I ended up with, but not using GCI.

Install bargs
Download bargs.sh (10 kilobytes) and the bargs_vars template Latest version (master) curl -sL --remote-name-all bargs.link/{bargs.sh,bargs_vars} Specific release (v1.x.x) curl -sL --remote-name-all bargs.link/1.1.4/{bargs.sh,bargs_vars}
Reference to bargs_vars - do one of the following Default behavior - bargs.sh and bargs_vars are in the same folder Specific bargs_vars path - export BARGS_VARS_PATH="${PWD}/path/to/my_bargs_vars", see tests.sh
Edit bargs_vars - Declare arguments/variables, here are some ground rules The delimiter --- is required once at the beginning, and twice in the end Characters which are not supported: =, ~, \, ', " The last variable bargs is necessary, comments below It's best to source bargs at the top of the bash script. Do not add set -o pipefail before source bargs.sh
Add one of the following lines at the beginning of your application (see Usage below) bargs.sh is in the root folder of your project (just like in this repo) source "${PWD}"/"$(dirname ${BASH_SOURCE[0]})"/bargs.sh "$@" bargs.sh is in a subfolder, for example tools source "${PWD}"/"$(dirname ${BASH_SOURCE[0]})"/tools/bargs.sh "$@"
The arguments are now available as environment variables, both lowercased and UPPERCASED (see Usage below)
