I wouldn’t install a program for this if your use case is simple. You will end up relying on it when there are already some built in tools that can get you 99% of the way there.

1. Bash scripts placed in ~/bin or ~/.local/bin

• Can have simple or complex scripts setup to do whatever you want
• Easily called from terminal or automated through cron or systemd

2. Environment variables set in -/.bashrc

• Great for storing common paths, strings, etc.
• Can be easily incorporated into bash scripts

3. Aliases set in ~/.bashrc

• Ideal (IMO) for common commands with preferred options
• for example you could setup your most used rsync command to an alias: alias rsync-cust=“rsync -avuP”

Edit: rephrased to not discount the tools shared. I am sure if you had a specific reason to use them they could be helpful. But I think for many users the above options are more than enough and are supported pretty universally.
