From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This command is awkward 'docket exec -t vaultwarden sh' , let's just have docker sh vaultwarden already ! (lemmy.ml)

I thought this would be hard, but turns out the following oneliner does it, with maybe no sideeffects ?

echo 'docker() { [ "$1" = "sh" ] && docker exec -it "$2" sh || command docker "$@"; }' >> ~/.bashrc && source ~/.bashrc

This creates a bash alias for "docker ps" , every other command should run as normal

Now I just need to remember to run this one liner on every single computer I use in the future...

dit="docker exec -it $@"

Seems more flexible to me. Also, you shouldn't give functions or variables the same names as binaries.

The "$@" doesn't do that you think it does in an alias. It gets expanded on alias creation.
