I added a line to my .bashrc ages ago and I can't remember what I was trying to achieve. The line is:
bat () { echo "$(<"$@")" ; }
Now I've installed a different Linux distro and when I run it, I get the error:
bash: "$@": ambiguous redirect
Can anyone help me understand what I might have intended with this?

Looks like you were trying to implement `cat` using just Bash builtins! However, your function only accepts one argument. If you want to handle multiple files, you’d need to use a loop like this:
bat() { local f; for f in "$@"; do echo "$(<"$f")"; done; }
It seems like you were trying to create a version of `cat` that can handle multiple files, but it didn’t really work out as expected. Your function only processes one filename at a time, which is why you're running into that error when you try to pass multiple arguments.
