I want to create an alias in bash
like this:
alias tail_ls="ls -l $1 | tail"
Thus, if somebody types:
tail_ls /etc/
it will only show the last 10 files in the directory.
But $1
does not seem to work for me. Is there any way I can introduce variables in bash.

I'd create a function for that, rather than alias, and then exported it, like this:
function tail_ls { ls -l "$1" | tail; }
export -f tail_ls
Note -f
switch to export
: it tells it that you are exporting a function. Put this in your .bashrc
and you are good to go.
