I made an echo command to my .bash_aliases file and erased all of my aliases, except the test alias. However, I still have a session open that has the aliases loaded (into the tcl?). Can I retrieve them from this session?

Easy trick

for alias in $(compgen -a); do type $alias; done

    Combine this with redirection to a file ($alias > .bash_aliases, maybe with some file regexes to get it to the right place in the file) and you don't have to type it back into the original file yourself. (That is, if you haven't already typed it in.)

    While this works, I don't see the benefit over just using 'alias'. The format isn't particularly useful by comparison.

You can almost definitely just do:

alias >>./bash_aliases
