You can press Ctrl-Alt-e to perform the readline function shell-expand-line
which will do alias, history and word expansions. Note that on some keyboards Meta is not Alt. You might need to press Esc then Ctrl-e
The functions alias-expand-line
and history-and-alias-expand-line
are not bound by default, but you can bind them by adding lines similar to the following to your ~/.inputrc
file.
"\e\C-l": alias-expand-line
which would make Ctrl-Alt-l (lower case "ell") perform only alias expansion.
