Sometimes you need to edit a file on a remote server, but using vim/emacs is not very practical, due to lag and speed of screen refresh.
TextMate users have the classic rmate, but it was implemented in Ruby, which may not be available on the remote server.
A better option is to use this version of rmate, implemented in pure Bash. It's a single file, self-contained, and with no external dependencies.
