# This defines a bash command named `edit' which contacts/resumes an
|
||
|
|
# existing emacs or starts a new one if none exists.
|
||
|
|
#
|
||
|
|
# One way or another, any arguments are passed to emacs to specify files
|
||
|
|
# (provided you have loaded `resume.el').
|
||
|
|
#
|
||
|
|
# This function assumes the emacs program is named `emacs' and is somewhere
|
||
|
|
# in your load path. If either of these is not true, the most portable
|
||
|
|
# (and convenient) thing to do is to make an alias called emacs which
|
||
|
|
# refers to the real program, e.g.
|
||
|
|
#
|
||
|
|
# alias emacs=/usr/local/bin/gemacs
