1 | # This defines a bash command named `edit' which contacts/resumes an |
| 2 | # existing emacs or starts a new one if none exists. | |
| 3 | # | |
| 4 | # One way or another, any arguments are passed to emacs to specify files | |
| 5 | # (provided you have loaded `resume.el'). | |
| 6 | # | |
| 7 | # This function assumes the emacs program is named `emacs' and is somewhere | |
| 8 | # in your load path. If either of these is not true, the most portable | |
| 9 | # (and convenient) thing to do is to make an alias called emacs which | |
| 177c0ea7 | 10 | # refers to the real program, e.g. |
| a933dad1 DL |
11 | # |
| 12 | # alias emacs=/usr/local/bin/gemacs | |
| 13 | # | |
