# This script starts emacs daemon if it is not running, opens whatever file
|
|
# you pass in and changes the focus to emacs. Without any arguments, it just
|
|
# opens the current buffer or *scratch* if nothing else is open. The following
|
|
# example will open ~/.bashrc
|
|
|
|
# ec ~/.bashrc
|
|
|
|
# You can also pass it multiple files, it will open them all. Unbury-buffer
|
|
# will cycle through those files in order
|
|

|
# The compliment to the script is et, which opens emacs in the terminal
|
|
# attached to a daemon
|

# If you want to execute elisp, pass in -e whatever.

# You may also want to stop the output from returning to the terminal, like

# ec -e "(message \"Hello\")" > /dev/null
