I use the following, which I call '$HOME/bin/e'. I use it as follows:
$ e # opens a window
$ e foo.sh # opens an old or new file
$ e foo.sh:23 # opens foo.sh at line 23
I never have to think if emacs is already loaded or not. Hope it
helps.
#!/bin/sh
EMACS=emacs
if [ -z "$DISPLAY" ]
then
$EMACS ${1+"$@"}
else
if emacsclient --eval "(setenv \"DISPLAY\" \"$DISPLAY\")" >/dev/null 2>&1;
then
if [ $# -eq 0 ]; then
emacsclient --eval "(make-frame-on-display \"$DISPLAY\")"
elif [ $# -lt 10 ]; then
for f in $@; do
# handle file.h:234 paths
echo $f | egrep ".*:[0-9]+$" >/dev/null
if [ $? -eq 0 ]; then
emacsclient -n `echo $f | sed 's/\(.*\):\([0-9]\+\)$/+\2/'`
`echo $f | sed 's/\(.*\):\([0-9]\+\)$/\1/'`
else
emacsclient -n $f
