I wrote up a script to handle sessions for me. I typically use ssh
and a laptop so a multiplexer helps a lot, especially when updating
software, encoding videos, or anything else that takes a lot of time. I
haven't used tmux for very long, I just recently found it, so I don't
know if there's any quirks I'm not covering in the script. Maybe other
people can try it out and give suggestions?
#!/bin/sh
sessions=
# Check to see if tmux is running, or else sed might stall
tmux has-session 1>&2 2>/dev/null
if [ $? -eq 0 ]; then
sessions=`tmux list-sessions 2>/dev/null | sed -e 's/^\(.*\):
\(.*\)$/"\1" "\2" /' -e 's/(attached)/[attached]/' -e 's/(created.*)//' `
fi
# Get the terminal size, or default to 80x23 which is reasonable
ttysize=`stty size 2>/dev/null`
if [ $? -eq 0 ]; then
ttyw=`echo $ttysize|cut -f2 -d\ `
ttyh=`echo $ttysize|cut -f1 -d\ `
else
ttyw=80
ttyh=23
fi
# Clean up temp files when leaving
tmuxsm_rmf ()
{
rm -f $tmpfile
}
trap tmuxsm_rmf exit
tmpfile=`mktemp -t tmuxsm`
eval dialog --menu \"tmux Session Manager\" \
$(($ttyh - 4)) $(($ttyw - 9)) $(($ttyh - 11)) \
"New" \"Start a new session\" \
$sessions 2>$tmpfile
# User canceled, or something else happened
if [ $? -ne 0 ]; then
echo "Canceled 1"
exit 1
fi
result=`/bin/cat ${tmpfile}`
if [ "${result}" = "New" ]; then
tmuxsm_rmf
dialog --inputbox "Session Name" 8 $(($ttyw - 9)) 2>$tmpfile
# User canceled, or something else happened
if [ $? -ne 0 ]; then
exit 1
fi
result=`/bin/cat ${tmpfile}`
exec tmux new-session -s "${result}"
else
tmuxsm_rmf
exec tmux attach-session -t "${result}"
fi
