how can I tell how many Terminal windows (in mac os x) are currently opened? this needs to be done from a shell script.
thanks,
This script does what you ask for, you use osascript
to run it from the cmd line.
tell application "Terminal"
set c to 0
repeat with i from 1 to (count of windows)
set c to c + (count of tabs in window i)
end repeat
c
end tell
Edit by Bavarious: In order to use Adam's AppleScript inside a shell script, you can do the following:
#!/bin/bash
read -d '' OSASCRIPT << EOF
tell application "Terminal"
set c to 0
repeat with i from 1 to (count of windows)
set c to c + (count of tabs in window i)
end repeat
c
end tell
EOF
nwindows=$(osascript -e "${OSASCRIPT}")
cnt=$(w -h | grep "^$(whoami) *s[^ ]* *-"|wc -l)
echo Your current terminal sessions: $cnt
