I received an interesting support request recently regarding sending SMS via EirText using AppleScript. After mucking around with it for a few mins, it's actually quite easy to do:
For most accounts, the following will work:
do shell script "/Applications/EirText.app/Contents/MacOS/EirText -u086XXXXXXX -n O2.ie -r 086XXXXXXX -m "Message goes here.""
If you're using an account which has spaces or unusual characters in the name (e.g. "Three.ie (New Webtext)" is a tricky one), then you will need to double-escape those characters, as follows:
do shell script "/Applications/EirText.app/Contents/MacOS/EirText -u083XXXXXXX -n Three.ie (New Webtext) -r 083XXXXXXX -m "Messagegoes here.""
If you're scripting EirText in any cool or unusual ways, do let me know— I'd love to hear about it!
