How to extract the subject from a script which uses mailx
Hi,

I need to extract the subject of an e-mail sent using mailx. mailx is in a a file and the command reads like the following

Ex: sendMail.sh

mailx -s ' This is the subject' $recepiant

note that anything can come within ' ' which goes to the subject.

Please help

Looks like the source is not that clear. The subject can be wrapped with either ' ' or " " it seems. Anyway if i can extract whatever between "mailx -s" and "$recepiant" it should work. Please help
