Parse file and copy value to variable in sh script.
Hi,

I need to parse a simple text file like below and store the word that starts with BR* to a variable say $BRno. I need to do this in sh script.

NOTE: the length of the numbers following BR is not constant (eg: it could be BR1234 or BR22233). And there is only 1 BRxxxxx in a file at a given time.

.txt file:

BR276828
Apple
Orange
CHERRY
test.txt

Gurus, Please help as soon as you can !

Thanks !

*************************
This is not a homework. I am working on a few automation scripts at work. My manager just added a few simple requirements at the last minute today. This is one of them. And I need to roll-out the scripts tomorrow. I need to get a return value from a perl script to a sh script(calling the perl script from here). So I was tyring this method for that: copying the output of the perl script to a file, and trying to parse that file from the sh script to get the BRXXX to a variable that I will print out.

This is all probably confusing, that's why I simply just asked what I need without the background. Sorry about that !

Thanks fo any help !

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

       -r realm, --realm=realm
