grep searching
I am making a script but having little problem. at one part I need to find one number format or other format from a file..
those formats are xxx-xx-xxxx or xxxxxxxxx
i tried
Code:
grep '( [0-9]\{3\}-[0-9]\{2\}-[0-9]\{3\} |[0-9]\{9\})'

if i do them sepratly it work but like this it is not working
Please check what the problem is with this code

How about this...
Code:
grep  -E '[0-9]{3}-[0-9]{2}-[0-9]{3}|[0-9]{9}'

-E(or just use egrep) which is for extended regular expression, read the man page for grep

i tried but it's not working. when i use egrep or grep -E it does not return anything.
The problem is like this.
Code:
some command | some command | some command | grep -E  '( [0-9]\{3\}-[0-9]\{2\}-[0-9]\{3\} |[0-9]\{9\})'

This does not return anything

but if i do separately then both works
Code:
some command | some command | some command | grep  '( [0-9]\{3\}-[0-9]\{2\}-[0-9]\{3\} '

Code:
some command | some command | some command | grep [0-9]\{9\})'

Your system's grep doesn't support -E, please replace by egrep.

Code:
some command | some command | some command | egrep  '( [0-9]\{3\}-[0-9]\{2\}-[0-9]\{3\} |[0-9]\{9\})'

Do you try malcomex999's command? (They are different with yours.)

Code:
grep  -E '[0-9]{3}-[0-9]{2}-[0-9]{3}|[0-9]{9}'

egrep '[0-9]{3}-[0-9]{2}-[0-9]{3}|[0-9]{9}'

Thank you for figuring that out...the problem was, I was using same [0-9]\{3\} but the way he use [0-9] {3} works fine.. thanks
