Hello ripat,

Indeed it should be escaped.
but that kind of input is unlikely of course.

Linux :

Code:
 bash-2.03$ expr match singh@test.com '\(^[a-zA-Z0-9\w\.\_\-]*@[Tt][Ee][Ss][Tt].[Cc][Oo][Mm]$\)'
singh@test.com
bash-2.03$

Solaris :

Code:
bash-2.03$ expr match singh@test.com '\(^[a-zA-Z0-9\w\.\_\-]*@[Tt][Ee][Ss][Tt].[Cc][Oo][Mm]$\)'
bash-2.03$

The output in solaris is blank. Could anyone please let me know what changes can I make in this command to make it work.

Any suggestions would be greatly appreciated !!!

@ ygemici ... thanks for the reply ... though this will not give an exact match, see the below one

bash-2.03$ expr match singh@test.comtest '\([a-zA-Z0-9\w\.\_\-]*@[Tt][Ee][Ss][Tt].[Cc][Oo][Mm]\)'
singh@test.com
bash-2.03$

Hey Gaurav,

I guess S+ would allow only alphabets to be matched ... I need a regex which would allow a combination "-, _, ., alphabets and numerals" as input for email address.

$ echo 'singh@test.coms' | grep -qi '^[a-z0-9_-.]\+@test\.com$' && echo 'got match' || echo 'failed'

Hey Ripat,

Am getting following error while using grep command,

Code:
bash-2.03$ echo 'singh@test.com' | grep -qi '^[a-z0-9_-.]\+@test\.com$' && echo 'got a match' || echo 'failed'
grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .
failed
bash-2.03$

Code:
gaurav@localhost:~$ echo singh_.@test.com | perl -wln -e 'print if /^\S+\@test.com/i'
singh_.@test.com
gaurav@localhost:~$ echo singh##___.@test.com | perl -wln -e 'print if /^\S+\@test.com/i'
singh##___.@test.com
gaurav@localhost:~$

\S matches any non-space characters which includes dot,@,# or any special characters.

gaurav.
