Question Issues with expr command on Solaris Box
Hello Friends,

I have written a code on a Linux box, however, am getting issues while running it on a Solaris server. The issue with Sed command is sortd out, however, am still lokking for solutions with expr command. Here is the issue,

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 !!!

You may want to try one of these perhaps.

Code:
gaurav@localhost:~$ echo singh@test.com | perl -wlp -e '/^\S+\@test.com/i'
singh@test.com

Test your i/ps with this . "-i" stands for case-insensitive. so it makes your regex less ugly. code your stuffs in perl if you want them portable would be my advise.

Regards,
Gaurav.

Don't have a solaris but try to use the comparison operator : instead of its alias.

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

Need to make exact match
Hi Gaurav,

Thanks for the suggestion. Am not familiar with Perl Scripting, however, now I am plannig to study it as well. Could you please let me know how can I make exact pattern match, for instance singh@test.coms should not be matched. (there is an extra "s" after com).

Why don't you try with grep:


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

> got a match



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

> failed

Hi. thats simple regex modification. put a "$" (end of line) after com. for example

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

Hope you get the point.
Regards,
Gaurav.

singh@test.com
gaurav@localhost:~$
[/code

This pattern /^\S+\@test.com$/i will match anybody@testscom. Shouldn't the dot be escaped?
