Selective grep
I have to grep out only email address from a column. It has characters appended and prepended Code:
F=<sss1@domain.com> <sss2@domain.com> (sss3@domain.com) <sss4@domain.com> Whatever added before and after email, I should be able to grep out only emails. |

A slight extension to guruprasadpr's solution: Code:
grep -Eo '[[:alnum:]]*@[[:alpha:]]*(\.[a-z]{2,4})+' file |
