Trim a file columnwise
Hi All,

I want to trim each columns leading & trailing (like sql trim function) of a ',' separated file..

I've a file like this..

Code:
 manab , c  gi
   lucky , home 
 babu , maa

I want the output as

Code:
manab,c gi
lucky,home 
babu,maa

A one liner would be a great help.

Thanks itkamaraj, this has worked. I've added another expression & made it complete.
Code:
sed 's/^ *//g;s/ *,/,/g;s/, */,/g;s/ *$//g' <filename>

Thank You,
Manab
