Hi Sumit,
Depending on your version of sed, you can probably use :
sed with BRE (Basic Regular Expressions
echo ",john,0019,0314,None,0416,0515,junk" | sed
's/\([^0-9]*\)\([0-9]\{4\}\)\([^0-9]*\)/wxyz_\2 /g'
OR sed with Extended Regular Expressions
For Linux :
echo ",john,0019,0314,None,0416,0515,junk" | sed -r
's/([^0-9]*)([0-9]{4})([^0-9]*)/wxyz_\2
/g'
For BSD :
echo ",john,0019,0314,None,0416,0515,junk" | sed
-E's/([^0-9]*)([0-9]{4})([^0-9]*)/wxyz_\2 /g'
Please let us know if this works or if you need to extend this.
Thanks!
John
