Now I want it to convert it into something. "wxyz_0019 wxyz_0314" "None" should be ignored. a 4 digit valid number should be used only. `echo $VAR |cut -d, -f2 can give one of them. The given string is not fix. It may be sometimes ",0019,0314,None,0416,0515" Then resulted string should be "wxyz_0019 wxyz_0314 wxyz_0416 wxyz_0515". I can do this quite easily in Perl. But i need to do this in Korn Shell. appreciate the response. thanks Sumit
