Chubler_XL ,

Thanks for response.

I am trying this:
Code:
#!/usr/bin/ksh
awk -v lengths=10,4,10 '
BEGIN { FS = ","  ; OFS = ","
        split(lengths,len,FS)
      }
      { n = 0
        while ( ++n <= NF ) $n = substr($n,1,len[n])
        print
      }' File

It works good but when I have input as:
Code:
Id,Text,File
"123","Th
is is unix file","Unix"

Its Giving:
Code:
Id,Text,File
"123","Th
is is unix

Its not accepting the new line when it comes in middle of the field.

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
