Hi nubie2linux,
Welcome to the UNIX & Linux Forums.

Your use of CODE tags is fine (and appreciated).

You haven't said what operating system (although we might guess that it is some Linux distribution from your choice of user name) or shell you're using... With a POSIX conforming shell (such as ksh [which is used in the examples below] or bash) and sed utility you could use something like:
Code:
#!/bin/ksh
while IFR= read -r part
do	sed "s/partition_name/$part/" insert.txt  > "insert_$part.txt"
done < partition_list.txt

Or, more efficiently, but requiring a little more typing, with awk:
Code:
#!/bin/ksh
awk '
FNR == NR {
	template = template RS $0
	next
}
{	out = substr(template, 2)
	file = "insert_" $0 ".txt"
	gsub(/partition_name/, $0, out)
	print out > file
	close(file)
}' insert.txt partition_list.txt

If you want to use awk on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

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/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/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

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

FILES

       /etc/shells	       lists shells on system
