IBM How to use pipe operator as simple character in text file?

Hello all, I have two files which are cmd and disk.
Code:
`$cat cmd  
lsdev | grep -iw`

Code:
`$cat disk  
hdisk2`

Now I want to use the contents of both the files in a way such that
Code:
`lsdev | grep -iw`

command works for hdisk2 when I write the following script:

Code:
`!#/bin/sh  
cmd1="$( sed -n '1p' cmd)"  
disk1="$ (sed -n '1p' disk)"  
comm="$cmd1 $disk1"`
echo `$comm`

Now whenever I try to run the script, an error is thrown regarding wrong usage of | in lsdev command. Please help me find a solution for the same. Thanx

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
