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
