sorry I dont have the use of nawk or grep with the -q switch
egrep -v wouldn't get what Im looking for as it wouldnt highlight any errors
sorry I only have limited knowledge of awk and sed so Im not sure how I would use them in this case
What I am looking for is by using grep or egrep or any other command to search though a file for expression1|expression2|expression3 etc... and if it can't find one of the expressions output an error along the lines of "can't find expression1". If it does find the expression in the file then do nothing and output nothing.
Thankyou for all your help so far people

SYNOPSIS
#include <disklabel.h>
DESCRIPTION
Disktab is a simple database which describes disk geometries and disk partition characteristics. It is used to initialize the disk label on
the disk. The format is patterned after the termcap(5) terminal data base. Entries in disktab consist of a number of `:'-separated fields.
The first field for each entry gives the names by which a disk's entry may be selected, separated by `|' characters. The last name given
should be a long name fully identifying the disk.
The optional fields for each entry are:
