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

Description
The command performs a series of tests on each filename argument in an attempt to classify it. If an argument appears to be ASCII, the
command examines the first 1024 bytes and tries to guess its language.
For character special files, part of this classification is information about which devices the system shows as active. In particular,
device-specific information such as controller type and unit, device type and unit, and status (offline, write locked, density, errors) is
returned. The general categories currently implemented are disk, tape, and terminal devices. The supported terminal devices include Local
Area Terminals (LAT) but not Local Area Network (LAN) pseudo-terminals.
The command uses the file to identify files that have some sort of magic number. A magic number is any numeric or string constant that
identifies the file containing the constant. Commentary at the beginning of explains its format.
Options-c Checks the magic file for format errors by printing the internal representation of the magic file. No file typing is done under -c.
-f Interprets the following argument to be a file containing the names of the files to be examined.
-m Instructs file to use an alternate magic file.
Restrictions
It often does a poor job of distinguishing C programs, shell scripts, English text, and ASCII text.
It does not recognize many programming languages, including Modula, Pascal, and Lisp.
