I) Regarding your if statement, you could do something like this:

estr='FILE: %s does not exist or does not have %s permissions.\n'
[ -r $inputfile ] || ( printf "$estr" "$inputfile" "read" && exit 1 )
[ -w $outputfileNOM ] || ( printf "$estr" "$outputfileNOM" "write" && exit 1 )
[ -w $outputfilePGP ] || ( printf "$estr" "$outputfilePGP" "write" && exit 1 )

II)The -r/-w/-x mean that the file has the read/write/execute bit set. Do a

$ man chmod

for details.

III) You should be able to do

if [[ "$line" =~ .*\<NV\> ]]; then
	echo "..."
	(( countNOM++ ))
fi

but that didn't work for me when I tried it. I don't know if this is a bug in bash, or (more likely) something that I am doing wrong.

Regardless, I would write your script like this:

#!/bin/bash

file=$(egrep '^[A-Z]..[0-9]{2}' "$1")
grep '\<NV\>' <<< "$file" > "$2"
grep '\<PV\>' <<< "$file" > "$3"

echo 'Count NON:' $(wc -l < "$2")
echo 'Count PGP:' $(wc -l < "$3")

Note: In reading your script, your comments imply that each line of the input file starts with 'llnnn' but the example line you gave starts with 'lllnn'. That is, there are 3 letters (AVO) followed by 2 numbers (01). The above script assumes that lines start with 'lllnn'

exit isn't working because it's in a subshell started by ( ). What you want to use is { }, note that it needs to end in a ;

Compare:

( exit )
{ exit; }

Well, I originally wrote

[ -r $inputfile ] || { printf "$estr" "$inputfile" "read" && exit 1 }

but that didn't work for me, so I put it in () which did work. I have played around with it a little this morning and I got the following to work:

[ -r $inputfile ] || { printf "$estr" "$inputfile" "read" && exit 1; }

You need a ';' at the end (at least I did).

Edit: I see Procyon indicated the ';' at the end in his (her?) example. I guess I wasn't aware of that.

gromlok, I just read the bash FAQ you linked to, and I believe the following will work.

NOM='\<NV\>'
if [[ "$line" =~ $NOM ]]; then
	echo "..."
	(( countNOM++ ))
fi

They (the \< and \>) indicate that the 'NV' can't be contained in another word.
