Extract data from two files and create another 2

[pdtak]

I have two files that contains just file names.
The first files has the nfs mount points (ie. /mnt, /nfs1, etc.)
Second file has long file names (ie. /usr/bin/perl, /nfs1/file1, etc.)
I want the third file to contain only the non-nfs mounted files.

Example:

file1:
/mnt
/nfs1
/nfs2

file2:
/usr/bin/perl
/mnt/file1
/nfs1/file2
/etc/file3
/usr/bin/ls
/home/abc
/nfs2/file5

file3:
/usr/bin/perl
/etc/file3
/usr/bin/ls
/home/abc

Thanks in advance.

$> awk '!/mnt|nfs/ {print}' file1 file2 >> file3
$> cat file3
/usr/bin/perl
/etc/file3
/usr/bin/ls
/home/abc

Hi

I think pdtak wants something like this :

awk 'FNR==NR{m[NR]=$0;next}{for(i in m)if($0~"^"m[i])next}1' file1 file2 > file3

[gray]# or[/gray]

awk -F / 'FNR==NR{m[$2]=1;next}!($2 in m)' file1 file2 > file3

Tested with [tt]gawk[/tt] and [tt]mawk[/tt].

Looking at it again yes, you're right. Something like grep -vf ... but with awk.

Thank you both for your input.
I'll incorporate them into my script and see which works better.
