I have another file, file2.txt, that contains only the strings in field 3 ($3), stripped of all characters beside [A-Z<>] due to the abundance of metacharacters in $3 (e.g., literal "[" and "/").
File2.txt contents:
Code:
TWRH
HGJ
JWMM
W
LJLH
W
HJJ
My goal is to print lines from file1.txt that do not have strings in $2 that contain the strings from file2.txt as follows:
I've attempted to accomplish this with the following bit of awk code:
Code:
awk 'BEGIN { while(getline l < "file2.txt") PATS[l] } ok=0;{for (p in PATS) if ($2 ~ p) ok=1}; !ok {print}' < file1.txt
I've used code similar to this on other files of mine where I needed to execute a similar function. However, this is returning no output whatsoever and cannot seem to pinpoint the problem here.
I would be very much appreciative of a solution that uses the two file approach I've described above or indeed, one that acts upon file1.txt using $3 as regex that are to be not matched by the strings in $2. Something of the sort:
You could also try this slight simplification of Aia's suggestion:
Code:
awk -F'"' 'FNR==NR{a[$1]; next} !($2 in a)' File2.txt file1.txt
Note that your code uses the filenames file1.txt and file2.txt, but your description says that the second file is named File2.txt. The code above uses the filenames given in the description of your problem and produces the output you said you wanted.
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

I cannot seem to get what should be a simple awk one-liner to work correctly and cannot figure out why. I would like to use patterns from a specific field in one file as regex to search for matching strings in the entire line ($0) of another file.
