I'm new to AWK and I'm having problems comparing a field to a string variable.
My code tries to find a record with the string "ARTIST". Once it finds it, it stores the second field of the record into a variable. I don't know what the problem is for the second line. The point is if the first field of a record matches the variable, it will print the entire record. But for some reason, it's not working.

cap_mkdb
CAP_MKDB(1) BSD General Commands Manual CAP_MKDB(1)NAME
cap_mkdb -- create capability database
SYNOPSIS
cap_mkdb [-v] [-f outfile] file1 [file2 ...]
DESCRIPTION
Cap_mkdb builds a hashed database out of the getcap(3) logical database constructed by the concatenation of the specified files .
The database is named by the basename of the first file argument and the string ``.db''. The getcap(3) routines can access the database in
this form much more quickly than they can the original text file(s).
The ``tc'' capabilities of the records are expanded before the record is stored into the database.
The options as as follows:
-f outfile
Specify a different database basename.
-v Print out the number of capability records in the database.
FORMAT
Each record is stored in the database using two different types of keys.
The first type is a key which consists of the first capability of the record (not including the trailing colon (``:'')) with a data field
consisting of a special byte followed by the rest of the record. The special byte is either a 0 or 1, where a 0 means that the record is
okay, and a 1 means that there was a ``tc'' capability in the record that couldn't be expanded.
The second type is a key which consists of one of the names from the first capability of the record with a data field consisting a special
byte followed by the the first capability of the record. The special byte is a 2.
In normal operation names are looked up in the database, resulting in a key/data pair of the second type. The data field of this key/data
pair is used to look up a key/data pair of the first type which has the real data associated with the name.
RETURN VALUE
The cap_mkdb utility exits 0 on success and >0 if an error occurs.
