If $1 in file1 matches $2 in file2. Then the value in $2 of file2 is updated to $1"."$2 of file2. The awk seems to only match the two files but not update. Thank you :).

I am trying to match $1 in file1 with $2 in file2. If a match is found then $3 and $4 of file2 are copied to file1. Both files are tab-delimeted and I am getting a syntax error and would also like to update file1 in-place without creating a new file, but am not sure how. Thank you :).

In the bash below the unique headers of each vcf.gz are stored in a text file with the same name. That is if 16-0000-file.vcf.gz was used the header text file would be 16-0000-file_header.txt.

path::dispatcher::rule
Path::Dispatcher::Rule(3pm) User Contributed Perl Documentation Path::Dispatcher::Rule(3pm)
NAME
Path::Dispatcher::Rule - predicate and codeblock
SYNOPSIS
my $rule = Path::Dispatcher::Rule::Regex->new(
regex => qr/^quit/,
block => sub { die "Program terminated by user.
" },
);
$rule->match("die"); # undef, because "die" !~ /^quit/
my $match = $rule->match("quit"); # creates a Path::Dispatcher::Match
$match->run; # exits the program
DESCRIPTION
A rule has a predicate and an optional codeblock. Rules can be matched (which checks the predicate against the path) and they can be ran
(which invokes the codeblock).
This class is not meant to be instantiated directly, because there is no predicate matching function. Instead use one of the subclasses
such as Path::Dispatcher::Rule::Tokens.
ATTRIBUTES
block
An optional block of code to be run. Please use the "run" method instead of invoking this attribute directly.
prefix
A boolean indicating whether this rule can match a prefix of a path. If false, then the predicate must match the entire path. One use-case
is that you may want a catch-all rule that matches anything beginning with the token "ticket". The unmatched, latter part of the path will
be available in the match object.
METHODS
match path -> match
Takes a path and returns a Path::Dispatcher::Match object if it matched the predicate, otherwise "undef". The match object contains
information about the match, such as the results (e.g. for regex, a list of the captured variables), the "leftover" path if "prefix"
matching was used, etc.
run
Runs the rule's codeblock. If none is present, it throws an exception.
