The problem is I get an error that the ${id}.txt does not exist. I have tried "${id}.txt as well. There is a file (attached) with the id in it as well but can sed or awk be used to extract this id from the file and put it in the perl command?
For example, snp.txt is the first line of target.txt - can that value be extracted and substituted for the ${id).txt in the perl . Also, if there are multiple lines can it loop through one at a time? Thank you .

I am fiddling with a little script that will issue a shutdown command if the temperature on the CPU goes above a certain level. I started writing the script in Bash, and then thought I would like to use Perl to extract the detailed bits, but I am not sure if this is really practical. Basically I... (2 Replies)

Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3pUser Contributed Perl DocumentatPerl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3pm)NAME
Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen - Write "open $fh, q{<}, $filename;" instead of "open $fh, "<$filename";".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The three-argument form of "open" (introduced in Perl 5.6) prevents subtle bugs that occur when the filename starts with funny characters
like '>' or '<'. The IO::File module provides a nice object-oriented interface to filehandles, which I think is more elegant anyway.
open( $fh, '>output.txt' ); # not ok
open( $fh, q{>}, 'output.txt' ); # ok
use IO::File;
my $fh = IO::File->new( 'output.txt', q{>} ); # even better!
It's also more explicitly clear to define the input mode of the file, as in the difference between these two:
open( $fh, 'foo.txt' ); # BAD: Reader must think what default mode is
open( $fh, '<', 'foo.txt' ); # GOOD: Reader can see open mode
This policy will not complain if the file explicitly states that it is compatible with a version of perl prior to 5.6 via an include
statement, e.g. by having "require 5.005" in it.
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
There are two cases in which you are forced to use the two-argument form of open. When re-opening STDIN, STDOUT, or STDERR, and when doing
a safe pipe open, as described in perlipc.
