However, the same directory has the installation instructions included, which is also a txt file: install.txt
I currently have the install.txt file renamed to install._txt, but I prefer a solution using regular expressions.
Is there an elegant way to exclude the install.txt from being concatenated as well?
Quick question,
File A has one line (10 charachters), File B has one line (10 charachters).
how do a concat these two files together to produce a file (File C) that has the contents of Files A + B together onto one line of 20 Charachters
if I use:
cat FileA FileB > FileC
I get the... (5 Replies)

I am new to Linux and I am trying to cat only N files in a folder. N is dynamically given number at runtime.
If I give N as 2 then cat only 2 files in the folder
and If I give N as 5 then cat only 5 files in the folder.
Is there any way to do that? (6 Replies)
Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3)User Contributed Perl DocumentatioPerl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3)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.
