I want to run a Perl script on multiple files, with same name ("Data.txt") but in different directories (eg : 2010_06_09_A/Data.txt, 2010_06_09_B/Data.txt).
I know how to run this perl script on files in the same directory like:
But my filenames are same, and they are in different directories. How to go about this?

.... <Shell script snipped> ...
a_programmer's shell for loop is far better.
Perl globbing example follows -
You can iterate through all files named "Data.txt" in the Perl program itself, thereby avoiding the shell's for loop.
Example of your Perl script "myscript.pl" -

Question for anyone that might be able to help:
My objective is to eheck if a file (a source file) exists in a directory. If it does then, I'd like to call an application (Informatica ETL file...not necessary to know) to run a program which extracts data and loads it into multiple targets.

I have a script that I need to run on one file at a time. Unfortunately using for i in F* or cat F* is not possible. When I run the script using that, it jumbles the files and they are out of order. Here is the script:
gawk '{count++; keyword = $1}
END {
for (k in count)
{if (count == 2)... (18 Replies)
Hi All,
I would like to use a Perl (not Bash) script to work with multiple files of the same name in different directories (all in the same parent directory). I tried to create a loop to do so, but it isn't working.

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.
