I need to loop through the files in a directory and process the files. But some of the filenames contain spaces.
Here is a little test script I've been using to experiment. (I'm not really going to call 'echo', I'm doing some other processing.) Everything I try fails. How can I do this??... (7 Replies)
I want to ftp all the sh files in the directory. Also if any of the file name

Perl::Critic::Policy::InputOutput::ProhibitBacktickOperaUser(Contributed Perl DocPerl::Critic::Policy::InputOutput::ProhibitBacktickOperators(3pm)NAME
Perl::Critic::Policy::InputOutput::ProhibitBacktickOperators - Discourage stuff like "@files = `ls $directory`".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Backticks are super-convenient, especially for CGI programs, but I find that they make a lot of noise by filling up STDERR with messages
when they fail. I think its better to use IPC::Open3 to trap all the output and let the application decide what to do with it.
use IPC::Open3 'open3';
$SIG{CHLD} = 'IGNORE';
@output = `some_command`; #not ok
my ($writer, $reader, $err);
open3($writer, $reader, $err, 'some_command'); #ok;
@output = <$reader>; #Output here
@errors = <$err>; #Errors here, instead of the console
CONFIGURATION
Alternatively, if you do want to use backticks, you can restrict checks to void contexts by adding the following to your .perlcriticrc
file:
[InputOutput::ProhibitBacktickOperators]
only_in_void_context = 1
The purpose of backticks is to capture the output of an external command. Use of them in a void context is likely a bug. If the output
isn't actually required, "system()" should be used. Otherwise assign the result to a variable.
`some_command`; #not ok
$output = `some_command`; #ok
@output = `some_command`; #ok
NOTES
This policy also prohibits the generalized form of backticks seen as "qx{}".
See perlipc for more discussion on using "wait()" instead of "$SIG{CHLD} = 'IGNORE'".
You might consider using the "capture()" function from the IPC::System::Simple module for a safer way of doing what backticks do,
especially on Windows. The module also has a safe wrapper around "system()".
