Yes it is a loop. Basically, the bashloops through dir, which may have 3 files in it, but the oldest $filename in dir is returned by the bash. That is the variable I am trying to store in $filename.
So, if the 3 files were
Code:
123.txt
456.txt
789.txt
123.txt would be stored in $filename because that is the oldest. Thank you very much .
In a shell script, I am storing some values into variables. In between the code I am calling an PL/SQL precedure by connecting to ORACLE which generates a file. All this happens fine.
The problem is, the values are not getting stored in variables after this PL/SQL code while perfectly before... (1 Reply)

Hi,
I'm trying to search a text file for a string: "energy(sigma->0)=". To do so, I executed the grep command, which returned many matches, for example:

energy without entropy = -112.16488936 ... (5 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.
