Thanks for the response.
Thanks very much for your response.
Can you please clear my question below?
I tried the below perl one-line commands but I could not get feel the result as expected.
echo "One 1\nTwo 2\nThree 3" | perl -ne 'print if m/^Two (\d+)$/m'
echo "One 1\nTwo 2\nThree 3" | perl -ne 'print if /(?m)^Two (\d+)$/'
But I got a result as expected when I executed the .pl file the same. Please find the file below.
#!/usr/bin/perl
$inputstring="One 1\nTwo 2\nThree 3";
if ( $inputstring =~ /^Two (\d+)$/m )
{
print "Matching\n";
}
Can you please tell why the perl one-line command has not given the output?

PERLIVP(1) Perl Programmers Reference Guide PERLIVP(1)
NAME
perlivp - Perl Installation Verification Procedure
SYNOPSIS
perlivp [-a] [-p] [-v] [-h]
DESCRIPTION
The perlivp program is set up at Perl source code build time to test the Perl version it was built under. It can be used after running:
make install
(or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly. A correct installation is
verified by output that looks like:
ok 1
ok 2
etc.
OPTIONS
-h help
Prints out a brief help message.
-a run all tests
Normally tests for optional features are skipped. With -a all tests are executed.
-p print preface
Gives a description of each test prior to performing it.
-v verbose
Gives more detailed information about each test, after it has been performed. Note that any failed tests ought to print out some
extra information whether or not -v is thrown.
DIAGNOSTICS
o print "# Perl binary `$perlpath' does not appear executable.
";
Likely to occur for a perl binary that was not properly installed. Correct by conducting a proper installation.
o print "# Perl version `$]' installed, expected $ivp_VERSION.
";
Likely to occur for a perl that was not properly installed. Correct by conducting a proper installation.
o print "# Perl @INC directory `$_' does not appear to exist.
";
Likely to occur for a perl library tree that was not properly installed. Correct by conducting a proper installation.
o print "# Needed module `$_' does not appear to be properly installed.
";
One of the two modules that is used by perlivp was not present in the installation. This is a serious error since it adversely affects
perlivp's ability to function. You may be able to correct this by performing a proper perl installation.
o print "# Required module `$_' does not appear to be properly installed.
";
An attempt to "eval "require $module"" failed, even though the list of extensions indicated that it should succeed. Correct by
conducting a proper installation.
o print "# Unnecessary module `bLuRfle' appears to be installed.
";
This test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval " require
"$module_name.pm"; "" test may give misleading results with your installation of perl. If yours is the latter case then please let
the author know.
o print "# file",+($#missing == 0) ? '' : 's'," missing from installation:
";
One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation. Correct by
conducting a proper installation.
o print "# Perl header `$_' does not appear to be properly installed.
";
Correct by running h2ph over your system's C header files. If necessary, edit the resulting *.ph files to eliminate perl syntax
errors.
For further information on how to conduct a proper installation consult the INSTALL file that comes with the perl source and the README
file for your platform.
