Bug 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?

NAME
git-column - Display data in columns SYNOPSIS
git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>] [--indent=<string>] [--nl=<string>] [--padding=<n>] DESCRIPTION
This command formats its input into multiple columns. OPTIONS
--command=<name> Look up layout mode using configuration variable column.<name> and column.ui. --mode=<mode> Specify layout mode. See configuration variable column.ui for option syntax. --raw-mode=<n> Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode. --width=<width> Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so. --indent=<string> String to be printed at the beginning of each line. --nl=<N> String to be printed at the end of each line, including newline character. --padding=<N> The number of spaces between columns. One space by default. GIT
