Running command with backslash not working as expected

[nysus]

So running this command gives the desire result in the output file:

$_vim_cmd = '/usr/local/bin/vim';
`$_vim_cmd  . ' -c "normal \r" -c wq ~/vimwiki/testing.md'`;

This, however, does not:

$_vim_cmd = '/usr/local/bin/vim';
my $value = ' -c "normal \r" -c wq ~/vimwiki/testing.md';
`$_vim_cmd  $value`;

The \r is not getting processed. I tried escaping it: \\r and I tried \Q and I tried qx() but nothing does the trick.

This also works but is far from ideal, obviously:

    my $c1 = ' -c "normal ';
    my $c3 = '" -c wq ~/vimwiki/testing.md';
    `$_vim_cmd $c1\r$c3`;
