Re: Line breaks within backticks

This solution allows indentation and "syntactically" is still one statement

lhp@nereida:~/Lperl/src/testing$ cat -n qx.pl
     1  print (
     2    $c = 'ls -l '.
     3          join(' ', qw{
     4                       context1.pl
     5                       decomposed_char_utf8_2.pl
     6                       file1.txt
     7                       es.log}
     8          )
     9    and qx{$c}
    10  );

substitute join ' ' by join '' to assume the restriction that spaces aren't allowed between args.

Better yet, use the multiple argument form to avoid (lack of) escaping problems and to simplify the code. `my @cmd = ( 'ls', '-l', 'file1', 'file2', 'file with space', ); my $results = do { open(my $fh, '-\|', @cmd) or die("Unable to run $cmd[0]: $!\n"); local $/; <$fh> };` [download] PS - Why did you use `and` there instead of making two statements?! Update: Fixed wrong variable name.	[reply] [d/l] [select]

Nice solution, but it turns into even more code, which kind of negates the point. :)	[reply]
