That's because you don't know what you're talking about.

    You're right. Don't know what I did before. deleting...

    $ perl -e "$now = localtime(); print $now;" syntax error at -e line 1, near "=" Execution of -e aborted due to compilation errors.

    As explained to me by ikegami and runrig in the chatterbox: perl -e "$now = localtime(); print $now;" and perl -e ' = localtime(); print ;' are equivalent in bash (Ubuntu's default) unless $now is an Environmental variable within the Bash shell.

    In other words if one is doing some Bash scripting and has defined $1 as a variable within that shell-script ... then the way to access that same system (environmental) $1 is to use perl -e " ... $1 ... ".

    Cheers.

      bash does support double quotes, but «\», «"» and «$» (and maybe more) are special in double quotes.

      $ perl -E'my $x = qq{abc\\def}; say $x' abc\def $ perl -E"my \$x = qq{abc\\\\def}; say \$x" abc\def
      On guard perl -le print~~localtime
        ~~? Can you provide a reference please?
