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 $now;" syntax error at -e line 1, near "=" Execution of -e aborted due to compilation errors. [download] As explained to me by ikegami and runrig in the chatterbox: perl -e "$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
