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` [download]	[reply] [d/l] [select]
