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.	[reply] [d/l] [select]

`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]
