Re: Backtics execution with multiple lines

It's not the backticks that interpret it as two commands, but your shell. This works for me:

$ cat foo.pl
print ` echo foo \\
bar`;
$ perl foo.pl
foo bar

That's curious, becouse I can do command line splitting with "\" in my shell. And here backticks are not working: $ cat backticks.pl #!/usr/bin/perl `ls \ -l *.pl`; $ perl backticks.pl sh: line 1: -l: command not found [download]	[reply] [d/l]

Backticks interpolate, so you have to escape your `\` character: thus `\\`. String interpolation.	[reply] [d/l] [select]

You're not passing a slash to the shell. Backticks are like `""`. If you want the resulting string to contain a slash, you need to escape it. `$ perl -le'print "foo bar"' foo bar $ perl -le'print "foo\ bar"' foo bar $ perl -le'print "foo\\ bar"' foo\ bar` [download]	[reply] [d/l] [select]
