How so? Can you please give an example? Because they both invoke the shell? See https://metacpan.org/pod/perlipc#Safe-Pipe-Opens	[reply]

See also open which gives an example as `open(FOO, "\|cat -n \| expand -4 \| lpr")` perl isn't interpreting all those pipes, just the first one, the rest are given to the shell	[reply] [d/l]
