Hi all,
trying to make sense of the documentation on run:
https://docs.perl6.org/routine/run.
In particular the last part. I don't understand the adverbs :out and :
err there.
Can I set it up so that the output is piped into a file directly? If so
how would I write that?
I know I could use shell for that, but I doubt that is necessary.
[On first reading I found the doc confusing because it start with a
hairy example. WHy would anyone wish to write to a file named
'>foo.txt'? How can that be the first example?]
Thanks,
Hi Theo,
I wrote a module for "run" that may be useful. Let
me know if you want it. It looks like this:
( RtnStr, RtnCode ) = RunNoShell( "cat --number $MyDir" );
( RtnStr, RtnErr, RtnCode ) = RunNoShellErr( "cat --number $MyDir" );
It removes having to quote each parameter in the run string.
You just write it like you were in a command shell. The returned
error code ($? in bash) is really handy to have (0=true,
not 0 = false in bash).
It also shows what :out and :err are all about.
