Top Forums Shell Programming and Scripting how to invoke external program and capture its output Post 302681489 by Corona688 on Friday 3rd of August 2012 12:45:03 PM

Running 30,000 individual, separate shells to run 30,000 commands is wrong, period. That's like making 300 phonecalls to say 300 words. You never have to do that, even if you're processing the result in perl. There's also some useless use of backticks in there, though seeing it in perl is a first.

You could do the loop in shell and feed the result into perl through files or stdin, perhaps.

I don't know why it's taking 80 as a command. It shouldn't be, unless there's odd unprintable characters there which convince it it's on a different line. Or maybe a ; Did you copy-paste the code literally or is it slightly different from what you posted?

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 package require uri::urn ?1.1.2? uri::urn::quote url uri::urn::unquote url _________________________________________________________________ DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to handle urls using the urn scheme. COMMANDS
uri::urn::quote url This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its result. uri::urn::unquote url This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters, and returns the modified urls as its result.
