(I mean by using that ...
I loath working on the command line in Windows, primarily because the terminal application is wretched to use compared to terminal applications on linux and OS X. Major complaints No standard copy/paste. You have to turn on "mark" mode and it's only available from a multi-level popup triggered by the (small) left hand corner button. ...

Would curl be an option, so I also can count the errors and successes? [Update] I guess I have not explained it enough. What I want to do is have one file which I can call like from http...
I'm processing a huge file with (GNU) awk, (other available tools are: Linux shell tools, some old (>5.0) version of Perl, but can't install modules).

I've found the "open" command in Mac OS X very handy in the command line. From "man open": The open command opens a file (or a directory or URL), just as if you had double-clicked the file's icon. If no application name is specified, the default application as determined via LaunchServices is used to open the specified files. That is,...
