msc: stuff like pocket lint

MSC is my collection of missing shell commands - stuff where I feel comfortable when it's at my fingertips on a Unix commandline, and where I feel very naked when I don't have it! Have you ever been asked by a customer to take care of a Unix system, and then you log in, and.. aarrgh - the commandline just won't behave how it should? Well, enter msc: a set of "missing commands" that are very easily installed on new systems and very handy to have.

As with most stuff on my site: feel free to use MSC. It's distributed without cost, and without warranty - use at your own risk. Licensing GPLV3 applies: if you re-distribute it, you must do so in source format, and with the license intact. Finally - if you have good additions, you're of course free to put them in, but I'd appreciate a holler!

How to get it

What does it do

Here's a quick description of what's in the MSC package. The following list shows, in no particular order, the commands that you normally type (and not the setup-commands like shown in the listing above).

Full "usage" information

Here's what msc reports when you run it without any arguments:

  msc bootstrap [BINDIR] > /tmp/$$; . /tmp/$$; rm /tmp/$$

Available (symlinked) commands:
