Subject: Add a "screen" subcommand to krbroot
X-Git-Url: https://www.dehnerts.com/gitweb/?p=user%2Falex%2Fsoftware%2Fmy-snippets.git;a=commitdiff_plain;h=aa6f780a758a977cdcecee9ff45b3f428440a1b0

Add a "screen" subcommand to krbroot

I have screen profiles for "all scripts web servers", "all scripts hosts",
etc., which means I often want to run screen with root tickets and pass it some
options. This makes that easy.

This uses the technique from ASA DB commit
08d4fa6744d2785023666d10a1936460811fcdb2
(https://asa.scripts.mit.edu/trac/changeset/08d4fa6744d2785023666d10a1936460811fcdb2)
to pass commands possibly containing metacharacters through pagsh without
quoting issues.
