The output of ``uname -a'' appears in hundreds of e-mails and PRs yet
the output format is not ideal for this (especially e-mail in
80-column mail readers) as it is a single line.
Attached is a patch for an enhancement I've made that adds a new
option ``-A'' (rather than change ``-a'') that splits it up into 3
lines thus making it better for including verbatim in e-mails and PRs:
# uname -A
FreeBSD parish 4.1-STABLE FreeBSD 4.1-STABLE #0:
Tue Aug 8 00:51:02 BST 2000
mark@parish:/usr/src/sys/compile/PARISH i386
The only thing I couldn't work out is why sysctl() adds 5 spaces after
the date sub-string, so I've haven't stripped them out (hence the
indented third line).
Is there any reason why this is unacceptable and could not be committed?
BTW, please Cc: me.
Thanks for your time.
