Well, hyphen (‘-’) may also mean stdin as expected, but it seems not

Interesting.
Recent versions of tar(1) on {Free,Net}BSD stipulate:
-f file, --file file
Read the archive from or write the archive to the specified file. The
filename can be - for standard input or standard output. The default
varies by system; on FreeBSD, the default is /dev/sa0; on Linux, the
default is /dev/st0.
I assume it's stdin when compressing and stdout when expanding. Or maybe
vice versa?

On my NetBSD VM, sh and ksh are two different executables. ENV points to
~/.shrc which then sources ./.kshrc if KSH_VERSION = true
I have though of replicating the same configuration over to OpenBSD but
I might be looking for trouble.
On a side note, there's no mention of startup files in sh(1) and I
wonder why.

What does the "#n" after "GENERIC.MP" stand for?
Hi, Out of curiosity: ~$ uname -r 6.6 ~$ uname -v GENERIC.MP#0 ~$ sysctl kern.osversion kern.osversion=GENERIC.MP#0 This was GENERIC.MP#7 before I ran syspatch and rebooted. I can't find a reference to this notation. I thought it could have been the patch version number, but it's obviously not so. Looking on: https://dmesgd.nycbug.org/index.cgi?do=index&fts=OpenBSD it appears machines running -current have a higher #number. -- Ottavio Caruso
How do I get the man page for a package I haven't installed yet?
Hi, Unless I've got it all wrong, <https://man.openbsd.org/> will only display man pages for programs and commands in base. Is there a way to display the man page for a package/port I haven't installed and/or downloaded yet? (This assumes I haven't downloaded the ports cvs tree).

How do I get a list of the files of only installed packages?
Hi, "pkg_info -L PACKAGE-NAME" will give me a list of all the files within each package, regardless of whether the package is installed or not. How can I restrict the output to only installed packages, making it fail if the package is not installed? I could do: "pkg_info -f PACKAGE-NAME " but that would not give me full pathnames. I've looked at the pkg_info man page but I couldn't find a clue. Thanks. -- Ottavio Caruso

These are interesting for their historical value, and in some cases (for example vi and the lpd tutorials) are somewhat still relevant.

There are gazillions of abandonware (badly) written for old versions of Windows (Win 3.* up to XP) that don't even run properly on Windows 10 but run beautifully on Wine.
