Actually, it is not even possible to implement it as a stand-alone command because the effect of the intended change would end when the command exits. > When I am trying, I get the manual to cd (ATAPI and SCSI CD-ROM driver) > instead. > > It's the same with: man cd > > and in: https://man.openbsd.org/cd In general, when man(1) gives you the wrong section, specify the section: $ man 1 cd https://man.openbsd.org/cd.1 Of course, in the specific case at hand, that won't help because no such manual exists. Your next try if a manual you are looking for does not exist should be something like $ man -k any~^cd\$ See apropos(1) for details what "any", ~, ^, and $ mean. That gives you about a dozen results, and the shell manuals you are looking for are among them. If you want less noise, you can guess that cd is probably some kind of command, so a more specific try would be schwarze@isnote $ man -k Ic,Cm~^cd\$ csh(1) - a shell (command interpreter) with C-like syntax ftp(1) - Internet file transfer program help(1) - help for new users and administrators ksh, rksh(1) - public domain Korn shell mail, Mail, mailx(1) - send and receive mail sftp(1) - secure file transfer program sh(1) - command language interpreter vi, ex, view(1) - text editors azalia(4) - generic High Definition Audio device fsdb(8) - FFS debugging/editing tool restore, rrestore(8) - restore files or file systems from backups... You see, almost no false positives are left - ftp(1), sftp(1), restore(1), and even vi(1) indeed have internal cd commands, too. If you are completely desperate, you can even say $ man -ak Ic,Cm~^cd\$ to get all these manuals in your pager together, then type :tcd inside less(1) to get to the first place where "cd" is defined, then press just t repeatedly to move on to the other places in turn. Admittedly, that way, it's a bit hard to see which manual you are looking at at any specific time, but when you find an instance that pleases you, you can type ?^NAME inside less to see the start of the respective manual to see its name. After that, you can use the "t", "T", and "n" keys alternatingly to move around among instance and see in which manual they are in. So we just learned that at least nine different cd commands are documented in various places, rather than cd not being documented at all. Which is the one you want to use? Learn to use your documentation tools! =:c) Yours, Ingo
