I have to give this one to my co-worker who discovered that the permissions on /tmp were incorrect: [user@host01 ~]$ ls -ld /tmp drwxr-xr-x 7 root root 4096 Jul 28 18:44 /tmp And we know they should be set with 1777: [root@host01 ~]# ls -ld /tmp drwxrwxrwt 7 root root 4096 Jul 28 18:44 /tmp Found this out when I tried to run nroff.

The normal way to go is: submit a patch to the maintainers/makers of the software. If you don't know who they are, you can just submit it to your distribution bug tracker.

The GNU C library has a reference manual that includes documentation for all or most of the data structures in the standard library and extensions. This has a type index. Beware there's also a "GNU C Reference Manual", but it and the "GNU C Library Reference Manual" are two different things. You can also autogenerate documention sufficient for browsing ...

Why not simply create one manpage and make the others links? That's how most, if not all, such programs do it. For example: $ ls -l /usr/share/man/man1/[ef]*grep.1.gz lrwxrwxrwx 1 root root 9 Nov 27 2013 /usr/share/man/man1/egrep.1.gz -> grep.1.gz lrwxrwxrwx 1 root root 9 Nov 27 2013 /usr/share/man/man1/fgrep.1.gz -> grep.1.gz As you can see ...

man displays man pages using a pager - in your case, less. When you press h, you're seeing less's help. So, as for what "spanning files" means, it's referring to searching across multiple files simultaneously opened in less.

The classic standard for this is from POSIX, Utility Argument Syntax (thanks to @illuminÉ for the updated link). It describes the syntax to be used in man pages, for example utility_name[-a][-b][-c option_argument] [-d|-e][-f[option_argument]][operand...] Being classic, it recommends using single-character options, with -W recommended for use by ...
