No man page either. And "getconf --help" is incomplete.
Try running getconf with np args.
$ getconf
Usage: getconf [-v specification] variable_name [pathname]
getconf -a [pathname]
Assuming that "-a" is "all",
$ getconf -a | wc -l
320
$ getconf -a
LINK_MAX 127
...
$ getconf LINK_MAX
Usage: getconf [-v specification] variable_name [pathname]
getconf -a [pathname]
So documentation is not only missing but necessary.
For sure. I do have getconf man pages on CentOS 7 and
Ubuntu 22.04. Very different pages!
I'd also like to see some docs on the meanings of the
variables. For example, is ARG_MAX the maximum NUMBER of
args or the maximum total length? I assume the former.
Probably need to read some source header files to be sure.
