Dobře udělaný software má ke každému programu manuálovou stránku. Mezi instalovanými se dá hledat příkazem apropos, který jako argument bere regulární výraz. Takže:

$ apropos . | head
$HOME/.odbc.ini [odbc] (5)  - unixODBC data sources configuration
*l [dialog]          (3)  - widgets and utilities for the *p program
*n [xterm]           (1)  - terminal emulator for X
*p [dialog]          (1)  - display dialog boxes from shell scripts
. [builtins]         (1)  - bash built-in commands, see bash(1)
.P Disclaimer: The functionality of this program is now available in the ntpd program. See the -q command line option in the ntpd [ntpdate] (8)  - Network Time Protocol (NTP) daemon page. After a suitable period of mourning, the ntpdate program is to be retired from this distribution
.P Disclaimer: This program has known bugs and deficiencies and nobody has volunteered to fix them in a long time. The good news is the functionality originally intended for this program is available in the ntpd and sntp programs. See the Deprecating ntpdate topic in the NTP Support wiki for a thorough discussion and analysis of the issues. See the -q command line option in the ntpd [ntpdate] (8)  - Network Time Protocol (NTP) daemon page and/or the sntp - Simple Network Time Protocol (SNTP) Client page. After a suitable period of mourning, the ntpdate program will be retired from this distribution
.ad l posix_trace_attr_getinherited [posix_trace_attr_getinherited] (3p)  - retrieve and set the behavior of a trace stream (TRACING) .ad b
.ad l posix_trace_attr_getlogsize [posix_trace_attr_getlogsize] (3p)  - retrieve and set trace stream size attributes (TRACING) .ad b
.ad l posix_trace_eventset_add [posix_trace_eventset_add] (3p)  - manipulate trace event type sets (TRACING) .ad b

Vypíše všechny. Ale jak vidíte, je trochu tupý, protože bere hned první řádek, co není v manuálové stránce komentář. Problém totiž je, že manuálové stránky jsou v podstatě volný text a tak se špatně strojově zpracovávají.

Existují i webové archivy manuálových stránek, například https://linux.die.net/man/ nebo https://www.mankier.com/. Ale z principu nemohou obsahovat všechno.
