How do I access man pages?
You can find man pages on the web. Just type man and the name of a command into your favorite search engine, and you’ll get plenty of hits. Apple has a documentation repository with man pages here. You can click Alphabetic Index to get a list of all commands, then search for the one you want.
Is man the same as apropos?
The differences between apropos and whatis are simply where in the line they look, and what they are looking for. Apropos (which is equivalent to man -k) searches the argument string anywhere on the line, whereas whatis (equivalent to man -f) tries to match a complete command name only on the part before the dash.
What does the apropos command do?
In computing, apropos is a command to search the man page files in Unix and Unix-like operating systems. Apropos takes its name from the French “à propos” (Latin “ad prōpositum”) which means about. It is particularly useful when searching for commands without knowing their exact names.
How do I print a man page?
Let’s say you have a printer that you have identified with the name hp_laserjet connected to your system. You want to print a man page about the ls command directly to that printer, so use the -t option (or –troff) and then pipe the output to the lpr command, identifying your printer with the -P option.
What command is same as the command apropos?
The apropos command is equivalent to using the man command with the -k option. Note: When the /usr/share/man/whatis database is built from the HTML library using the catman -w command, section 3 is equivalent to section 2 or 3. See the man command for further explanation of sections.
How does man search in whatis or apropos mode?
When operating in “whatis” or in “apropos” mode ( man -f and man -k, respectively), man actually invokes the whatis binary and delegates the search to it. On the other hand, when operating in its default mode (e.g. man page) or in “where” mode ( man -w page ), the search is performed by the man binary itself.
Why are there no man pages in Linux?
It’s quite possible there is no man page corresponding to what you’re looking for – either because the tool or functionality you’re searching for isn’t installed on the system or because it has no man page installed (the latter is far more common under Linux than elsewhere).
Are there directories for man pages in SunOS?
SunOS has no such option. Before trying this, make sure your MANPATH variable is set correctly. There can be several hierarchies of man pages, depending on the system. On most of our systems, at least the following directories exist: /usr/man, /usr/local/man.
How are missing parent directories created in man pages?
Standard entries,`.’,for the directory itself, and `..’ for its parent, are made automat- ically. The -p flag allows missing parent directories to be created as needed. With the exception of the set-gid bit, the current umask (2V) setting determines the mode in which directories are created.
