Man និង​ទទួល​យក​ជំនួយ

command --help and man command are the two most important tools at the command line.

Virtually all commands understand the -h (or --help) option, which will produce a short usage description of the command and its options, then exit back to the command prompt. Type:

man -h

or

man --help

to see this in action.

Every command, and nearly every application in Linux™, has a man (manual) file. It is as simple as typing man command to bring up a longer manual entry for the specified command. For example:

man mv

brings up the mv manual.

man man

brings up the manual entry for the man command, which is a good place to start.

man intro

is especially useful, displaying the introduction to user commands which is a well-written, brief introduction to the Linux™ command line.

There are also info pages, which generally go into more detail than man pages. Try:

info info

for the introduction to info pages.

If you aren't sure which command or application you need to use, you can search the man files.

To search the man files for konsole, try:

man -k konsole

Note

វា​ដូច​គ្នា​នឹង​ពាក្យ​បញ្ជា​ apropos ដែរ ។

To search only the titles of your system's man files, try:

man -f kde

Note

This is the same as the whatis command.
