Linux provides a rich help manual that you do not have to look for when you need to see the parameters of a command, as long as you have a man.
The Linux Man Handbook has several chapters:
1, standard commands (command)
2. System calls (Systems Call)
3. Libraryfunctions (library function)
4, specialdevices (equipment description)
5. File formats (document format)
6. Games Andtoys (game and Entertainment)
7. Miscellaneous (Miscellaneous)
8, administrativecommands (Administrator command)
the manual for Man in Ubuntu is not installed by default. Here are just a few commands:
sudoapt-get Install manpages
sudo apt-get install manpages-de
sudo apt-get install Manpages-de-dev
sudo apt-get install Manpages-dev
or download from here: http://www.kernel.org/pub/linux/docs/man-pages/
unzip after download, enter the extracted folder from the terminal, enter the command:
sudo make install
This command installs the man under the/user/man directory, so the man has been successfully installed. Assuming the folder path after decompression is:/home/man, if you do not want to install, you can use:
Man–m/home/man + commands queried
in order to display the Chinese manual, download the Manpages-zh package.
before installing, run the locale command to see what your locale is, primarily affecting the values of the Lc_all,lc_ctype and LANG variables. If the locale is ZH_CN. UTF-8, you can run make U8 && makeinstall-u8, and if the locale is GB2312,GBK or GB18030, you can run make GB && MAKEINSTALL-GB; You can download the corresponding RPM package to install it, just as easily. For ZH_CN. UTF-8, should be installed man-pages-zh_cn-1.x, for gb2312,gbk,gb18030, should install man-pages-zh_cn-gb-1.x. See the discussion version for a description of the system with its default Chinese encoding for different distributions.
Note that when you have the same command, the man will probably not want the results, you can first use MAN-F query, and then use the Men + number + command name query.
