Find RPM package software: rpm -qa ×××*

Note: ××× refers to the first few letters of the software name. It is not required to be written completely, but it is not wrong. * is the wildcard number "*", that is, asterisk. If you want to find the REALPLAYER software installed in the machine, you can enter: rpm -qa realplay*

3. After finding the software, the complete name of the software is displayed, such as firefox-1.0.1-1.3.2.

Execute uninstall command: rpm -e firefox-1.0.1-1.3.2

=== Installation directory, execute command to find: rpm -ql firefox-1.0.1-1.3.2

2. Use the CD command to enter the directory where the source code compression package is located.

3. Extract the file according to the compressed package type (* represents the compressed package name)

tar -zxvf ****.tar.gz

tar -jxvf ***.tar.bz(or bz2)

4. Use CD command to enter the decompressed directory

=== Installation directory: Note the installation directory during the make install command, or read the readme file inside the installation directory. Of course, the best way is to specify the installation directory during installation, that is, in./ configure command followed by parameters-prefix=/**，

For example: .../ configure-prefix=/usr/local/aaaa, i.e. install the software in the aaaa directory of the/usr/local/path. The default installation directory for general software is in/usr/local or/opt, which can be found there.

=== can be specified during installation, similar to windows installation.

2. How to execute after installing the software. After installing the software, there are several ways to execute it:

A. Some software will automatically add shortcut keys to the application list after installation, just like windows, go there to find it.

B. If you can't find it in the application list, you can enter the command directly in the/start/run command: the startup command is generally the software name, such as firefox, realplay, xmms, etc.

C. You can also open a shell terminal and enter the software name, just like in "Run Command". If you don't know the whole command, you can enter the first letter, and then press the tab key to find, the system will automatically display all commands starting with the input letter/

D. You can also run the startup file directly under the installation directory. The executable icon under Linux is very similar to the shell terminal icon.

E. Go to the/usr/bin directory to find the installed software startup file and execute the command. Linux systems put all executable file commands in the/usr/bin directory are made boot links, you can go to that directory to find your installation file boot command, double-click boot.
