How do Linux newbies know where programs are installed?

For Linux novices, after finally installing a software, they find that they don’t know where it is installed, can’t find it, and even uninstall it is very difficult. Here is a summary of the path problems. :

It is sometimes very important to check the installation path (address) of a certain software in Linux. For example, if the quick start item of a certain file is deleted, or you want to create a quick start item, or want to delete or add installation files, etc., the command to check the file installation path is used in many places.

Here I will introduce to you the Linux command to view the file installation path (address).

1. Check the file installation path:

Since the software is installed in more than one place, let’s first check all the paths (addresses) of the file installation. Here we take hbase as an example.

For example, I installed Oracle, but I don’t know where the files are installed and in which folders. You can use the following command to view all file paths.

Enter in the terminal:

whereis hbase
Copy after login

Press Enter, if you have installed hbase, it will be displayed The address where the file is installed, such as mine (the installation address may be different).

hbase: /usr/bin/hbase /etc/hbase
Copy after login

If you have not installed hbase or the hbase installation has not been successful, the file path will not be displayed. Only prompt:

hbase:
Copy after login

2. Query the path of the running file:

If you only want to query the address of the running file of the file, just use the following command ( Still taking Oracle as an example):

which oracle
Copy after login

The result will show:

/usr/bin/oracle
Copy after login

3. Check the installation path of the software

Take mysql as an example:

1. You can directly enter the command:

service mysql status
Copy after login

If installed, it is enabled by default. If it is not installed, there will be a prompt.

If not installed, just enter the command:

apt-get install mysql-server
Copy after login

. (This is enough for ubuntu system.)

2,

mysql --version
Copy after login

3, View through rpm

Four, View Whether the software is installed

First we need to check whether the software has been installed, or check the name of the installed software package. For example, find out whether mysql is installed

rpm -qa |grep mysql
Copy after login

4. rpm -ql lists the files installed by the software package

rpm -ql xxx(安装包名称)
Copy after login

5. rpm -qal |grep mysql View the file storage location of all mysql installation packages

rpm -qal |grep mysql
Copy after login

6. Use yum search to find the corresponding software package that can be installed

yum search mysql
Copy after login

7. In addition to finding the file location based on the software package, the most commonly used method is to use find to find a keyword such as mysql. All file paths containing the mysql service

find / -name mysql
Copy after login

8. The Which command searches for the executable file path through the PATH environment variable, which is used to find the folder pointing to the command.

 which mysql
Copy after login

9. Whereis command It is similar to find, but the difference is that whereis searches faster through the locally structured database index. If the files or commands in the database are not updated, the information cannot be found

whereis mysql
Copy after login
