Operation and MaintenanceLinux Operation and MaintenanceHow to check how many bits a linux system has
1. Execute the 'uname -a' command
The highlighted i686 (or sometimes i386) description The operating system is 32-bit, but if it displays x86_64, it means that the operating system is 64-bit.
2. Run the 'uname -m' command
The output shows x86_64, which means the system is 64-bit

3. Use the file command
file /lib/systemd/systemd
to indicate that this is a 64-bit operating system. If it is displayed as 32-bit, it means that the operating system is 32 bit
4. Use the arch command
This command is used to output the hardware name of the machine. For a 64-bit operating system, the output should be x86_64
5. Through system setting method
