How to view the number of system digits (32/64 bits) in linux

Linux system is a 32-bit or 64-bit command 1, getconfLONG_BIT or getconfWORD_BIT2, file/bin/ls3, lsb_release-a4, arch5, uname-a6, check whether the/lib64 directory exists. you can also determine whether the directory is... in linux, you can view the number of system digits (32/64 bits). In linux, the Command 1, getconf LONG_BIT, getconf WORD_BIT, and file/bin/ls 3 are 32-bit or 64-bit, lsb_release-a 4, arch 5, uname-a 6. check whether the/lib64 directory exists and whether it is a 64-bit system. The 64-bit system has two directories:/lib64 and/lib. the 32-bit system has only one directory. It can be used as a basis for judgment. The method described above is simple and practical compared with the tool software. Share with me, hope to help those who are interested, haha !!
