This article mainly describes the linux system 755 permissions refers to what, with a certain reference value, the need for friends can refer to the next. I hope you all have a lot of success after reading this article. Let's take a look at it together.

Linux system permissions generally use 1-3 digits to represent the permissions of the file owner, 4-6 digits to represent the permissions of the same group of users, and 7-9 digits to represent the permissions of other users. Specific permissions are represented by numbers, read permissions equal to 4, represented by r; write permissions equal to 2, represented by w; execute permissions equal to 1, represented by x; through the combination of 4, 2, 1, the following permissions are obtained: 0 (no permissions);4 (read permissions);5 (4+1| Read + execute);6 (4+2)| Read + Write);7 (4+2+1)| Read + write + execute).

Take 755 for example:

1-3 bits 7 = 4+2+1, rwx, owner has read, write, execute permissions;

● 4-6 bits 5 = 4+1+0, r-x, users in the same group have read and execute permissions but no write permissions;

● 7-9 bits 5, same as above, also r-x, other users have read and execute permissions but no write permissions.
