| # The chmod utility modifies the file mode bits of the listed files as specified by the mode operand. | |
| # It may also be used to modify the Access Control Lists (ACLs) associated with the listed files. | |
| =========================================================================================================================== | |
| # MODES # Modes may be absolute or symbolic | |
| =========================================================================================================================== | |
| # An absolute mode is an octal number constructed from the sum of one or more of the following values | |
| =========================================================================================================================== | |
| 4000 (the setuid bit). Executable files with this bit set will run with effective uid set to the uid of the file owner. | |
| Directories with this bit set will force all files and sub-directories created in them to be owned by the directory | |
| owner and not by the uid of the creating process, if the underlying file system supports this feature: see chmod(2) and | |
| the suiddir option to mount(8). | |
| 2000 (the setgid bit). Executable files with this bit set will run with effective gid set to the gid of the file owner. | |
| 1000 (the sticky bit). See chmod(2) and sticky(7). | |
| 0400 Allow read by owner. | |
| 0200 Allow write by owner. | |
| 0100 For files, allow execution by owner. For directories, allow the owner to search in the directory. | |
| 0040 Allow read by group members. | |
| 0020 Allow write by group members. | |
| 0010 For files, allow execution by group members. For directories, allow group members to search in the directory. | |
| 0004 Allow read by others. | |
| 0002 Allow write by others. | |
| 0001 For files, allow execution by others. For directories allow others to search in the directory. | |
| =========================================================================================================================== | |
| # SAMPLE VALID MODES | |
| =========================================================================================================================== | |
| 644 make a file readable by anyone and writable by the owner only. | |
| go-w deny write permission to group and others. | |
| =rw,+X set the read and write permissions to the usual defaults, but retain any execute permissions that are currently set. | |
| +X make a directory or file searchable/executable by everyone if it is already searchable/executable by anyone. | |
| 755 | |
| u=rwx,go=rx | |
| u=rwx,go=u-w make a file readable/executable by everyone and writable by the owner only. | |
| go= clear all mode bits for group and others. | |
