VOTE FOR US ON RANKEDBYVOTES WHAT IS CHMOD? Chmod means ‘change mode’ and it changes file or directory mode bits (the way a file can be accessed). You can use chmod in the command line to change file or directory permissions on unix or unix-like systems such as linux or BSD. HOW TO USE CHMOD? You can change file permissions in this format: chmod [options] [mode] [file_name] You can change permissions using alphanumeric characters (a+rwx) or with octal numbers (777). Here’s a chmod example using for setting permissions so that: 1. Owner can read, write and execute 2. Group can read, write and execute 3. Others can read, write and execute Chmod example (alphanumeric): chmod a+rwx Chmod example (octal): chmod 777 WHAT ARE PERMISSIONS? Each file on a system has a set of permissions associated with it, meaning which users have access and what type of access they have. THERE ARE THREE TYPES OF USERS: 1. User, meaning the user who owns the file 2. Group, meaning the files defined ownership group 3. Other, meaning everyone else EACH OF THESE TYPES OF USERS CAN HAVE THREE TYPES OF FILE ACCESS: 1. Read (r), meaning the ability to look at the contents of a file 2. Write (w), meaning the ability to change the contents of a file 3. Execute (x), meaning the ability to run the contents of a file File access, meaning permissions, can be represented alphanumerically (using symbols like r for read, w for write and x for execute) or using octal numeric values (755 for example). CHMOD OPTIONS You can extend chmod permissions with options. Most popular options are: * -r for ‘recursive’, include same mode in subdirectories * -f for ‘force’, forge ahead with all objects even if errors occur * -v for ‘verbose’, show objects processed Tag Description -f, --silent, --quiet Suppress most error messages -v, --verbose Output a diagnostic for every file processed -c, --changes Like verbose but report only when a change is made --reference=RFile Use RFile's mode instead of MODE values -R, --recursive Change files and directories recursively --help Display help and exit --version Output version information and exit CHMOD SPECIAL MODES SETUID AND SETGID Setuid and setgid (short for 'set user ID upon execution' and 'set group ID upon execution', respectively) are Unix access rights flags that allow users to run an executable with the permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with temporarily elevated privileges in order to perform a specific task. While the assumed user id or group id privileges provided are not always elevated, at a minimum they are specific. SETUID FOR A DIRECTORY The setuid permission set on a directory is ignored on UNIX and Linux systems. SETGID FOR A DIRECTORY Setting the setgid permission on a directory ('chmod g+s') causes new files and subdirectories created within it to inherit its group ID, rather than the primary group ID of the user who created the file (the owner ID is never affected, only the group ID). Newly created subdirectories inherit the setgid bit. Thus, this enables a shared workspace for a group without the inconvenience of requiring group members to explicitly change their current group before creating new files or directories. Note that setting the setgid permission on a directory only affects the group ID of new files and subdirectories created after the setgid bit is set, and is not applied to existing entities.
