What number represents the Sticky Bit in permission settings?

The Sticky Bit is represented by the number 1 in Linux file permission settings. This particular permission setting is associated with directories and is used to control the behavior of files within those directories. When the Sticky Bit is set on a directory, it ensures that only the owner of a file within that directory can delete or rename that file, even if others have write permissions to the directory itself.

This is especially important in shared directories like /tmp, where multiple users have permissions to write files. By setting the Sticky Bit, it prevents users from inadvertently deleting or altering each other's files, thereby enhancing data security and integrity.

In summary, the Sticky Bit's representation as the number 1 is crucial for managing file permissions effectively, ensuring that only the file owner retains control over their files within a shared environment.
