How to set sticky bit?

To set the sticky bit on a directory in a Unix-like operating system, you can use the chmod command. Here are the steps to do so:

1. Open Terminal: Access your terminal or command line interface.

2. Use chmod Command: You can set the sticky bit using either symbolic or octal notation.

   • Using Symbolic Notation:

     chmod +t directory_name
     

     Replace directory_name with the name of the directory where you want to set the sticky bit.

   • Using Octal Notation: You can also set the sticky bit along with other permissions using octal notation. For example, to set the sticky bit along with read, write, and execute permissions for everyone:

     chmod 1777 directory_name
     

     Here, 1 represents the sticky bit, and 777 represents read, write, and execute permissions for the owner, group, and others.

3. Verify Sticky Bit: After setting the sticky bit, you can verify it by listing the directory's permissions:

   ls -ld directory_name
   

   Look for a t at the end of the permission string, indicating that the sticky bit is set.

Example

To set the sticky bit on a directory named shared_dir, you would run:

chmod +t shared_dir

or

chmod 1777 shared_dir

This will ensure that only the owners of files within shared_dir can delete or rename their files.
