Mounting the /proc Directory

On some systems, you must mount the /proc directory if it is not currently mounted. If you use any of the following systems, determine if the /proc directory is mounted:

• Compaq UNIX
   
• SunOS 5.x
   
• IRIX

You can check if this directory is mounted by typing:

ls /proc

If it is mounted, the ls command prints a list of numbers. If you see an error message, or no message at all, the /proc directory is probably not mounted. Your system administrator can mount the /proc directory.
