Description
filepath
An absolute path to the file on the server.
mode
A three-digit value, in which each digit specifies the file access for individuals and groups:
  • The first digit represents the owner.
  • The second digit represents a group.
  • The third digit represents anyone. Each digit of this code sets permissions for the appropriate individual or group:
  • 4 specifies read permission.
  • 2 specifies write permission.
  • 1 specifies execute permission. You use the sums of these numbers to indicate combinations of the permissions:
  • 3 specifies write and execute permission.
  • 5 specifies read and execute permission.
  • 6 indicates read and write permission.
  • 7 indicates read, write, and execute permission. For example, 400 specifies that only the owner can read the file; 004 specifies that anyone can read the file.

Example

The following example sets the access mode of a file so that only the owner can read the file.
