chutils command

We can use the chutils command to set the file ownership and permissions for an entire installation to an owner or group that differs from the user that performed the initial installation.

For transitioning users: The chutils command delivered with WAS v8 and later has a behavior that is different from the behavior of the chutils command delivered with WAS Version 7 and earlier.trns

Considerations and limitations:

• The chutils command delivered with WAS v8 and later will not work for WAS v7 and earlier installations; and the chutils command delivered with WAS v7 and earlier will not work for WAS v8 and later installations.
• The chutils command is not available on Windows operating systems.
• The chutils command should be run by a root user.
• The chutils command can be run using multiple options at once.
• We cannot use the chutils command to modify permissions for directories that are parents of of WAS_HOME.

  If WAS_HOME is in User A's home directory and the root user uses chutils to change the ownership of WAS_HOME to User B, for example, WAS_HOME might still be inaccessible to User B because it is still a subdirectory of User A's home directory.

• We cannot use the chutils command to modify permissions for owner or world, although group permissions can be elevated to match owner permissions.

Location

The chutils command is located in the following directory:

WAS_HOME/instutils

The chutils command syntax is as follows:

chutils.sh
  -installlocation=installation_directory
  -setowner=user_name
  -setgroup=group_name
  -setmod=[reset | grp2owner | patchperm]
  -help
  -debug

This parameter is required unless you are currently in WAS_HOME.

-setgroup=group_name
