Use on Guardian Objects
The chmod command does not work on files in the /G directory. Once a file has been created in
/G, you cannot change its permissions with the chmod command.
To avoid errors when using the chmod command from the root directory (/), use the -W NOG
flag to prevent an attempt to access files in /G.
Environment Variables
The following environment variables affect the execution of the chmod command:
UTILSGE Specifies that HP extensions to the root directory should be omitted when the ini-
tial directory is root and a recursive operation occurs in an OSS shell command.
Application programs that test this variable might also honor its settings.
The UTILSGE value can be any of the following:
NOE Omit the /E directory.
NOG Omit the /G directory.
NOG:NOE Omit both the /G and /E directories.
The effect of assigning a value to the UTILSGE environment variable is the
same as specifying the -W NOG or -W NOE flag in the command.
EXAMPLES
1. To add a type of permission to several files, enter:
chmod g+w chap1 chap2
This command adds write permission for group members to the files chap1 and chap2.
