32 .Nd get and set user and system-wide variables for variant symlinks
40 program manages user and system-wide variables. These variables are typically
41 used by the system to resolve variant symlinks but may also be used generally.
43 For each operand set, modify, retrieve, or delete the specified variable.
44 By default variables specified without data are retrieved and variables
45 specified with data are set. Variables may be set to empty.
48 List all variables at the specified level. Note that per-process variables
49 override per-user variables and per-user variables override system-wide
50 variables. By default, per-user variables are listed.
52 Quiet mode. When retrieving a variable only its data is printed.
54 Delete mode. The specified variables are deleted. Any specified data is
57 This option causes variables to be set system-wide and restricts retrievals
58 to system-specific variables.
60 This option causes variables to be set on a per-user-id basis and restricts
61 retrievals to user-specific variables. This is the default.
63 This option causes variables to be set on a per-process basis and restricts
64 retrievals to process-specific variables. Note that since
66 is run as its own process, using this option to set a variable will not
67 affect your shell's namespace.
72 utility exits with one of the following values:
77 A requested variable could not be found
79 A requested variable could not be set
