32 .Nd get and set user and system-wide variables for variant symlinks

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