These variables are typically 41used by the system to resolve variant symlinks but may also be used generally. 42.Pp 43For each operand set, modify, retrieve, or delete the specified variable. 44By default variables specified without data are retrieved and variables 45specified with data are set. Variables may be set to empty. 46.Bl -tag -width Ar 47.It Fl a 48List all variables at the specified level. Note that per-process variables 49override per-user variables and per-user variables override system-wide 50variables. By default, per-user variables are listed. 51.It Fl q 52Quiet mode. When retrieving a variable only its data is printed. 53.It Fl d 54Delete mode. The specified variables are deleted. Any specified data is 55ignored. 56.It Fl s 57This option causes variables to be set system-wide and restricts retrievals 58to system-specific variables. 59.It Fl u 60This option causes variables to be set on a per-user-id basis and restricts 61retrievals to user-specific variables. This is the default. 62.It Fl p 63This option causes variables to be set on a per-process basis and restricts 64retrievals to process-specific variables. Note that since 65.Nm 66is run as its own process, using this option to set a variable will not 67affect your shell's namespace. 68.El 69.Sh RETURN VALUES 70The 71.Nm 72utility exits with one of the following values: 73.Bl -tag -width Ds 74.It 0 75No errors occured. 76.It 1 77A requested variable could not be found 78.It 2 79A requested variable could not be set 80.El 81.Sh SEE ALSO 82.Xr ln 1 , 83
