DESCRIPTION
Thevarsym
program manages user and system-wide
variables. These variables are typically used by the system to resolve variant
symlinks but may also be used generally.
For each operand set, modify, retrieve, or delete the specified variable. By default variables specified without data are retrieved and variables specified with data are set. Variables may be set to empty.
-a
- List all variables at the specified level. Note that per-process variables override per-user variables and per-user variables override system-wide variables. By default, per-user variables are listed.
-d
- Delete mode. The specified variables are deleted. Any specified data is ignored.
-p
- This option causes variables to be set on a per-process basis and
restricts retrievals to process-specific variables. Note that since
varsym
is run as its own process, using this option to set a variable will not affect your shell's namespace. Instead you might want to use the-x
option to set local varsyms and exec a command. -q
- Quiet mode. When retrieving a variable only its data is printed.
-s
- This option causes variables to be set system-wide and restricts retrievals to system-specific variables.
-u
- This option causes variables to be set on a per-user-id basis and
restricts retrievals to user-specific variables. This is the default
unless
-x
is used. -x
- This option causes variables to be set only within the
varsym
process and its children, and also allows you to specify a command and arguments to exec after the var=data specifications.
EXIT STATUS
The varsym
utility exits with one of the
following values:
- 0
- No errors occurred.
- 1
- A requested variable could not be found
- 2
- A requested variable could not be set
