set(1F) FMLI Commands set(1F)NAME
set, unset - set and unset local or global environment variables
SYNOPSIS
set [-l variable [=value]] ...
set [-e variable [=value]] ...
set [-ffile variable [=value]]... ...
unset-l variable...
unset-f file variable...
DESCRIPTION
The set command sets variable in the environment, or adds vari‐
able=value to file. If variable is not equated it to a value, set
expects the value to be on stdin. The unset command removes variable.
Note that the FMLI predefined, read-only variables (such as ARG1), may
not be set or unset.
Note that at least one of the above options must be used for each vari‐
able being set or unset. If you set a variable with the -ffilename
option, you must thereafter include filename in references to that
variable. For example, ${(file)VARIABLE}.
FMLI inherits the UNIX environment when invoked.
OPTIONS-l Sets or unsets the specified variable in the local environ‐
ment. Variables set with -l will not be inherited by pro‐
cesses invoked from FMLI.
-e Sets the specified variable in the UNIX environment. Vari‐
ables set with -e will be inherited by any processes started
from FMLI. Note that these variables cannot be unset.
-ffile Sets or unsets the specified variable in the global environ‐
ment. The argument file is the name, or pathname, of a file
containing lines of the form variable=value. file will be
created if it does not already exist. Note that no space
intervenes between -f and file.
EXAMPLES
Example 1 Using the set Command
Storing a selection made in a menu:
name=Selection 2
action=`set -l SELECTION=2`close
NOTES
Variables set to be available to the UNIX environment (those set using
the -e option) can only be set for the current fmli process and the
processes it calls.
When using the -f option, unless file is unique to the process, other
users of FMLI on the same machine will be able to expand these vari‐
ables, depending on the read/write permissions on file.
A variable set in one frame may be referenced or unset in any other
frame. This includes local variables.
