NAME¶
envstore
—
save and restore environment variables
SYNOPSIS¶
envstore |
command
[ args ... ] |
DESCRIPTION¶
envstore
can save and restore environment
variables, thus transferring them between different shells.
command must be one of
clear
- Forget all stored variables
eval
- Produce shell code for evaluation, restoring all saved variables
list
- List saved variables in better readable format
save
variable
[value
]
- Save variable either with its current
shell value or with value
rm
variable
- Remove variable from store
Note: Only the first character of
command is
checked, so
envstore
e
instead of
envstore
eval
,
envstore
c
for
envstore
clear
, etc., are also valid.
ENVIRONMENT¶
ENVSTORE_FILE
- The file in which the environment parameters are stored,
/tmp/envstore-EUID
by default,
LIMITATIONS¶
Variable names or values must not contain null bytes or newlines.
Due to limitations imposed by most shells, it is not possible to save parameters
containing more than one consecutive whitespace.
envstore
will save and display them
correctly, but unless you do
IFS
trickery,
your shell will not be able to load them.
The current maximum length (in bytes) is 255 bytes for the variable name and
1023 bytes for its content.
