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.
