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.
