ENVSTORE(1)						    BSD General Commands Manual 					       ENVSTORE(1)

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. AUTHOR
