[/CODE]It's required so many \\\\\\\\\\\..., to reflect "\\"
That's because you're using double-quotes, where the shell handles escaping itself and needs two to tell it to ignore it. Try single single-quotes, where escaping doesn't happen in the shell:
And you can single-quote just part of an expression too, the way you've been doing with double quotes.
I just remembered another trick: IFS=$'\n' This will cause the shell to split only on newlines when expanding variables -- spaces in directory names won't bother it at all. IFS is a special variable telling it how to expand variables and how to split when using read. This is the 'clear text processing mechanism' you wanted

envstore
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.
