Beware that not only IFS is preserved -- every variable is preserved. Variable assignments inside the new shell don't copy into the old one. It's just like running commands behind a pipe.

Hi!
I'm new in these forums and more or less new with Unix. So... here is the question:
does anyone know where is redirected the output of a command when you put >&- after it?
Does it means any standard file descriptor?
Thanks! (2 Replies)
hi,
I would like to ask or is it possible to dump a hex using dd from starting point to end point just like the "xxd -s 512 -l 512 <bin file>"

Hope someone can share their knowledge..

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)

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.
