You can store a string like that in the shell. Putting it outside quotes has stripped all newlines and whitespace, however, try echo "$string"
Using it may mean you need to alter the value of IFS.
Your code...probably needs to be replaced. It's full of useless uses of cat and does so many external calls to perl, cut, sed, tr, that it's extremely redundant and monstrously inefficient. And so overcomplicated that I can't even tell what you're trying to do, at this point.
Dear all,
How can i unset arrays. I mean all the subscripts including the array after using them.
Could you direct me to some links of array memory handling in the korn shell.

So what I want to do is display the... (3 Replies)

We have 2 servers (L1000 and rp7410) running 11.11. We would like to hook them up to either a Hitatchi AMS 2500 or Hitachi USPV via fiber channel. I need to what drivers I need for this and if it will work. Oh, they are using HP Tachyon XL2 Fiber Channel Mass Storage Adapters.

I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 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.
