The example near the top of Sobell, page 486, demonstrates a way to put a variable in the environment of a script you are calling without declaring the variable in the interactive shell you are running. Use this technique to assign a value to myvar, place it in the environment of echomyvar, and run echo- myvar. After running the script, is myvar set in the interactive shell?
What will be an ideal response?
$ myvar=sam ./echomyvar
The PID of this process is 4411
The value of myvar is: sam
$ echo $myvar
$
No, myvar is not set in the interactive shell.
