What are the standard I/O streams?

You can use the attribute value _parent with the target attribute when you want a link to break out of:

A) the noframes element. B) a single frame. C) inline frames. D) nested frames.

Write the commands to remove all the space characters stored in the shell variable text. Be sure to assign the result back to text. First use tr to do it and then do the same thing with sed.

What will be an ideal response?
