can I able to open a chm file in Red Hat Linux OS???if yes how???

Answer 1

Yes.

Use this utility:
( it may require other updates to your Linux as well)
http://xchm.sourceforge.net/

xCHM is a cross-platform GUI front-end to chmlib, with borrowed bits from Pabs' chmdeco project.
Originally written for UNIX systems (Linux, *BSD, Solaris), xCHM has been since ported to Mac OS X and Windows.

xCHM can show the content tree if one is available, print pages, change font face and size, remember bookmarks, display a searchable index, and search for words in the current page and the whole book.
