csh - C Shell, mainly shell scripting
awk/sed - more of pattern matching, regular expressions, string manipulation and substitution types of commands
tcl/tk - Tool Command Language/Tool Kit
PERL - Practical Extraction Language
tcl/tk and Perl are more or less both programming languages
used for scripting, application programming. Perl/Cgi has been
used for web scripting as a companion to HTML. perl can also
interface with databases such as Oracle, Sybase, mySQL, etc.
I have not used tcl/tk, but I believe it is like Perl and in addition
you can do some GUI (Graphical User Interface) development
with it.
C/C++ are programming languages, as we talked before.
Hopefully this help.
I would suggest that you search on yahoo, lycos, etc. to find more relevant information for what you are looking for or try to
buy some Unix (Applications) books, etc.
Best Wishes
