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

tcl(1) General Commands Manual tcl(1)
NAME
tcl, tk, tcl-tk - Tool Command Language
DESCRIPTION
The tcl software is unsupported software that is provided as part of Tru64 UNIX. Compaq will fix problems in this unsupported software
only if they are specific to Tru64 UNIX. Compaq will not fix problems that are integral to the software itself or that occur when the com-
ponent is used on UNIX systems other than Tru64 UNIX. Compaq will not add functionality to this software.
Except for this reference page, other reference pages that Tru64 UNIX supplies for tcl are passed through without changes. The reference
pages distributed as part of this software are available in the directories /usr/share/doclib/annex/man/man[1-9]. You should use this
directory stem in the man command or add it to the MANPATH environment variable to make these files available to the man command.
Note
Compaq is not responsible for the content or quality of reference pages and other documents installed under the /usr/share/doclib/annex
directory and does not revise this material in response to customer problem reports. Reference pages installed under the
/usr/share/doclib/annex/man directory are not available from Compaq in book form; for example, they are not included in the reference manu-
als that you receive when you order the Tru64 UNIX documentation set as hard copy books.
Problems related to the content or quality of any documentation installed in the /usr/share/doclib/annex directory tree should be sent to
the developers of the documentation.
The format for changing the search path with the man command is: man -P /usr/share/doclib/annex/man [section] title...
If you are using the Bourne, Korn, or POSIX shells, use the following command sequence to modify your environment: MANPATH=$MAN-
PATH:/usr/share/doclib/annex/man export MANPATH
If you are using the C shell, enter the command: setenv MANPATH `echo $MANPATH`:/usr/share/doclib/annex/man
See the reference pages for the man(1) command for additional information on the search path used to locate files.
The reference pages associated with this product are not included in the whatis data base created by the catman command. Therefore, the
man -k and apropos commands will not locate reference pages included with this product.
