Purpose: collect pointers to various Wiki pages that discuss differences, similarities between Tcl and Unix shell languages. Also collect pointers to tools which help in the interactions between the two. ---- Recently, someone on news:comp.lang.tcl asked for a reference comparing a language such as bash and tcl, to help a bash programmer to learn to program in Tcl. Is anyone aware of such a help/HOWTO/etc.? ---- See [Tcl Heritage] for some of the influences on Tcl from various sources, including a number of Unix shell languages.
