Use rlwrap to add readline support to tclsh

rlwrap [1] is a GNU readline wrapper. it adds readline editing and command history to any command line app.To use it with tclsh, start tclsh with:

$ rlwrap tclsh

Useful options are -c (file name completion) and -f (add words from a file to the completion list).To use rlwrap with tclsh with file name completion type:

$ rlwrap -c tclsh

It would be nice to have a file of all words used in Tcl: commands and subcommands to set rlwrap up using the -f option.info commands and info procs could help with that. Maybe there are some *.syn files out there to provide such a database.
