Start origin tcl shell: tclsh (apt-get install tcl);
-
Start tcl shell with command history shortcuts (up arrow for previous command and other powerful command line shortcuts like alt+backspace, brackets matching, etc. on Ubuntu): rlwrap -c tclsh;
For efficiency, add alias tcl="rlwrap -c tclsh" to ~/.zshrc;
Note: rlwrap is readline wrapper;
