Environment: vax 11/750 running 4.1BSD vi version 3.6 csh version 4.1 10/9/80 (most modules) (see postscript for details). Problem: alias vi '(echo start; /usr/ucb/vi \!*; echo end)' vi file Now hit the break key. I get back to the shell with my terminal not reset. vi is still running. If I'm unlucky vi has (apparently) read keyboard EOF since it continuously scrolls my file by the screen until the end of file, at which point it prints its "At EOF" message ad infinitum. Vi must be killed manually. alias vi '/bin/csh -cf "echo start; /usr/ucb/vi \!*; echo end"' vi file works just fine, as does alias vi '(/usr/ucb/vi \!*)' vi file and alias vi /usr/ucb/vi vi file Note that just running vi in a subshell isn't sufficient; the subshell must contain multiple commands. Anyone know what's going on here? Seems that if this is a problem in the shell that it might bite someplace else too.
