Multics guide from 1969 shows that Multics already had a primitive shell (in later editions called "command processor"), had a concept of user working directory, and two editors "edm" and "qed". The command "runcom" was used to run scripts, ASCII files that contain shell commands
In 1987, G. William May published a comparison of Multics I/O redirection with UNIX in "Multics Technical Bulletin". The results showed issues with the Multics design (and in the broader picture, why UNIX won)
@unix_byte My thread about the same book for anyone interested:
@unix_byte ".rc" files in UNIX are named after RUNCOM.
@unix_byte @brouhaha And the other Project MAC operating system had much the same in 1968. bitsavers.org/pdf/mit/ai/aim…
@unix_byte Multics also had ACLs, something UNIX didn't adopt (except for the B2 Secure version). #ProudMulticsUser
@unix_byte Were there religious battles between the "edm-ites" and the "qed-ites", if they were the vi and emacs of their day?
