- The list of authors has grown. It now includes Thompson, Ritchie, Ossana
- Morris, McIlroy, McMahon, Lorinda Cherry and Roberts.
- The manual was done with ~ed' and 'roff' (as was the first).
-
- 1) cc only has one option (-c)!!
-
- 2) the bugs section for dsw reads:
- 'The name "dsw" is a carryover from the ancient past. Its etymology
- is amusing but the name is nonetheless ill-advised.'
-
- 3) find(1) takes file names or inode numbers and prints pwds of all matches.
-
- 4) pr(l) takes only 3 options (l==78 lines, c==current date, m=-modify date)
-
- 5) ls(1) takes five (ltasd)
-
- 6) sort has no options!!
- 7) there is a cemt(2) system call to catch EMT traps.
- 8) there is a hog(2) system call (somewhat equivalent to nice(20))
-
- 9) catching interrupts is done by intr(2). The bugs reads
- 'It should be easier to resume after an interrupt but I don't
- know how to make it work.'
-
- 10) setting the modified date on a file is done by mdate(2)
- 11) sleep(2) sleeps for n/60 seconds. The bugs reads
- 'Due to the implementation the sleep interval is only accurate to
- 256/60 (4.26) seconds. Even then, the process is placed on a low
- priority queue and must be scheduled.'
-
- 12) qsort(3) uses its own comparison routine
-
- 13) the switch statement in C was supplied as a library function.
- (C was just starting)
