Windows XP home edition GNU bash, version 2.05b.0(9)-release (i686-pc-cygwin) cygwin dll version 1.3.22 cygcheck -s -v -r attached So I have observed a strange phenomenon, where if I execute "man bash" in (using bash) and then suspend with ^Z, maybe one time in 4 there is a situation where the first keypress after the suspend still somehow gets sent to less rather than to the shell. Subsequently the shell works fine but when I "fg man" it only wants to draw the display a line at a time (ie it never refreshes the screen, even with ^L). Strangely, this behaviour happens much more frequently for "man bash" from xterm and not from the console, and even more strangely it seems much more likely to happen with the bash man page instead of others, though I have occasionally seen it with, eg, "man man". If you're looking to reproduce it, for me the best way is "man bash" from an xterm then repeatedly ^Z and "fg" until this happens (usually after 4 or 5 tries). Looking through the cygwin mailing list archives it seems that there have been problems along these lines before. It was supposedly fixed in cygwin-1.3.13-1. There is a message from Christopher Faylor "Re: Ctrl-Z hang" http://sources.redhat.com/ml/cygwin/2001-01/msg00839.html where he says that it was due to ^Z sending SIGTSTP to less but then bash grabbing the tty back from less while less was still trying to read the tty. The fix was to not send a SIGTTIN in this case but I guess that maybe this fix is causing the behaviour I see now. This is what it looks like from an xterm (see below for console): OPTIONS In addition to the single-character shell options documented in the description of the set builtin command, bash interprets the following options when it is invoked: : [2]+ Stopped man bash Lev@raajsgdh ~ : Lev@raajsgdh ~ $ % man bash : -c string If the -c option is present, then commands are read from : string. If there are arguments after the string, they are : assigned to the positional parameters, starting with $0. : And this is what happens at the console: Lev@raajsgdh ~ $ fg man bash Lev@raajsgdh ~ $ fg man bash Error executing formatting or display command. System command (cd /usr/man && (echo ".pl 1100i"; /bin/cat '/usr/man/man1/bash.1 '; echo; echo ".pl \n(nlu+10") | /usr/bin/tbl | /usr/bin/nroff -c -mandoc | /usr /bin/less -isrR) exited with status 256. No manual entry for bash Lev
