On my work machine, where there are at least 1600 machines on the network (a changing number, based on how many employees have their machines on), `ls - F //' takes an inordinate amount of time while stat'ing all of those machines (serves me right for having alias ls='ls --color=auto -F'). Also, I cannot get ctrl-C or `/bin/kill -s TERM' to interrupt the ls process while it is attempting to access each and every one of those machines; after more than 10 minutes of waiting I gave up and used `/bin/kill -s KILL' to get that shell back, with less than half the network traversed. $ cd // $ time \ls | wc -l 1723 real 0m0.133s user 0m0.060s sys 0m0.093s $ time ls ls: ABITLAB20: No such host or network path ls: ABITTST1: No such host or network path ls: ALICEB: No such host or network path ls: AT247: No such host or network path ls: AUTOPOINT: No such host or network path ls: BCASE: No such host or network path ls: BHORNE: No such host or network path ls: CC9032LT: No such host or network path ls: CCOOPER: No such host or network path ls: CDENNIS: No such host or network path ls: CHUCK: No such host or network path ls: CJOHNSON: No such host or network path ls: CLS: No such host or network path ls: CLWOOD: No such host or network path ls: CZACHER: No such host or network path ls: DALLEN: No such host or network path ls: DELTMODTEST: No such host or network path ls: DHART: No such host or network path ls: DIGENG6: No such host or network path ls: DLJACKSO: No such host or network path ls: DSTATES: No such host or network path ls: GALLEN: No such host or network path ls: GEE: No such host or network path ls: GRJONES: No such host or network path ls: GSTUDE: No such host or network path Killed real 11m57.623s user 0m0.186s sys 0m1.015s $ I don't know if there is a reasonable way to speed this up, because you want to ensure that //machine exists before allowing `cd //machine' to succeed, but don't want to go stat'ing every machine on the network when doing a readdir() on //. -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
