Thanks, Lassi (and many thanks also to Ulrich Lauther and Earnie Boyd who suggested the same). The manpage for bash version 2.01.1 says: MAILCHECK Specifies how often (in seconds) bash checks for mail. The default is 60 seconds. When it is time to check for mail, the shell does so before displaying the primary prompt. If this variable is unset, the shell disables mail checking. I didn't think of this as I have neither the MAIL nor the MAILPATH variable set, but in fact the bash manpage says about MAILPATH: MAILPATH A colon-separated list of file names to be checked for mail. [...] Bash supplies a default value for this variable, but the location of the user mail files that it uses is system dependent (e.g., /usr/spool/mail/$USER). I don't know what the default mail path for the bash.exe shipped with B19 is (echo $MAILPATH or $MAIL doesn't print anything), but I took a hex editor to look into the binary and found an instance of the string "unknown" not far from occurances of MAIL and MAILPATH. I patched the string from "unknown" to "no-idea", and guess what, the system started to query my name server for "no-idea". Gotcha. So, in order to summarize, there are two possibilities to get rid of the "pregnant pauses" syndrome: - Use the shell command `unset MAILCHECK' to disable bash's mail checking feature, which was causing this in the first place. (Attention: setting MAILCHECK to zero or to the empty string or to some garbage will *not* do, the variable must really be unset or the default behaviour applies!) - Create mounts for each drive letter X: to /X. For me, `mount -b D: /D' was all I needed to make the delays go away (D: is the system partition of my NT installation). I have no idea why (2) works, too, but it does. I guess one can find the explanation in the bash source code which I don't have handy right now. Maybe there are even configuration options to bash that can be used to build an executable which defaults to do no mail checks, and this would probably be the more natural default for bash on Windows as opposed to UNIX where every machine traditionally has its own mail system (hint to Cygnus for the next release!).
