Hi there, I found recently when trying to save output from a script for later inspection that "tee" and file redirections seem to have massive delays when run in Cygwin - usually nothing is written to file or stdout until after the command has finished - not very helpful. I'm running a bash script with the following cmdlines: "bash ./path/to/script.sh > stdout.log" and: "bash ./path/to/script.sh | tee stdout.log" Both of them result in no writes to the file (or stdout in the second case) until the command is finished, and as this script takes minutes to run, it's not very helpful. I'm running these commands from bash in Mintty. Is there any configuration I need to do, or have I potentially discovered a bug? IIRC there have been some changes in the dev version of Cygwin relating to file I/O so perhaps this is already fixed? Hamish
