I'd like to report a strange bug in 64-bit bash. The following script: ---- cut --- #/bin/bash -e DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" echo Works: $DIR ---- cut --- Simply exits and produces no output (never reaches echo). The same script works perfectly on 32 bits. Versions are the same: --- cut --- $ bash --version GNU bash, version 4.4.12(3)-release (x86_64-unknown-cygwin) Copyright (C) 2016 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later This is free software; you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. --- cut --- (of course i686 version prints "i686-pc-cygwin" here) If i remove "-e" argument, it starts working. If i break down the sequence into two lines: --- cut --- #/bin/bash -e DIR="$( dirname "${BASH_SOURCE[0]}" )" DIR="$( cd "$DIR" && pwd )" echo Result: $DIR --- cut --- then it also works on both versions of Cygwin.
