Using this file:
$ cat hello.sh
awk -f /dev/fd/3 3<<eof
BEGIN {
print "hello world"
}
eof
it runs as expected with Dash:
$ dash hello.sh
hello world
However it fails with Bash:
$ bash hello.sh
awk: fatal: can't open source file `/dev/fd/3' for reading (No such file or
directory)
I tried also with Debian and both Dash and Bash work as expected. What is
causing Cygwin Bash to fail here?
