Re: Bash heredoc on FD 3

Using this file:

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?

Same for me and interestingly:

$ ls -ld /dev/fd/*
ls: cannot access '/dev/fd/3': No such file or directory
ls: cannot access '/dev/fd/31': No such file or directory
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec  3 10:39 /dev/fd/0 -> /dev/pty2
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec  3 10:39 /dev/fd/1 -> /dev/pty2
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec  3 10:39 /dev/fd/2 -> /dev/pty2
