more on Re: bash process substitution "<(list)" [spot the difference]

[B. K. Oxley (binkley)]

I am exploring how process substitution works on Cygwin.  I have scripts 
which run fine on Linux but not on Windows XP.

Why does one of these scripts produce an error and the other does not?

Script #1:

$ cat a
#!/bin/bash

function f()
{
    echo "$1"
    cat "$1"
}

f <(echo OK)

$ ./a
/proc/self/fd/63
OK

Script #2:

$ cat b
#!/bin/bash

function f()
{
    ls -l "$1"
    cat "$1"
}

f <(echo OK)

$ ./b
lrwxrwxrwx 1 luser None 0 May 29 15:49 /proc/self/fd/63 -> pipe:[1728]
cat: /proc/self/fd/63: No such file or directory

Thanks,
