Comment on Linux command line techniques: IO redirection and piping

As far as redirection goes, this skipped the least known bit (IMHO), closing descriptors.

    jmhobbs@katya:~$ cat file-that-doesnt-exist
    cat: file-that-doesnt-exist: No such file or directory
    jmhobbs@katya:~$ cat file-that-doesnt-exist 2>&-
    jmhobbs@katya:~$
