tab in bash is indeed filename expansion. what are 'my here' docs ? not familiar with that phrase.
A *here document* is a special-purpose code block. It uses a form of I/O redirection to feed a command list to an interactive program or a command, such as ftp, cat, or the ex text editor.

I suspect that the shell is attempting to expand the '*' character. You need to escape the delimiter with a backslash to keep the shell from expanding:

I tried that earlier, and \EOF did not help. And I have env variables in the here doc I need replaced. If I had to SED the file as a second step, I would have. But like I said, \EOF did not make a difference.

Oh, this is done through cut-n-paste. Cut from my web howto into a terminal window (screen usbtty into the Centos server). Is Terminal suppressing the tabs from the clipboard? I am using Xfce.

I just did a test where I created a file, xit, with the here document in it and ran it with ./xit
This way, the tabs remained. So the 'problem' is when I am pasting the same lines (with tabs) into the terminal window. There bash is interpreting the tabs and not feeding them into the here doc processing.

yes, bash interprets stdin differently than not stdin.

ARGH!!!
So can I control this? I want the howto to be a cut-n-paste operation. And I want to support real tabs not a bunch of spaces as I had previously...

Try cat <<- EOF
Note the dash. And yes, you must use tabs. Spaces are suppressed whereas tabs are not.

It's certainly possible to include tabs in here documents, in shell scripts it works as expected.
However, when you input the here document on the command line in an interactive shell, the moment you enter the tab it immediately triggers Bash' programmable completion and the tab never reaches the here document.
To disable programmable completion (temporarily), run: bind 'set disable-completion on' To (re-)enable programmable completion, run: bind 'set disable-completion off'

This works just fine. Adds to all the sections where I have blocks with here documents with tabs, but better to turn it off and on each time, that assume it is in the right state.
Again, thanks.
