I thought this worked. Many web pages tell you it works. But bash is
ignoring tabs in my here docs. Worst, where there are two tabs, it is
functioning as a command expand in bash, where all files in the current
directory are listed to complete the command.
The following is the here doc I am using. Most likely the tabs will be
converted to spaces in this email. But the bottom line is, that while
processing all the double tables, all the files in the current directory
get listed, and the resultant file is all flush left, as if I had used
the +EOF option:
Thing is, I thought I tested this previously, so it is possible that
there is now something wrong in my environment causing the problem?
cat <<EOF>00-init.conf || exit 1

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: cat <<\EOF > 00-init.conf ... ...

If I had to SED the file as a second step, I would have. But like I said, \EOF did not make a difference. I just tried this on a Fedora system, and got the same problem, yet: http://stackoverflow.com/documentation/bash/655/here-documents-and-here-strings#t=201705051749422129426 Gives examples with tabs in it. As does: http://tldp.org/LDP/abs/html/here-docs.html 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?

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' Robbert On 05-05-17 20:16, Robert Moskowitz wrote:> I thought this worked.

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.
