Public bug reported:
Here documents from the command line with tabs are not handled
correctly. Here is a transcript showing the problem - there is a tab in
front of "This is indented" in the file:
dzu@zarniwoop:~$ cat tab-test
#!/bin/bash
cat <<STOP
This is unindented
This is indented
STOP
dzu@zarniwoop:~$ bash tab-test
This is unindented
This is indented
dzu@zarniwoop:~$ echo "Now using mouse to copy&paste here-document"
Now using mouse to copy&paste here-document
dzu@zarniwoop:~$ cat <<STOP
> This is unindented
> This is indented
> STOP
This is unindented
This is indented
dzu@zarniwoop:~$
Dash handles this correctly:
dzu@zarniwoop:~$ dash
$ dash tab-test
This is unindented
This is indented
$ echo "Now using mouse to copy&paste here-document"
Now using mouse to copy&paste here-document
$ cat <<STOP
This is unindented
This is indented
STOP
> > > This is unindented
This is indented
$
The prompts in the dash output are suspicious but redirecting the output
into a file yields correct output.
