dash does not read IFS properly

[Mike H]

Binary package hint: dash

When IFS is set in a script, and the script as started with dash, dash doesn't understand IFS properly.
IFS is set and the script name has a n or a t in it's name, dash removes those characters.
eg. script: /home/username/bin/testnew.sh
=========
#/bin/dash
IFS=' \t\n'
echo $0
=========

result:
/home/user ame/bi / es ew.sh

expected result:
/home/username/bin/testnew.sh

the same result happens if script is #!/bin/bash or #!/bin/sh and it is started with 'dash scriptname', since Ubuntu points /bin/sh -> /bin/dash this happens in almost every script.

Hi.
About the IFS "issue", i found an satisfactory explanation explanation for this here;
http://forum.soft32.com/linux2/Bug-409179-DASH-Settings-IFS-work-properly-ftopict70039.html
To sum it up, you should use

<CODE>
IFS='
'
</CODE>

instead, since the bash syntax isn't specified in POSIX.
As for how and under what conditions are run, look here;

So, to sum it up, i *think* this bug should be marked as "INVALID".

I need to clarify;
What i did above is to set IFS to "newline only". To set IFS to whitespace/tab/newline (e.g. reset it, you should use "unset IFS"). I was too quick to respond :)

Ok, closing as invalid, for the above reason.
