Thanks but the script worked in the ksh etc

The script worked in true unix shells. I have a copy of my script untouched by DOS and it has the same problem. I understand the CR/LF problem maybe the true unix shells deal with CR/LF wheras bash does not. Is vim some sort of bastardized version of vi?

bash is interpetting the line breaks as a directory\r "\r" is appended to the to the destination file name. Why does it not "Ralph" on the echo staments?

I think it best to not use bash if real shells are available IMHO so I prefer not to force a real shell to use bash.

I guess my work around is to insert # before the CR. that would be compatible with any shell even bash.

I hate to bash bash since I downloaded it for free but I don't think it is as good as real unix shells.

The awk commands work as proven by command line execution using bash and previous scripts run in the korn shell.

In a KISS (Keep It Simple Stupid) script
Code:
 
touch Apple

results in
touch: cannot touch `Apple\r': No such file or directory

Code:
echo me thinks bash is not so good

result
me thinks bash is not so good(nonprinting characters)Smilie

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME
libbash -- A bash shared libraries package. DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may want to load and use in scripts of your own. It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries. Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded using ldbash(1) must answer 4 requirments: 1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash). 2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library exports. I.e. all the function that will be usable after loading that library will be listed in that line. 3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are required for our library. I.e. every bash library that is in use in our bash library must be listed there. 4. The library must be listed (For more information, see ldbashconfig(8)). Basic guidelines for writing library of your own: 1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions. 2. Try to declare all variables intended for internal use as local. 3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with: __<library_name>_ For example, internal function myfoosort of hashstash library should be named as __hashstash_myfoosort This helps to avoid conflicts in global name space when using libraries that come from different vendors. 4. See html manual for full version of this guide. AUTHORS
