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

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
