Shell Programming and Scripting

Hi all,

i did typed the following code in vi and executed it.
#!/bin/sh
//notice the blank line here.
DATA=test
echo "$DATA"

There was no problem.

I then deleted the file using the rm command. I used ultraedit typed in the same file. , FTP it in and i got the following output
: command not found
test
I then edited the file using ultraedit, and removed the blank line, this time, i did not get the " command not found error".
i re tried on ultra edit, this time the following piece of code:
#!/bin/sh
//notice the blank line here.
//notice the 2nd blank line here.
DATA=test
echo "$DATA"

the output i got was
: command not found
: command not found
test

It seems the number of blank lines i entered using ultraedit will cause the corresponding number of :command not found message when i executed the script. However, this does not happen when i use vi. Any insights?

After you ftp the script, do a dos2unix on the script, and then run it.

The reason could be the extra \r characters at the end of each line.

Thanks for pointing out the cause, Vino.
