Sigh....

Told you what was wrong with your script file. You mentioned that you wrote your script (see post #1) and then did:

So you have a file named "hello" which contains your script, no? Now, in this file there are erroneous end-of-line markers, because you posted this (#7)

Code:

$ cat -A hello
#!/bin/bash^M$
echo -e "enter the name of the file : \c"^M$
read file_name^M$
if [ -e $file_name ]^M$
then^M$
echo "$file_name found"^M$
else^M$
echo "$file_name not found"^M$
end^M$
^M$

It is now perhaps a 1-million-dollar, who-wants-to-be-a-millionaire, extremely hard to find out type of guess which file i meant to process when i told (#8) you to use:

Code:

sed 's/^M$//' /path/to/dosstyle.file > /path/to/unixstyle.file

(hint, because otherwise it would be unsolvable by mere humans: its the only one we talked about the whole time. Try three times and i'll tell you the answer.)

And,after this Nobel-prize-worthy puzzle, guess what i meant by the file name /path/to/dosstyle.file and, respectively, by the file name /path/to/unixstyle.file. Have you even tried to understand what i wrote about or did you just look at the command, didn't understand it immediately and said "didn't work"? What exactly "didn't work"? Or is that just an euphemism for "i couldn't be bothered to even try"?
