Please use CODE tags when displaying sample input, sample output, and code segments.
In which editor did you originally write the code?
The script runs fine for me but when I write it in a text editor like OpenOffice and then paste it into vi then I get a problem similar to the one you describe.
And indeed, the command cat -A hello then shows all kind of characters that don't belong there.
I would like to point out a few other issues that seem to not be causing errors just yet:-
The opening line of #! /bin/bash should be #!/bin/bash without the space.
The line starting Echo would probably cause an error unless you have a script, alias or function called Echo where i suspect you really want echo, all lower case. This could suggest autocorrect in your editor. You are better coding in something plain like Notepad, Vi or Emacs
When testing the input file name, you should really quote the string. The user could type spaces, nothing at all or even the string duff -o : which might still say the file exists even if it doesn't. You should use if [ -e "${file_name}" ] to eliminate these issues
thanks for your replies, here are the feedback you asked for :
1- i am using Cygwin on my windows 7 machine.
2- i am using visual studio 2010
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$

3- i removed the space as suggested but it has no impact on the result, same error i am getting
thanks

Good morning,
I am 100% mew to Unix and am trying to troubleshoot why a pgm written 3 years ago, suddenly is not working properly. It is part Perl with some UNIX commands thrown in. I need to verify what the UNIX commands are doing before I can continue with my other troubleshooting.
