Shell Programming and Scripting

Remove the CR's with:

Code:

tr -d '\r' < file > temp
mv temp file

I did not get you...CR's?? Sorry I am new to Unix...

Dos/windows editors place a line feed and a carriage return character at the end of each line of a text file, but Unix uses only a line feed character.
The code is to get rid of the carriage return.

Regards

Got your point but I am not able to get where and how to use it in my code...

You don't have to use it in your code but on the UNIX command line. Alternatively, tell your editor to save the file in UNIX encoding (almost all Non-MS editors can do that)

Thanks alot for your help but sorry I am still confused and not getting it

The lines in text files (including any script language) are separated with a line terminator (called EOL [End Of Line] in C++ for example). But not every OS uses the same kind. DOS/Windows uses 2 characters '\r' (Control character "Carriage Return") and '\n' (Control character "Line Feed"). UNIX uses just the '\n' (Line Feed) character. MacOS uses '\r'.
Since you wrote and saved your script on Windows, the default setting of your editor probably placed the two characters '\r' and '\n' at the end of every line, instead of only '\n', which UNIX would expect. In order to get your file into a format that UNIX will understand properly you have two options:
Note: The two characters Carriage Return and Line Feed come from a time long long ago, when output was still done on needle printers instead of monitors. Carriage Return told the printer to move the printer head to it's leftmost position, Line Feed told it to advance the paper feed by one line
