Today I was running a Shell Script on linux server that I uploaded from windows OS to Solaris machine.When I initiated that script I get ": bad interpreter: No such file or directory" error on the command line.
Some History behind this issue will make you understand this clearlly :-
Text files are often incompatible across operating systems. Why? Because each operating systems use different markers to indicate the end of a line. This will really create a big mess you up if you are trying to transfer files from one operating system to another.
The carriage return is often referred to by the capital letters CR. On a Macintosh, every line has a CR (^M – 13) at the end.
Under Linux (a variant of Unix), the end of a line is indicated by a line feed. Every line ends with a line feed or LF (^J – 10).
These are 2 characters with 2 very separate numeric representations on a computer. A CR is a 13 in the ASCII table of characters and an LF is a 10 in the ASCII table of characters.
Contributing to the confusion is that fact that Microsoft Windows does things yet another way. Under Microsoft Windows, lines end with a combination of 2 characters — a CR followed by a LF. Symbolically, this is represented as CRLF or carriage return, line feed.
Solution:
I am having ultraedit editor. In this editor when ever you open any file in the status bar it shouws you its type (DOS/MAC/UNIX)
if you want to convert a file from DOS to UNIX
File > Conversions > DOS to UNIX
And if you want to make each file bydefault to DOS/MAC/UNIX Advanced > Configuration > General Tab inside Editing go to "Default file types for new file" and select desired default type.
You can also refer Ultraedit FAQs http://www.ultraedit.com/support/faq.html
OR
Just create a new file inside UNIX and copy paste your DOS type content. When you save it, it will be converted to UNIX.
