Unix and windows file formats are different. Sometime a Unix file which edit in Windows put a special character at the end of each line i.e ^M (CTRL+M). It can make that file useless sometime.

But no worry you can fix that with ease, just follow the procedure given below:

• Open the file in vim or vi

vi myfile

• Then press ESC key, and type

:%s/^M//g

• Remember ^M is a special character which can be generated as given in NOTE.

sed command can also be used for this as follows:

sed 's/^M//g' myfile> newfile

^M is also a special character here.

That’s all, your file is same as last.

NOTE: Hold the control key and then press v and m to get the ^M (CTRL+M) character.
