i should not remove the ^M characters by putting dos2unix command.
Actaully i want to find whether ^M character is present in the file or not by NOT opening the file.
i want some command like grep, i.e i want to grep and find for ^M characters int he file by not opening that text file.
In DOS, all lines end with a CR/LF combination or \r\n.
In UNIX, all lines end with a single LF or \n.
The ^M that you are seeing is actually a CR or \r. If you want to test for carraige returns in a file, you want to look for \r. Try this on the file:
You'll see tabs, vertical tabs, carriage returns, linefeeds and whatnot using the slash notation. I find this to be the best method for determining what actual characters are in a file.
Or, if you just want to see the ^M notation, you can use cat, like so:
If you want to remove the ^M characters, you can use dos2unix as suggested above, or the correct tr syntax:
