end of the line character
How do i determine what the end of the line character is in a text file. for eg. is it \n or \f or \t etc..

Is there a unix command for this?

I'd do something like
Code:
head -1 myfile | od -ta

For a DOS file, you get
Code:
0000000   m   y   l   i   n   e   cr  nl

(cr = \r, nl = \n)

For a UNIX file, you get
Code:
0000000   m   y   l   i   n   e   nl

Cheers

To quote from a manual page for a version of file included with recent Linux

Quote:
In addition, file will attempt to determine other characteristics of text-type files. If the lines of a file are terminated by CR, CRLF, or NEL, instead of the Unix-standard LF, this will be reported.
At the command prompt....

For a standard UNIX file (LF (i.e. \n) terminators)
$ file my_file
my_file: ASCII text

For a DOS file ( \r\n terminators )
$ file my_file
my_file: ASCII text, with CRLF line terminators

Cheers
