The file can't be binary and text. I would guess the file is a binary file and has not been exported correctly.
You can try to use the command file which will attempt to identify what format the file uses.
if its a text file you should get back something like
Code:
myfile.csv: ASCII English text, with CRLF line terminators
The with CRLF line terminators indicates that its a text file saved in the format windows uses. Windows stores lines of text that end in a Carridge Return and then a Line Feed Charicter. Unix & linux uses a Line Feed charicter only.
