U.S. GEOLOGICAL SURVEY WATER-RESOURCES INVESTIGATIONS REPORT 93-4076 U.S. GEOLOGICAL SURVEY HYDRO-CLIMATIC DATA NETWORK (HCDN) STREAMFLOW CD-ROM [This is the \READ_ME.UNX file] The ASCII files on this CD-ROM were created on a PC. Because of this, each line of text in a file on the CD-ROM ends with the pair of characters carriage return and line feed (octal 015 012, decimal 13 10, or hexadecimal 0D 0A). On a UNIX machine, each line of text ends with just a line feed character. As a result, the extraneous carriage return is the last "character" of each line. It may be invisible or it may be displayed on the screen as ^M (control-M) depending on the method used to display the file. Copy ASCII files to hard disk from the CD-ROM with the tr command tr -d "\015" new_file_on_hard_disk to get rid of the unnecessary carriage return characters.
