Convert a binary gmt file to an ascii file
gmt2dat gmtfile
gmt2dat reads a <legid>.gmt file and converts it to a regular ASCII text file that can be edited using the text editor. The ASCII text is sent to standard output and can be redirected to a file/program/printer, etc.
To convert c2104.gmt to ASCII:
gmt2dat c2104.gmt > c2104.ascii
dat2gmt(1), GMT(1)
