You can copy a diskette (opened as /dev/rfd0) to a file named floppy created in the current directory with the flcopy command. The message: Change floppy, hit return when done appears as needed. The flcopy command then copies the floppy file to the diskette.
For example, to copy /dev/rfd1 to the floppy file in the current directory, type:
flcopy -f /dev/rfd1 -r
For example, to copy the first 100 tracks of the diskette, type:
flcopy -f /dev/rfd1 -t 100
See the flcopy command in the AIX 5L Version 5.1 Commands Reference for the exact syntax.
