I'm currently writing a small script to backup bulks of floppy disks and format them afterward for later use.
I use dd
to copy the disk's image and cp
to copy all the files on the disk.
Here are the commands I use to do so:
# Copying disk image
dd if="/dev/fd0" of="/path/to/backup/folder" &>/dev/null && sync
# Copying disk files
cp -R "/mnt/floppy/." "/path/to/backup/folder/" &>/dev/null
After this process, the script needs to format the floppy disk. My problem is that I want my script to format the floppy disk only if both backup commands (dd
and cp
) were successful.
For example, if dd
couldn't copy all 1.44MB of the floppy disk because of bad blocks, then do not format the floppy disk.
How can I test if both commands were successful (They must be tested seperatly, as I do not always backup both disk's image and files)?
