[Bug-ddrescue] possible bug on GNU ddrescue

[Prashant Subbarao]

Dear Mr. Antonio Diaz Diaz or To Whom It May Concern:

I really appreciate all the time and care that you put into creating this
very helpful utility. I used GNU ddrescue to recover most of the files onto
a new hard disk, /dev/sdc (below). Following the instructions on the man
page (
https://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Fill-mode),
I am attempting to use GNU ddrescue to fill the bad sectors in my recovered
hard disk with a random string, "RMEUHEJB", that I have put into a tmpfile.

address@hidden:~/Desktop$ printf "RMEUHEJB" > tmpfile

address@hidden:~/Desktop$ sudo ddrescue --fill-mode=l- tmpfile
/dev/sdc rescue.JustPlusMinus.log

*ddrescue: unrecognized option `--fill-mode=l-'*

*Try `ddrescue --help' for more information.*


I get the error above (emphasis added for clarity). I copied and pasted the
command straight from the man page, only changing the target device and
mapfile; so I don't think I made a mistake in the execution of the command.
Can you please advise me? I really appreciate your help and prompt
attention to this.

Best Regards,
Prashant Subbarao
