The offset number may include a "0x" prefix, and then the number will be +read as a hex value. It is possible to specify multiple -o options. +.IP "\fB\-p, \-\-parsable\fP" +Print out in parsable instead of printable format. Encode all potentially unsafe +characters of a string to the corresponding hex value prefixed by '\\x'. +.SH AUTHOR +Karel Zak <kzak@redhat.com>. +.SH AVAILABILITY +The wipefs command is part of the util-linux-ng package and is available from +ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/. +.SH SEE ALSO +.BR blkid (8) +.BR findfs (8) + |
