.wipefs file1/10/2023 For more details see mount(8).ĭisplay version information and exit. The list or individual types can be prefixed with 'no' to specify the types on which no action should be taken. More than one type may be specified in a comma-separated list. Limit the set of printed or erased signatures. Suppress output messages after successful signature wipe. Encode all potentially unsafe characters of a string to the corresponding hex value prefixed by '\x'. Print out in parsable instead of printable format. "K" has the same meaning as "KiB"), or the suffixes KB (=1000), MB (=1000*1000), and so on for GB, TB, PB, EB, ZB and YB. The offset argument may be followed by the multiplicative suffixes KiB (=1024), MiB (=1024*1024), and so on for GiB, TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g. It is possible to specify multiple -o options. The offset number may include a "0x" prefix then the number will be interpreted as a hex value. Specify the location (in bytes) of the signature which should be erased from the device. This is required in order to erase the partition table on a block device.Ĭauses everything to be done except for the write() call. For more details see EXAMPLES section.įorce erasure, even if the filesystem is mounted. The set of erased signatures can be restricted with the -t list option.Ĭreate a signature backup to the file $HOME/wipefs-.bak. Note that by default wipefs does not erase nested partition tables on non-whole disk devices. When used with option -a, all magic strings that are visible for libblkid are erased. ![]() It is possible that after wipefs -o offset the same filesystem or partition table will still be visible by another magic string on another offset. The device is not scanned for additional magic strings for the same filesystem. The wipefs command lists only the first offset where a magic string has been detected. Note that some filesystems or some partition tables store more magic strings on the devices. The set of erased signatures can be restricted with the-t option.-b,-backup Create a signature backup to the file HOME / wipefs-< devname >-< offset >.OPTIONS-a,-all Erase all available signatures. Wipefs calls BLKRRPART ioctl when erase partition table to inform kernel about the change. Note that by default wipefs does not erase nested partition tables on non-whole disk devices. When used without options -a or -o, it lists all visible filesystems and the offsets of their basic signatures. Wipefs does not erase the filesystem itself nor any other data from the device. Util-linux: /usr/share/man/man8/wipefs.8.Wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid. Or if wipefs is already installed and you need the package name % apt-file search "$(which wipefs)" Other examples for apt-file % apt-file search -regex "/wipefs$" To use apt_file you have to install it sudo apt-get install apt_file ![]() We know, that we search the binary, usually located in /bin, /usr/bin or /sbin, therefore your package name is util-linux and you can install it, as said with sudo apt-get install util-linux Util-linux: /usr/share/man/man8/wipefs.8.gz When used without options -a or -o, it lists all visible filesystems and offsets of their signatures. ![]() Wipefs does not erase the whole filesystem or any other data from the device. ![]() Util-linux: /usr/share/bash-completion/completions/wipefs Wipefs allows to erase filesystem or raid signatures (magic strings) from the device to make the filesystem invisible for libblkid. Manpages-fr-extra: /usr/share/man/fr/man8/wipefs.8.gz Manpages-de: /usr/share/man/de/man8/wipefs.8.gz To create a backup of all the signatures on /dev/sda, for example, we would write: sudo wipefs -all -backup /dev/sda The files that would be created, in this case is /root/wipefs-sda-0x000001fe.bak. But in your case apt-file search wipefs is the better choice. HOME/wipefs-.bak Each signature is stored in its own file. Apt-cache is a good idea if you now the package name.
