v21 v22 1002 1002 [=#footnote5 [5]] The rather awkward {{{`expr 484335 + 100`}}} (note the back quotes) can be replaced with `$((484335+100))` if `bash` or any [http://pubs.opengroup.org/onlinepubs/007908799/xcu/chap2.html#tag_001_006_004 POSIX 1997+] compatible shell is being used. Similarly the last argument can become `$((484335-100))`. See also ^[#footnote11 11.]^ below. 1003 1003 1004 [=#footnote6 [6]] `testdisk` scans the media for the beginning of file systems that it recognizes. It can be tricked by data that looks like the beginning of a file system or an old file system from a previous partitioning of the media (disk). So care should be taken. Note that file systems should not overlap apart from the fact that extended partitions lie wholly within a extended partition table allocation. Also if the root partition of a Linux/Unix installation can be found then the `/etc/fstab` file is a useful resource for finding the partition numbers of other partitions.1004 [=#footnote6 [6]] `testdisk` scans the media for the beginning of file systems that it recognizes.
