Geometry Bash Mac OS

Mac is a very good OS, but I personally like Linux better. I have my Macs dual booted with Xubuntu, and I hardly go back to Mac. I guess it all depends what do you want to do.' The problem is I have some OS specific aliases so I was looking for a way to determine if the script is running on Mac OS X, Linux or Cygwin. What is the proper way to detect the operating system in a Bash script? Bash os-detection. Improve this question. Follow edited Mar 4 '18 at 17:32. If that doesn't suit you, our users have ranked more than 25 alternatives to PTC Mathcad and 14 are available for Mac so hopefully you can find a suitable replacement. Other interesting Mac alternatives to PTC Mathcad are Xcos (Free, Open Source), SymPy (Free, Open Source), Maple (Paid) and Mirai Math (Free, Open Source).

A Geometry Software is an important tool to use especially by students and teachers in the process of learning. With these, it is easy to work with the majority of the geometrical operations that for a long time have dependent on paperwork. Also, this software allows effectively and ease in sharing of the geometrical diagram and as a result greatly facilitate the learning process. In this review, we will be looking at some of the best software in this category.

What is Geometry Software?

A Geometry software is a computer application that is used for sketching and illustration of graphical data. This can be in a number of diagrams such as circles, cylinders, angle points and much more. Essentially, these software in this category are used professionally in the field of engineering and at the same time they are very popular when it comes to studying mathematics, especially at higher levels. With the use of this software, the process of coming up with the required illustrations is greatly reduced in terms of time as well as the ability to share.

Precompiled binary executables are available for DOS, Win32, Linux and Mac OS X from the download page.

DOS

DOS version of TestDisk can used under:

MS-DOS/FreeDOS
Windows 95
Windows 98

The hard disk must be detected by the computer's BIOS.

Note: In some rare cases, you may need to connect your hard drive directly to one of the motherboard's IDE connectors as some IDE 'add-on cards' are broken. They do not follow the same standard specifications used by TestDisk to find your drive.

Windows 95

You need to use the DOS version.Hard disks and other media that are larger than 32 Gigabytes (GB) in size are not supported under any version of Windows 95. support.microsoft.com/?id=246818

Windows 98

You need to use the DOS version.Windows 98 (with the correct patches) can handle hard disks larger than 32 GB - see: support.microsoft.com/?id=243450 for any info that might pertain to your version of Windows 98.

To handle hard disks larger than 137 GB, support for 48-bit Logical Block Addressing (LBA) must be available.

Windows

The Windows version of TestDisk refers to NT 4/2000/XP/2003 only; for Win 9x see DOS version of TestDisk.

Mac Os Bash Profile

Disk naming

Windows versions of TestDisk use /dev/sdX as the disk name (where 'X' would be a, b, c... etc. for your first, second, etc. drive location) rather than 'hdX' (the usual IDE designation). 'sdX' is the linux device name for SCSI hard disks, but TestDisk doesn't know if it's an IDE, SCSI or USB disk, because this name comes from the cygwin compiler used to make the Windows version of TestDisk. That compiler has internal mappings to Windows drives that use only the names sdX.

Mac Os X Bash Commands

Missing disk

If a digital camera or smart card isn't detected by TestDisk or PhotoRec, plug the memory card in a USB card reader.

Windows 2000 and 48-bit LBA

Windows 2000 SP3 added support for 48-bit Logical Block Addressing (LBA), which allows the OS to access hard disks larger than 137 GB. But, 48-bit LBA support must be 'enabled' in Windows 2000 SP3 or above! To do so, the EnableBigLba value must be defined and set properly in the Windows Registry by performing the following steps:

Start a Registry editor (e.g., regedit.exe). In Windows, click on Start -> Run, and enter regedit.
Navigate to the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapiParameters Registry subkey.
From the Edit menu, select New, DWORD Value.
Type the name EnableBigLba, then press ENTER.
Double-click on the new value, set it to 1, then click OK.
Close the Registry editor.
You must restart the machine for the change to take effect.

Windows XP and 48-bit LBA

Windows XP Service Pack 1 (SP1) adds support for 48-bit Logical Block Addressing (LBA), which allows you to access hard disks larger than 137 GB. support.microsoft.com/?id=303013

Linux

Linux and 48-bit LBA

Linux kernels since at least 2.4.19 have been able to access large disks (drives over 137 GB using 48-bit LBA); and some earlier kernels, such as Red Hat 7.3's 2.4.18-x, were patched. Check the specific features of your install to know for sure. Linux kernels 2.2.x and older are limited to only 65,535 cylinders.

Precompiled binaries

The following instructions will download the archive and run TestDisk or PhotoRec.

TestDisk and PhotoRec must be run as root:

Using sudo: sudo ./testdisk_static, sudo ./photorec_static
Using su: su -c ./testdisk_static, su -c ./photorec_static

Disk Geometry

You may have to use the Geometry menu to enter the correct disk geometry.

FreeBSD

Under FreeBSD 5.2-RC1 and possibly other versions, you may have to use the Geometry menu to enter the correct disk geometry.

Mac OS X (Intel)

New Mac including MacBook and Mac Pro have an Intel CPU and HardDisk is partitioned by default using EFI partition table. TestDisk & PhotoRec handle EFI since version 6.9, so you can use them to recover your data.

Mac OS X (PowerPC)

Starting TestDisk or PhotoRec

Open the Terminal program found in the /Applications/Utilities folder.
Using terminal commands such as cd (change directory), navigate to the folder where you downloaded or installed TestDisk.
- The only sure-fire way of doing this is typing cd(space) and then dragging the folder containing TestDisk into the Terminal window. This will copy the location of the TestDisk directory after the current command on the terminal command line.
- If you have the TestDisk folder on your desktop, the command would look something like: cd ~/Desktop/testdisk-6.4
Move into the folder inside the TestDisk folder, where the binary executables are stored (in darwin/ on OS X ports). The command for this would look something like: cd darwin.
Now it's time to run TestDisk (or PhotoRec). To do this, type sudo ./testdisk (or sudo ./photorec). The sudo command tells your system to run testdisk as root ('administrator', or superuser). You will be required to enter your password (no echo of the characters will be apparent on the screen), then press the enter key to validate .

Using TestDisk

Upon startup, the following will appear. Highlight the disk of interest and hit return/enter to select it.

Once the disk of interest is selected, you must tell TestDisk what type of partition table to expect. For OS X users, this is probably the [Mac ] option.

At this point, you should analyze the disk to see if TestDisk can determine the partion map to replace the possibly-corrupted version on the drive. Select [ Analyse ] from the menu and hit return/enter.

The following screen will appear, allowing you to tell TestDisk if the partitions are 'Primary' or 'Deleted' partitions. I'm not sure if it's critical to mark any as 'D' -- I believe they default to 'P'. Select proceed, and hit return/enter.

After analyzing, a screen will appear, informing you of the partitions that were found (the partitions will be colored green). Hit return/enter to return to the display of all the partitions found, which looks something like the screen below. You will need to copy/print this information for later, as it will be required for rewriting the partition table using pdisk. Copying to a text file is recommended, as partitioning your drive incorrectly could cause further problems. Once copied, select [ Quit ] and exit TestDisk.

Now you can use this information with pdisk to rewrite your drive partition map.

Repairing/Rewriting Your Drive's Partition Map

To rewrite the partition map given by TestDisk, use the command pdisk. If pdisk reports, 'No partition map exists,' it may be necessary to initialize the disk. Once the disk is initialized, the numeric entries defining the partition may be completed and a name may be assigned to the partition ('rec_part' in the example below). Given the following information from TestDisk,

Start pdisk: sudo pdisk /dev/rdisk1
In this example, the required pdisk commands are:
