Performance and modification of Mathematica in Ubuntu-feisy

In Ubuntu-feisy, Mathematica has been used for some time. Due to the superiority of the Linux system memory management mechanism (for details, I have to check the information, but it is said that; it is displayed when it is used to compute large programs.) The running speed does not need to be emphasized. However, I have been suffering from three small problems and am not used to them. 1. When running any program, the following prompt appears: [: 215: ==: unexpectedoperator [: 215: ==: unexpectedope

In Ubuntu-feisy, Mathematica has been used for some time. Due to the superiority of the Linux system memory management mechanism (for details, I have to check the information, but it is said that; it is displayed when it is used to compute large programs.) The running speed does not need to be emphasized.

However, I have been suffering from three small problems and am not used to them.

1. A prompt appears when running any program:

[: 215 :==: unexpected operator
[: 215 :==: unexpected operator

This solution is easy. Replace the Math script in the Mathematica executable file with the interpreter "#! /Bin/sh ""#! /Bin/bash ".

2. Numlock is blocked, not supported by keypad. You need to redefine the keyboard map and find the folder:

"$ MATH/SystemFiles/FrontEnd/SystemResources/X"

$ MATH is the installation directory of Mathematica. Open the XMathematica file, press ctrl + F to find a line with the word "secondaryModifierMask", and place the preceding annotator "!" Remove, such:

* SecondaryModifierMask: Mod3Mask
