Developed, in combination with bash)/BIN/TCSH (Consolidated C Shell, provides more features)/BIN/CSH (has been replaced by/BIN/TCSH)/bin/zsh (based on Ksh developed, more powerful shell) now the general shell is used by bash > with Command Auto-complement and other functions,

In the *unix system, the commonly used shell has sh,bash,csh/tcsh, ksh. SH comes from SystemV Unix, is the traditional Unix shell, until now many system administrators still like to use SH.Bash comes from BSD Unix, the syntax is very similar to C, so developers who typically have a C + + programming background are most likely to use it.Ksh is an extension of SH and absorbs some useful features of CSH, but

Currently, the popular Shell types include bash, ksh, and csh-general Linux technology-Linux technology and application information. For more information, see the following. Bash is the default Shell used in Linux. It is jointly completed by Brian Fox and Chet Ramey. It is short for Bourne Again Shell and has a total of 40 internal commands. Linux uses it as the default Shell because it has the following features: (1) You can use a function similar

FreeBSD in order to determine whether a process exists, the implementation of the Chsh-s/bin/bash command, unfortunately, is just disconnected, and then again link can not be able to su root in the administrative authority.

Starting with Android3.0 (API level 11), the Android 2D rendering pipeline provides better support for hardware acceleration. all of the drawing operations performed by hardware acceleration are done using the GPU on the View object's canvas . Because enabling hardware acceleration increases the need for resources, such an application consumes more memory.Hardwar

The Android standard hardware driver is divided into two parts, one is the hardware driver running in the Linux kernel, and the other part is the hardware abstraction layer running in user space. Using this method, the system can be hardware-independent, but also protect the interests of some manufacturers. In Android
