Shell 程序,通常叫做命令文件,它由列在档案内的命令所构成。此程序在编辑器中编辑(虽然也可以直接在命令列下写作程序, online scripting),由 UNIX 命令和基本的程序结构,例如变量的指定、测试条件、和循环所构成。您不需要编译 shell 命令檔。Shell 本身会解译命令档中的每一行,就如同由键盘输入一样。shell 负责解...

shell 其实就是一个实用工具,准确的说,shell 是一个作为用户与 Linux 系统间接口的程序,它允许用户向操作系统输入需要执行的命令。 1.1 命令解释器 shell shell 是一个命令解释器,可以将用户输入的命令翻译成内核可以识别的代码,然后由内核去控制硬件;而内核则可以通过 shell 将硬件信息翻译成用户可识别的代码,展现...
1)Compare UNIX Shell Scripting with others 2)Can you tell me something about the Zombie Processes in shell scripting? These are generally defined as the scripts that have completed their life span but are yet to be picked by parent processes associated with them. In the process table, the us...
But Bash scripts are great because you don’t need anything else than Bash to run them. No compiler, no interpreter, just your shell. There are many things that you’ll miss from programming languages like Perl or JavaScript or Python. ...
