是否有调用它的bash选项?

我发现在启动终端时使用的默认shell(使用Ctrl + Alt + T )是/bin/bash

并在bash上运行内置命令type

 type -p bash 

返回结果为:

 /bin/bash 

当我执行Ctrl + Alt + T或说bash时,建议运行相同的可执行文件。

这个shell与命令bash的调用相同,它的一些选项传递给它吧? 如果是,这些选项是什么?

作为一个例子,也许传递-i选项以使bash shell交互?

PS:也许这也是相关的,但我似乎无法拼凑所有碎片。

通常,不,终端没有通过任何选项进行bash 。 但是, bash会假设一组默认选项,具体取决于它的调用方式。 从man bash ,部分INVOCATION

 An interactive shell is one started without non-option arguments and without the -c option whose standard input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i option. PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to test this state. 

交互式shell进一步激活其他选项。 此外,一些默认值基于调用名称( sh vs bash )应用。 阅读( set部分):

 -h Remember the location of commands as they are looked up for execution. This is enabled by default. -m Monitor mode. Job control is enabled. This option is on by default for interactive shells on systems that support it (see JOB CONTROL above) -B The shell performs brace expansion (see Brace Expansion above). This is on by default. -H Enable ! style history substitution. This option is on by default when the shell is interactive. 

结合起来,只需在终端上调用bash就可以启用这些选项。

您可以通过检查$-特殊变量的值来确认:

 $ echo $- himBH 

可能设置的其他选项是您的终端设置为启动登录shell。 在这种情况下,终端显式传递-l作为选项。
