Because the subshell is followed by a pipe , all the output of the subshell is sent to the next command in the pipeline .

因为subshell后面跟着管道，所以subshell的所有输出都通过管道传输给了下一个命令。

Here , the subshell command du-sh work | cut-f1 yields the total size of the work directory in a format compatible with pv .

在这里，子shell命令du-shworkcut-f1以与pv兼容的格式生成工作目录的总大小。

According to Hund 's rules , we present a concise formula with which atomic or ionic ground state can be difined only by the electronic number of not filled subshell .

根据Hund定则，给出了直接用未满壳层电子数确定原子、离子基态的数学公式。

The use of a subshell is preferable in cases when you are redefining environment variables in your list of commands and you do not want those definitions to apply to your current shell .

当您在命令列表中重新定义环境变量，并且您不希望将那些定义应用于当前Shell时，使用Subshell更可取。

在远程计算机上打开远程存档，将cat产生的字节流发送到subshell，这个subshell首先更改目录，然后对存档进行解压缩。

While it 's common to run a subshell to pipe aggregated output to a single command , you can also use a subshell to expand a command in place , just like back ticks .

尽管通常运行子Shell将聚合的输出通过管道传递给单个命令，但您还可以使用子Shell对命令进行扩展，就像反勾号那样。
