英汉例句

• the command in parentheses is a subshell: commands in the subshell don「t affect the environment of the current shell.

  括号中的命令为一个subshell：subshell 中的命令不会影响当前shell的环境。

• because the subshell has so many uses, you might prefer to use it always instead of a combination or the back tick operators.

  因为子shell有许多用途，所以与组合或者反勾号操作符相比，您可能更喜欢使用它。

• you can generally do this by running a list of commands in a subshell or by running a list of commands in the current shell.

  您一般可以通过在某个subshell 中运行一个命令列表或通过在当前shell 中运行一个命令列表来实现此目的。

• changes made in the subshell -- for example, changing directory -- do not affect your command line, but it does affect the environment of the subshell.

  subshell 中进行的更改，例如更改目录，不会影响到您的命令行，但是它将影响subshell的执行环境。

• whether to use a combination or a subshell depends on your intentions—although the subshell is much more powerful, as described next.

  是使用组合还是子 shell，这取决于您的目的，尽管子shell 的功能更强大一些，下面将对其进行描述。

• in listing 9, for example, if the first rsync failed, then the subshell would just continue and run the next command.

  例如，在清单9 中，如果第一个rsync失败，则子外壳将继续运行下一个命令。

• better yet, a subshell can contain another subshell, so expansions can be nested, too.

  然而更有价值的是，子 shell可以包含另一个子shell，所以还可以进行嵌套扩展。

• 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。

• the series of commands collected in parentheses runs in a subshell and does not affect the state of the current shell.

  在圆括号中的系列命令将在一个子shell 中运行，并且不会对当前shell的状态产生影响。

• run a list of commands in a subshell

  在subshell 中运行命令列表

• nevertheless, some drift is likely to occur because it does take a finite amount of time to launch each subshell for the background processing.

  但是，这个过程会发生一些时间偏差，因为需要花费一些时间启动每个子 shell 脚本来进行后台处理。

• the remote archive is opened on the remote machine, and the byte stream from cat is sent to a subshell that first changes directory, and then it extracts the archive.

  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。

• 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-shwork |cut-f1以与pv兼容的格式生成工作目录的总大小。

• 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。

• 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。
