在cshell中：如何将一个变量设置为命令行输出？ [英] in cshell: How to I set a variable to the command line output?

问题描述

我想启动一个生成作业作为输出的批处理作业。
如何将jobid保存为环境变量并在cshell脚本中重新使用？
感谢和祝福，
Rollz

I do want to start a batch job that generates a jobid as output. How can I save the jobid as environmental variable and reuse it in the cshell script? Thanks and best wishes, Rollz

推荐答案

使用反引号将命令的输出替换为命令行。设置一个普通变量：

Use backticks to substitute the output of a command into the command line. To set an ordinary variable:

set varname = `start_batch_job`

设置环境变量：

setenv varname `start_batch_job`

你通常应该避免在C-shell中编写脚本，它有很多问题，脚本语言请参阅 Csh认为有害的。即使您使用它作为交互式shell，您仍然可以使用另一个shell，如bash或ksh作为脚本语言（当然，除了shell启动脚本）。

You should generally avoid scripting in C-shell, it has lots of problems that make it poor as a scripting language. See Csh Considered Harmful. Even if you use it as your interactive shell, you can still use another shell, such as bash or ksh, as a scripting language (except for your shell startup scripts, of course).
