如何在不运行Bash脚本的情况下对其进行语法检查? [英] How do I syntax check a Bash script without running it?

问题描述

是否可以在不执行脚本的情况下检查bash脚本语法?

Is it possible to check a bash script syntax without executing it?

使用Perl，我可以运行perl -c 'script name'. bash脚本有等效的命令吗?

Using Perl, I can run perl -c 'script name'. Is there any equivalent command for bash scripts?

推荐答案

bash -n scriptname

也许是一个明显的警告:这可以验证语法，但不会检查您的bash脚本是否尝试执行不在路径中的命令，例如ech hello而不是echo hello.

Perhaps an obvious caveat: this validates syntax but won't check if your bash script tries to execute a command that isn't in your path, like ech hello instead of echo hello.
