Question

我正在尝试从nodejs（在Linux中）执行以下命令

const exec = require('child_process').exec;
exec('cd "/tmp/export/lessons/4/content/RES-52298196-ce0f-4d91-8aa5-53f4f8e4ecb9/ui" && rm -r !("M345")', (err) => console.log(err));

但是我得到以下输出

Error: Command failed: cd "/tmp/export/lessons/4/content/RES-52298196-ce0f-4d91-8aa5-53f4f8e4ecb9/ui" && rm -r !("M345")
/bin/sh: -c: riga 0: errore di sintassi vicino al token non atteso "("

  code: 1,

  cmd: 'cd "/tmp/export/lessons/4/content/RES-52298196-ce0f-4d91-8aa5-53f4f8e4ecb9/ui" && rm -r !("M345")'
}

但是，如果我尝试直接从终端这样运行相同的shell命令

$ cd "/tmp/export/lessons/4/content/RES-52298196-ce0f-4d91-8aa5-53f4f8e4ecb9/ui" && rm -r !("M345")

它按预期工作正常。我在哪里做错了？

Answer 1

尝试像child_process.exec一样将shell选项传递给{ "shell": "/bin/bash" }

Answer 2

我通过使用find命令而不是rm来解决，就像这样：

var ui = "folder_i_want_to_save";
var myPath = "/path/to/base/directory";
var cmd = `find . -type d ! -name . ! -name '${ui}' -exec rm -rv {} +`;
exec(cmd, { cwd: myPath }, (err) => console.log(err));

我还删除了命令的cd部分，并将其作为cwd参数传递。不幸的是，这是一种解决方法，而不是对语法错误的真正解决方案。

在Node.js中执行Shell命令会产生意外错误
