我正在尝试在 Git 中创建一个预提交挂钩，它将检查任何调试代码并提示用户修复它。我有一个我正在寻找的正则表达式（忽略它不会排除多行注释中出现的事实！）：
grep -IiRn --exclude-dir={node_modules,vendor,public,lib,contrib} --include=\*.{module,inc,install,php,js} -P '^\s*(?!\/\/)\s*(dpm\(|dsm\(|console.log\()' /path/to/code/
当我在控制台中正常运行它时，这工作正常，但是当我在可执行.sh脚本中尝试它时，它什么也不做。以下没有一项对我有用：
#!/bin/sh
grep ...
MYVAR =`grep ...` # Note the backticks!
echo $MYVAR
MYVAR =$(grep ...)
echo $MYVAR
MYVAR ="`grep ...`"
echo $MYVAR
我尝试用 Python 来做，os.system()但也没有用。它似乎只是没有标准输出。我可能缺少一些明显的东西，但我处于松散的状态。
任何帮助将非常感激！谢谢。
编辑：
这是确切的脚本，尽管由于无法实际执行第一部分，它处于最早的可能阶段。我已经隐藏了确切的文件夹名称，因为最好不要在 SO 上共享我公司的代码库；）
#!/bin/bash
echo "Test!"
ONE=`grep -IiRn --exclude-dir={node_modules,vendor,public,lib,contrib} --include=\*.{module,inc,install,php,js} -P '^\s*(?!\/\/)\s*(dpm\(|dsm\(|console.log\()' /company/projects/company/www/sites/all/modules/custom/`
TWO=$(grep -IiRn --exclude-dir={node_modules,vendor,public,lib,contrib} --include=\*.{coffee} -P '^\s*(?!\#)\s*(dpm\(|dsm\(|console.log)' /company/projects/company/www/sites/all/modules/custom/)
