是否有任何命令可以抑制冗余字符串？

使用此命令find $FOAM_TUTORIALS -type f -name fvSchemes|xargs grep -rh div\(phi,U\)|sort，我得到：

答案1

假设您的输入位于名为 的文件中inputfile.txt。

您可以运行： sed -e 's/ \+/ /g' inputfile.txt | grep -v "\/\/" | sort -u

解释：

  • sed -e 's/ \+/ /g' inputfile.txt将多个空白替换为一个空白。这样，执行最终排序/比较会更简单
  • grep -v "\/\/"删除注释行
  • 最终sort -u删除重复的行。

如果您不介意用一个空格替换多个空格，那么此解决方案效果很好。

这些命令可以通过这种方式合并到您的原始命令中：

find $FOAM_TUTORIALS -type f -name fvSchemes | xargs grep -rh div\(phi,U\) | sed -e 's/ \+/ /g' | grep -v "\/\/" | sort -u
