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：

    假设您的输入位于名为inputfile.txt.

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

    解释：

    • sed -e 's/ \+/ /g' inputfile.txt将多次出现的空白替换为一个空白。通过这种方式，执行最终的排序/比较更简单
    • grep -v "\/\/"删除注释行
    • 最终sort -u删除重复的行。

    如果您不关心用一个空格替换多个空格，则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
