看看 gnu diff 实用程序结合进程替换:

$ diff -y <(ls ./tmp) <(ls ./tmp2)
20161201.csv                              <
20161202.csv                              <
aa.txt                              aa.txt
a.txt                               a.txt
bb.txt                              bb.txt
bsd.bsd                             bsd.bsd
b.txt                               b.txt

$ diff -y --suppress-common-lines <(ls ./tmp) <(ls ./tmp2)
20161201.csv                              <
20161202.csv                              <
