我想知道当结果从 diff 中产生时是否有办法在列的顶部打印文件名。目前我明白了；

diff -a --suppress-common-lines -y output_main.txt output_compare.txt
XXX Version X.X(X)                                    | YYY Version Y.Y(Y)
 ip address 10.10.88.50 255.255.255.254               |  ip address 10.10.89.50 255.255.255.254

有用的是：

 diff -a --suppress-common-lines -y output_main.txt output_compare.txt
    output_main.txt                                       output_compare.txt
========================                                  =======================
    XXX Version X.X(X)                                    | YYY Version Y.Y(Y)
     ip address 10.10.88.50 255.255.255.254               |  ip address 10.10.89.50 255.255.255.254
