找到-exec与多个命令 [英] find -exec with multiple commands

问题描述

我试图使用find -exec有没有任何成功多个命令。是否有人知道，如下面的命令是可能的吗？

I am trying to use find -exec with multiple commands without any success. Does anybody know if commands such as the following are possible?

find *.txt -exec echo "$(tail -1 '{}'),$(ls '{}')" \;

基本上，我想打印在当前目录和打印每个txt文件的最后一行在该行，逗号后的文件名末尾。

Basically, I am trying to print the last line of each txt file in the current directory and print at the end of the line, a comma followed by the filename.

推荐答案

找到也将接受多个 -exec 部分的命令：

find will also accept multiple -exec portions to the command:

find . -name "*.txt" -exec echo {} \; -exec grep banana {} \;

请注意，在这种情况下，第二个命令将只在第一个成功返回时，运行由@Caleb提及。如果你想，无论其成功或失败的两个命令来运行，你可以使用此结构：

Note that in this case the second command will only run if the first one returns successfully, as mentioned by @Caleb. If you want both commands to run regardless of their success or failure, you could use this construct:

find . -name "*.txt" \( -exec echo {} \; -o -exec true \; \) -exec grep banana {} \;
