使用多个命令查找 -exec [英] find -exec with multiple commands

问题描述

我正在尝试将 find -exec 与多个命令一起使用，但没有成功.有人知道是否可以执行以下命令吗?

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，我正在尝试打印当前目录中每个 txt 文件的最后一行，并在行尾打印，逗号后跟文件名.

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

find 接受命令的多个 -exec 部分.例如:

find accepts multiple -exec portions to the command. For example:

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

请注意，在这种情况下，第二个命令只有在第一个命令成功返回时才会运行，正如@Caleb 所提到的.如果您希望这两个命令无论成功还是失败都运行，您可以使用以下构造:

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 {} ;
