如何将 find 命令返回的文件列表通过管道传输到 cat 以查看所有文件 [英] How to pipe list of files returned by find command to cat to view all the files
问题描述
我正在执行 find 然后获取文件列表.我如何将它传送到另一个实用程序，例如 cat(以便 cat 显示所有这些文件的内容)并且基本上需要从这些文件中grep 一些东西.
I am doing a find and then getting a list of files. How do I pipe it to another utility like cat (so that cat displays the contents of all those files) and basically need to grep something from these files.
推荐答案
管道到另一个进程(虽然这不会完成你所说的你想要做的):
Piping to another process (Although this WON'T accomplish what you said you are trying to do):
command1 | command2
这会将 command1 的输出作为 command2 的输入发送
This will send the output of command1 as the input of command2
-exec 在 find 上(这会做你想做的事情——但特定于 find)
-exec on a find (this will do what you are wanting to do -- but is specific to find)
find . -name '*.foo' -exec cat {} ;
(find 和 -exec 之间的所有内容都是您已经在使用的查找谓词.{} 将替换您找到的特定文件命令(在本例中为 cat {})；; 用于结束 -exec 命令.)
(Everything between find and -exec are the find predicates you were already using. {} will substitute the particular file you found into the command (cat {} in this case); the ; is to end the -exec command.)
将一个进程的输出作为命令行参数发送给另一个进程
send output of one process as command line arguments to another process
command2 `command1`
例如:
cat `find . -name '*.foo' -print`
(注意这些是反引号而不是常规引号(在我键盘上的波浪号 ~ 下).)这会将 command1 的输出作为命令行参数发送到 command2 中.请注意，包含空格(换行符等)的文件名将被分解为单独的参数.
(Note these are BACK-QUOTES not regular quotes (under the tilde ~ on my keyboard).)
This will send the output of command1 into command2 as command line arguments. Note that file names containing spaces (newlines, etc) will be broken into separate arguments, though.
