有几种方法可以将find命令返回的文件列表传递给cat命令，但从技术上讲，并非所有方法都使用管道，也没有一种方法实际上直接通过管道传递给cat。

The simplest is to use backticks (`): cat `find [whatever]` This takes the output of find and effectively places it on the command line of cat. This doesn't work well if find has too much output (more than can fit on a command-line) or if the output has special characters (like spaces). In some shells, including bash, one can use $() instead of backticks : cat $(find [whatever]) This is less portable, but is nestable. Aside from that, it has pretty much the same caveats as backticks. Because running other commands on what was found is a common use for find, find has an -exec action which executes a command for each file it finds: find [whatever] -exec cat {} \; The {} is a placeholder for the filename, and the \; marks the end of the command (It's possible to have other actions after -exec.) This will run cat once for every single file rather than running a single instance of cat passing it multiple filenames which can be inefficient and might not have the behavior you want for some commands (though it's fine for cat). The syntax is also a awkward to type -- you need to escape the semicolon because semicolon is special to the shell! Some versions of find (most notably the GNU version) let you replace ; with + to use -exec's append mode to run fewer instances of cat: find [whatever] -exec cat {} + This will pass multiple filenames to each invocation of cat, which can be more efficient. Note that this is not guaranteed to use a single invocation, however. If the command line would be too long then the arguments are spread across multiple invocations of cat. For cat this is probably not a big deal, but for some other commands this may change the behavior in undesirable ways. On Linux systems, the command line length limit is quite large, so splitting into multiple invocations is quite rare compared to some other OSes. The classic/portable approach is to use xargs: find [whatever] | xargs cat xargs runs the command specified (cat, in this case), and adds arguments based on what it reads from stdin. Just like -exec with +, this will break up the command-line if necessary. That is, if find produces too much output, it'll run cat multiple times. As mentioned in the section about -exec earlier, there are some commands where this splitting may result in different behavior. Note that using xargs like this has issues with spaces in filenames, as xargs just uses whitespace as a delimiter. The most robust, portable, and efficient method also uses xargs: find [whatever] -print0 | xargs -0 cat The -print0 flag tells find to use \0 (null character) delimiters between filenames, and the -0 flag tells xargs to expect these \0 delimiters. This has pretty much identical behavior to the -exec...+ approach, though is more portable (but unfortunately more verbose).

Piping to another process (although this won't accomplish what you said you are trying to do): command1 | command2 This will send the output of command1 as the input of command2. -exec on a find (this will do what you want to do, but it's specific to find): find . -name '*.foo' -exec cat {} \; 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. Send output of one process as command line arguments to another process: command2 `command1` For example: cat `find . -name '*.foo' -print` Note these are backquotes not regular quotes (they are under the tilde ~ on my keyboard). This will send the output of command1 into command2 as command line arguments. It's called command substitution. Note that file names containing spaces (newlines, etc) will be broken into separate arguments, though.

列出并查看服务器上/ghi和/jkl目录下所有abc.def文件的内容

find /ghi /jkl -type f -name abc.def 2> /dev/null -exec ls {} \; -exec cat {} \;

要列出带有注释条目的abc.def文件并显示，请查看目录/ghi和/jkl中的这些条目

find /ghi /jkl -type f -name abc.def 2> /dev/null -exec grep -H ^# {} \;

find命令有一个-exec参数，你可以用它来做类似的事情，你可以直接用它来做grep。

例如(从这里，其他好的例子在本页):

find . -exec grep "www.athabasca" '{}' \; -print 

为了实现这一点(使用bash)，我将这样做:

cat $(find . -name '*.foo')

这就是所谓的“命令替换”，它在默认情况下去掉换行，这真的很方便!

这对我很有用

find _CACHE_* | while read line; do
    cat "$line" | grep "something"
done
