This way :

<pre><code>find . -type f -name "*.csv" -exec sed -i '1icolumn1,column2,column3' {} +
</code></pre>

<code>-exec</code> do all the magic here. The relevant part of <code>man find</code> :

<pre><code> -exec command ;
 Execute command; true if 0 status is returned. All following arguments
 to find are taken to be arguments to the command until an argument consisting
 of `;' is encountered. The string `{}' is replaced by the current file name
 being processed everywhere it occurs in the arguments to the command, not just
 in arguments where it is alone, as in some versions of find. Both of 
 these constructions might need to be escaped (with a `\') or quoted to protect
 them from expansion by the shell. See the EXAMPLES section for examples of
 the use of the -exec option. The specified command is run once for each
 matched file. The command is executed in the starting directory. There
 are unavoidable security problems surrounding use of the -exec action;
 you should use the -execdir option instead
</code></pre>

Try using <code>xargs</code> to pass output of <code>find</code> and command line arguments to next command, here <code>sed</code>

<pre><code>find . -type f -name '*.csv' -print0 | xargs -0 sed -i '1icolumn1,column2,column3'
</code></pre>

<hr>

Another option would be to use <code>-exec</code> option of <code>find</code>.

<pre><code>find . -type f -name '*.csv' -exec sed -i '1icolumn1,column2,column3' {} \;
</code></pre>

<hr>

Note : It has been observed that <code>xargs</code> is more efficient way and can handle multiple processes using <code>-P</code> option.

I want to insert a line into the start of multiple specified type files, which the files are located in current directory or the sub dir.

I know that using

<pre><code>find . -name "*.csv"
</code></pre>

can help me to list the files I want to use for inserting.

and using

<pre><code>sed -i '1icolumn1,column2,column3' test.csv
</code></pre>

can use to insert one line at the start of file,

but now I do NOT know how to pipe the filenames from "find" command to "sed" command.

Could anybody give me any suggestion?

Or is there any better solution to do this?

BTW, is it work to do this in one line command?

Insert line into multi specified files

我想在多个指定类型文件的开头插入一行，这些文件位于当前目录或子目录中。我知道用find . -name "*.csv"可以帮助我列出我想要插入的文件。并使用sed -i '1icolumn1,column2,column3' test.csv可用于在文件开头插入一行，但是现在我不知道如何将文件名从"find“命令传递到...
