我想将多个文本文件连接到终端中的一个大文件。我知道我可以使用cat命令来做到这一点。但是,我希望每个文件的文件名在该文件的“数据转储”之前。有人知道怎么做吗?

我目前拥有的:

file1.txt = bluemoongoodbeer

file2.txt = awesomepossum

file3.txt = hownowbrowncow

cat file1.txt file2.txt file3.txt

期望的输出:

file1

bluemoongoodbeer

file2

awesomepossum

file3

hownowbrowncow

如果你想用其他东西替换那些丑陋的==> <==

tail -n +1 *.txt | sed -e 's/==>/\n###/g' -e 's/<==/###/g' >> "files.txt"

解释:

Tail -n +1 *.txt -输出带头文件夹中的所有文件

sed - e ' s / = = > / \ n # # # / g - e ' s / < = = / # # # / g - = = >替换为新行< = = + # # #和# # #

>> "files.txt" -输出所有文件

这也可以做到:

$ find . -type f -print -exec cat {} \;
./file1.txt
Content of file1.txt
./file2.txt
Content of file2.txt

下面是对命令行参数的解释:

find    = linux `find` command finds filenames, see `man find` for more info
.       = in current directory
-type f = only files, not directories
-print  = show found file
-exec   = additionally execute another linux command
cat     = linux `cat` command, see `man cat`, displays file contents
{}      = placeholder for the currently found filename
\;      = tell `find` command that it ends now here

您还可以通过布尔运算符组合搜索,如-and或-or。找到-ls也很好。

我用grep来做类似的事情:

grep "" *.txt

它不会给你一个“标题”,而是给每一行加一个文件名前缀。

我喜欢这个选项

for x in $(ls ./*.php); do echo $x; cat $x | grep -i 'menuItem'; done

输出如下所示:

./debug-things.php
./Facebook.Pixel.Code.php
./footer.trusted.seller.items.php
./GoogleAnalytics.php
./JivositeCode.php
./Live-Messenger.php
./mPopex.php
./NOTIFICATIONS-box.php
./reviewPopUp_Frame.php
            $('#top-nav-scroller-pos-<?=$active**MenuItem**;?>').addClass('active');
            gotTo**MenuItem**();
./Reviews-Frames-PopUps.php
./social.media.login.btns.php
./social-side-bar.php
./staticWalletsAlerst.php
./tmp-fix.php
./top-nav-scroller.php
$active**MenuItem** = '0';
        $active**MenuItem** = '1';
        $active**MenuItem** = '2';
        $active**MenuItem** = '3';
./Waiting-Overlay.php
./Yandex.Metrika.php

为了解决这个问题,我通常使用以下命令:

$ cat file{1..3}.txt >> result.txt

如果文件数量很大,这是一种非常方便的连接文件的方法。

find . -type f -exec cat {} \; -print
