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

缺失的awk解是:
$ awk '(FNR==1){print ">> " FILENAME " <<"}1' *
其他回答
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
这是我通常如何处理这样的格式:
for i in *; do echo "$i"; echo ; cat "$i"; echo ; done ;
我通常将cat管道到grep中以获取特定的信息。
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
这里有一个非常简单的方法。您说您想cat，这意味着您想查看整个文件。但是你还需要打印文件名。
试试这个
Head -n99999999 *或Head -n99999999 file1.txt file2.txt file3.txt
希望这能有所帮助
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。
