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' *

当有多个输入文件时，more命令将它们连接起来，并将每个文件名作为头文件。
连接到一个文件:
more *.txt > out.txt
连接到终端:
more *.txt | cat
示例输出:
::::::::::::::
file1.txt
::::::::::::::
This is
my first file.
::::::::::::::
file2.txt
::::::::::::::
And this is my
second file.
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
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。
这个方法将先打印文件名，再打印文件内容:
tail -f file1.txt file2.txt
输出:
==> file1.txt <==
contents of file1.txt ...
contents of file1.txt ...
==> file2.txt <==
contents of file2.txt ...
contents of file2.txt ...
find . -type f -exec cat {} \; -print
