猫多个文件，但包括文件名作为头

I would like to concatenate a number of text files into one large file in terminal. I know I can do this using the cat command. However, I would like the filename of each file to precede the "data dump" for that file. Anyone know how to do this?

我想把一些文本文件连接到终端的一个大文件中。我知道我可以用cat命令。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?

what I currently have:

我目前拥有的:

file1.txt = bluemoongoodbeer

file2.txt = awesomepossum

file3.txt = hownowbrowncow

cat file1.txt file2.txt file3.txt

desired output:

期望的输出:

file1

bluemoongoodbeer

file2

awesomepossum

file3

hownowbrowncow

Was looking for the same thing, and found this to suggest:

我也在寻找同样的东西，发现这表明:

tail -n +1 file1.txt file2.txt file3.txt

Output:

输出:

==> file1.txt <==
<contents of file1.txt>

==> file2.txt <==
<contents of file2.txt>

==> file3.txt <==
<contents of file3.txt>

If there is only a single file then the header will not be printed. If using GNU utils, you can use -v to always print a header.

如果只有一个文件，那么头文件将不会被打印。如果使用GNU utils，您可以使用-v来始终打印标题。

#2

I used grep for something similar:

我用grep做了类似的事情:

grep "" *.txt

It does not give you a 'header', but prefixes every line with the filename.

它没有给你一个“标题”，但是在每一行都加上文件名。

#3

This should do the trick as well:

这一招也应该奏效:

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

Means:

意思是:

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

You further can combine searches trough boolean operators like -and or -or. find -ls is nice, too.

您还可以通过布尔运算符(如-or -or)组合搜索。查找-ls也很好。

#4

This should do the trick:

这应该能达到目的:

for filename in file1.txt file2.txt file3.txt; do
    echo "$filename"
    cat "$filename"
done > output.txt

or to do this for all text files recursively:

或者递归地对所有文本文件执行此操作:

find . -type f -name '*.txt' -print | while read filename; do
    echo "$filename"
    cat "$filename"
done > output.txt

#5

find . -type f -print0 | xargs -0 -I % sh -c 'echo %; cat %'

This will print the full filename (including path), then the contents of the file. It is also very flexible, as you can use -name "expr" for the find command, and run as many commands as you like on the files.

这将打印完整的文件名(包括路径)，然后是文件的内容。它也非常灵活，因为您可以对find命令使用-name“expr”，并在文件中运行任意多的命令。

#6

I had a series of files that ended in stats.txt that I wanted to concatenate with the filenames.

我有一系列以stats结尾的文件。我想要连接到文件名的txt。

I did the following and when there is more than one file, the "more" command includes the filename as a header.

我做了以下操作，当有多个文件时，“more”命令包括文件名作为标题。

more *stats.txt > stats.txt

or for a general case

或者一般情况下。

more FILES_TO_CONCAT > OUTPUT_FILE

#7

This is how I normally handle formatting like that:

我通常是这样处理格式的:

for i in *; do echo "$i"; echo ; cat "$i"; echo ; done ;

I generally pipe the cat into a grep for specific information.

我通常会把这只猫放进一个grep中以获取特定的信息。

#8

you can use this simple command instead of using a for loop,

您可以使用这个简单的命令而不是使用for循环，

ls -ltr | awk '{print $9}' | xargs head

#9

I like this option

我喜欢这个选项

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

Output looks like this:

输出是这样的:

./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

Here is a really simple way. You said you want to cat, which implies you want to view the entire file. But you also need the filename printed.

这里有一个非常简单的方法。您说您想要cat，这意味着您想查看整个文件。但是您还需要打印文件名。

Try this

试试这个

head -n99999999 * or head -n99999999 file1.txt file2.txt file3.txt

头-n99999999 *或头-n99999999 file1。txt file2。txt file3.txt

Hope that helps

希望这有助于

If you like colors, try this:

如果你喜欢颜色，试试这个:

for i in *; do echo; echo $'\e[33;1m'$i$'\e[0m'; cat $i; done | less -R

or:

或者:

tail -n +1 * | grep -e $ -e '==.*'

or: (with package 'multitail' installed)

或:(已安装'multitail'软件包)

multitail *

#12

This method will print filename and then file contents:

此方法将打印文件名，然后文件内容:

tail -f file1.txt file2.txt

Output:

输出:

==> file1.txt <==
contents of file1.txt ...
contents of file1.txt ...

==> file2.txt <==
contents of file2.txt ...
contents of file2.txt ...

#13

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

#14

If you want the result in the same format as your desired output you can try:

如果你想要结果的格式与你想要的输出相同，你可以尝试:

for file in `ls file{1..3}.txt`; \
do echo $file | cut -d '.' -f 1; \ 
cat $file  ; done;

Result:

结果:

file1
bluemoongoodbeer
file2
awesomepossum
file3
hownowbrowncow

You can put echo -e before and after the cut so you have the spacing between the lines as well:

你可以在切割前后加上echo -e，这样你就有了线条之间的间距:

$ for file in `ls file{1..3}.txt`; do echo $file | cut -d '.' -f 1; echo -e; cat $file; echo -e  ; done;

Result:

结果:

file1

bluemoongoodbeer

file2

awesomepossum

file3

hownowbrowncow

... glomming onto those who've already mentioned head works for some of us:

…对那些已经提到过head的人说:

$ r head
head file*.txt
==> file1.txt <==
xxx
111

==> file2.txt <==
yyy
222
nyuk nyuk nyuk

==> file3.txt <==
zzz
$

My need is to read the first line; as noted, if you want more than 10 lines, you'll have to add options (head -9999, etc).

我需要读第一行;如前所述，如果您想要超过10行，您必须添加选项(head -9999，等等)。

Sorry for posting a derivative comment; I don't have sufficient street cred to comment/add to someone's comment.

对不起，我发布了一个衍生评论;我没有足够的信誉来评论/添加到某人的评论中。

#16

For solving this tasks I usually use the following command:

为了完成这个任务，我通常使用以下命令:

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

It's a very convenient way to concatenate files if the number of files is quite large.

如果文件的数量很大，这是连接文件的一种非常方便的方式。
