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

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。

其他回答

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。

这应该可以达到目的:

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

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

我做了一个组合:

Cat /sharedpath/{unique1,unique2,unique3}/filename >新文件

and

Tail -n +1 file1 file2

到这个:

Tail -n +1 /sharedpath/{folder1,folder2,…,folder_n}/文件。扩展名| cat > /sharedpath/newfile

结果是一个newfile,其中包含{}括号中每个子文件夹(unique1,unique2..)的内容,以子文件夹名称分隔。

注意unique1 = folder1

在我的例子中是文件。扩展名在所有子文件夹中具有相同的名称。

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 ...

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
