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

如果你想要的结果与你想要的输出格式相同,你可以尝试:

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

结果:

file1
bluemoongoodbeer
file2
awesomepossum
file3
hownowbrowncow

你可以在剪切之前和之后加上echo -e,这样你就有了行与行之间的间距:

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

结果:

file1

bluemoongoodbeer

file2

awesomepossum

file3

hownowbrowncow

你可以使用这个简单的命令来代替for循环,

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

也在寻找同样的东西,发现这表明

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

输出:

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

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

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

如果只有一个文件,则不会打印头文件。如果使用GNU utils,您可以使用-v始终打印头文件。

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

如果你想要的结果与你想要的输出格式相同,你可以尝试:

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

结果:

file1
bluemoongoodbeer
file2
awesomepossum
file3

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。
