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
其他回答
find . -type f -exec cat {} \; -print
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
缺失的awk解是:
$ awk '(FNR==1){print ">> " FILENAME " <<"}1' *
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。
