If the original file contains non-printable characters, they will be lost when using the cat command. Using 'cat -v', the non-printables will be converted to visible character strings, but the output file would still not contain the actual non-printables characters in the original file. With a small number of files, an alternative might be to open the first file in an editor (e.g. vim) that handles non-printing characters. Then maneuver to the bottom of the file and enter ":r second_file_name". That will pull in the second file, including non-printing characters. The same could be done for additional files. When all files have been read in, enter ":w". The end result is that the first file will now contain what it did originally, plus the content of the files that were read in.

for i in {1..3}; do cat "$i.txt" >> 0.txt; done

我找到这个页面是因为我需要将952个文件合并为一个。我发现如果你有很多文件，这个工作得更好。这将为您需要的任意数量的数字进行循环，并使用>>将每个数字附加到0.txt的末尾。

编辑:

正如评论中提到的:

cat {1..3}.txt >> 0.txt

or

cat {0..3}.txt >> all.txt

发送多个文件到一个文件(text .txt):

cat *.txt > textall.txt

如果你所有的文件名称都类似，你可以简单地这样做:

cat *.log >> output.log

如果你的文件包含头文件，你想在输出文件中删除它们，你可以使用:

for f in `ls *.txt`; do sed '2,$!d' $f >> 0.out; done
