Linux: Merging multiple files, each on a new line
提问by Marco
I am using cat *.txtto merge multiple txt files into one, but I need each file to be on a separate line.
我正在使用cat *.txt将多个 txt 文件合并为一个，但我需要每个文件都在单独的行上。
What is the best way to merge files with each file appearing on a new line?
合并每个文件出现在新行上的最佳方法是什么？

If you have a pastethat supports it,
如果你有一个paste支持它，
paste --delimiter=\n --serial *.txt
does a really great job
做得很好

You can iterate through each file with a for loop:
您可以使用 for 循环遍历每个文件：
for filename in *.txt; do
# each time through the loop, ${filename} will hold the name
# of the next *.txt file. You can then arbitrarily process
# each file
cat "${filename}"
echo
# You can add redirection after the done (which ends the
# for loop). Any output within the for loop will be sent to
# the redirection specified here
done > output_file

I'm assuming you want a line break between files.
我假设你想在文件之间换行。
for file in *.txt
do
cat "$file" >> result
echo >> result
done

for file in *.txt
do
cat "$file"
echo
done > newfile
