Concat使用SED的多個文件

Question

我有一個包含文件路徑的文件名列表的txt文件。如何將所有文件連接到單個文件？

EX：

One.txt content >> first file content 
two.txt content >> second file content 
three.txt content >> third file content 

allFiles.txt contains these the below lines 
one.txt 
two.txt 
three.txt 

我需要Concat的allFiles.txt到包含一個output.txt的文件，下面的線

first file content 
second file content 
third file content 

Answer 1

while read fname 
do 
sed '1' "$fname" >> newfile.txt # You need to append so '>>' 
done<allFiles.txt 

但是如果你需要的所有文件*.txt

它可以很簡單

shopt -s globstar 
sed '' **/*.txt 1>>/outfile 2>/dev/null # errors for .txt directories are suppressed 
shopt -u globstar
