I have a file that contains a list of filenames on each line.
myfile.txt:
somepath/Documents/a.txt
somepath/Documents/b.txt
somepath/Documents/c.txt
This file can contain any number of lines. What I want to do is then run a command that runs cat with each line being an input, such as:
cat <line 1> <line 2> <line 3> new_combination_file.txt
I was looking this up and I think I should be using xargs to do this, but when I looked up examples and the man page, it didn't make sense to me. Can someone help?
Use a while read loop to read each line into a variable
while read -r filename
do
cat "$filename"
done < myfile.txt > new_combination_file.txt
You can also use xargs:
xargs cat < myfile.txt > new_combination_file.txt
However, this won't work if any filenames contain spaces.
