Bash foreach loop

Question

I have an input (let\'s say a file). On each line there is a file name. How can I read this file and display the content for each one.

Answer 1

Something like this would do:

xargs cat 

The xargs program reads its standard input, and for each line of input runs the cat program with the input lines as argument(s).

If you really want to do this in a loop, you can:

for fn in `cat filenames.txt`; do
    echo "the next file is $fn"
    cat $fn
done
