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

"foreach" is not the name for bash. It is simply "for". You can do things in one line only like:

for fn in `cat filenames.txt`; do cat "$fn"; done
