Looping through the content of a file in Bash

Question

How do I iterate through each line of a text file with Bash?

With this script:

echo \"Start!\"
for p in (peptides.txt)
do
    echo \"${p}\"
done

I like to use xargs instead of while. xargs is powerful and command line friendly

cat peptides.txt | xargs -I % sh -c "echo %"

With xargs, you can also add verbosity with -t and validation with -p
