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

If you don't want your read to be broken by newline character, use -

#!/bin/bash
while IFS='' read -r line || [[ -n "$line" ]]; do
    echo "$line"
done < "$1"

Then run the script with file name as parameter.
