在Bash中循环浏览文件内容

问题：

How do I iterate through each line of a text file with Bash ? 如何使用Bash遍历文本文件的每一行？

With this script: 使用此脚本：

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

I get this output on the screen: 我在屏幕上得到以下输出：

Start!
./runPep.sh: line 3: syntax error near unexpected token `('
./runPep.sh: line 3: `for p in (peptides.txt)'

(Later I want to do something more complicated with $p than just output to the screen.) （后来我想用$p来做一些比只输出到屏幕更复杂的事情。）
