That's better
这样更好
cat myfile.txt | while read line; do
echo "$line"
done
or even better (doesn't launch other processes such as a subshell and cat):
甚至更好（不启动其他进程，例如子shell和cat）：
while read line; do
echo "$line"
done < myfile.txt
If you prefer oneliners, it's obviously
如果你更喜欢oneliners，那显然是
while read line; do echo "$line"; done < myfile.txt
