在bash脚本中逐行读取 [英] Read line by line in bash script

问题描述

我想执行以下操作，逐行读取文件，并将每行的值用作参数

I want to do the following, read line by line of a file and use the value per line as params

FILE="cat test"
echo "$FILE" | \
while read CMD; do
echo $CMD
done

但是当我执行echo $ CMD时，它只返回cat:S

but when I do the echo $CMD, it just returns cat :S

推荐答案

您所拥有的是将文本"cat test"传递到循环中.

What you have is piping the text "cat test" into the loop.

您只想要:

cat test | \
while read CMD; do
    echo $CMD
done
