Bash-从文件读取行时打印第一和第二列

Question

我有一个如下的测试文件。（但实际文件有1000多行和许多列）

apple,2
mango,5
coconut,10

我要按以下方式打印此文件。

I have apple and the count is 2
I have mango and the count is 5
I have coconut and the count is 10

我尝试while read line使用awk -F ',' '{print $1}'，但即时通讯未获得实际输出。有人可以帮我吗？

Answer 1

您可以这样使用awk：

awk -F, '{print "I have", $1, "and the count is", $2}' file

I have apple and the count is 2
I have mango and the count is 5
I have coconut and the count is 10

虽然awk推荐，但如果您正在寻找bash循环，请使用：

while IFS=, read -r f c; do
    echo "I have $f and the count is $c"
done < file
