重击-从文件读取行时打印第一和第二列 [英] Bash - While read line from file print first and second column

问题描述

我有一个如下的测试文件。 （但实际文件有1000多个行，并且有很多列）

I have a test file like below. (but the actual file has 1000+ lines and many columns)

apple,2
mango,5
coconut,10

我要按以下方式打印此文件。

I want to print this file as below.

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

我在读取行时尝试了 和 awk -F'，''{print $ 1}'，但是我没有得到实际输出。
有人可以帮我吗？

I tried while read line with awk -F ',' '{print $1}', but im not getting the actual output. Can someone help me on this?

推荐答案

您可以使用 awk 像这样：

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

尽管建议使用 awk ，但如果您正在寻找bash循环，则使用：

Though awk is recommended but if you are looking for a bash loop then use:

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