linux - 有没有办法读取文本文件并使用其中的单词作为输入？

Question

我正在处理一个任务，我必须读取文本文件并将其中的每个单词作为输入，重要的是我必须使用 while 或任何其他循环来完成它(不使用awk 命令)

我在 while 循环中尝试了它，它正在读取文件，但我无法弄清楚接下来的步骤。

详情如下:

内容文件(源文件)

[root@localhost ~]# cat content.txt
Rantndeep,old spice,100,20
D-mart,toothbrush,30,20
more,sack,300,10

要求的输出

[root@localhost ~]# sh parser.sh
Today I went to Rantndeep Store bought old spice For Rs. 100 And paid 20 Rs.as a parking charges
Today I went to D-mart Store bought toothbrush For Rs. 30 And paid 20 Rs.as a parking charges
Today I went to more Store bought sack For Rs. 300 And paid 10 Rs.as a parking charges

我的脚本

[root@localhost ~]# cat p.sh
#/bin/bash
cat content.txt | while read a
do
     echo $a
done

如上所述，这只是打印文件的内容我想通过使用任何循环编写脚本，以便我可以获得输出

[root@localhost ~]# sh parser.sh
Today I went to Rantndeep Store bought old spice For Rs. 100 And paid 20 Rs.as a parking charges
Today I went to D-mart Store bought toothbrush For Rs. 30 And paid 20 Rs.as a parking charges
Today I went to more Store bought sack For Rs. 300 And paid 10 Rs.as a parking charges

Answer 1

您快完成了。请注意，您可以使用 read 设置多个变量。尝试

IFS=, # Because you separate the items using comma instead of space
while read w1 w2 w3 w4
do
  echo "first word: $w1  second word: $w2  last word: $w4"
done < content.txt

您将看到在每次迭代中，w1... w4 包含 content.txt 中相应行的 4 个字段
