我尝试过类似的事情：
grep "May ,25" $1
用户输入的文件名在哪里$1。基本上，它应该找到包含日期 5 月 25 日的行，但它什么也没显示。我知道确实有包含日期 5 月 25 日的行。
我也尝试了以下操作，但仍然不起作用：
grep "\"May\" ,25" $1
我究竟做错了什么？
答案1
引号也是字符 - 您的文件不包含May,25，它包含"May",25。所以
grep '"May",25' "$1"
或者
grep "\"May\",25" "$1"
（但不是 grep "\"May\" ,25" "$1"- 空格也是字符）。
或者您可以使用能够理解 CSV 引用的 CSV 感知工具：
mlr --csv filter 'Month == "May" && Day == 25'
csvgrep -c Month -m May "$1" | csvgrep -c Day -m 25
