Question

我需要在搜索单词后显示文件内容。如果找到该单词，则显示该文件。

我的代码如下：

GNU nano 2.2.6文件：工作

#!/bin/bash


while read -p "Welcome what would you like to do (S) to search or (Q) to quit  "  option
do
case $option in
        "S")    echo "What is the name of the file you would like to search for?"
                read file
                echo "What word would you like to find in the file?"
                read word
                grep -q $word $file
                if [ $? -eq 0 ]; then
                echo "$word found in $file"
                cat $file
                else
                echo "$word NOT found in $file"
                fi
                ;;

        "Q")    echo "Goodbye!"
                exit ;;

          *)    echo "invalid option" ;;
esac
done

Answer 1

替换

echo $file

与

cat $file

Answer 2

我相信你正在寻找命令cat $file。将其粘贴在if块内。

Answer 3

我需要在加载文件时加载文件所说的内容。

如果不访问该文件，则无法访问该文件的内容。

Answer 4

grep -l word file | xargs -r cat

如果找到单词，

显示文件内容。这也显示了文件名

grep -l word file | xargs -r -i bash -c "echo {}:; cat {}"

搜索完成后显示文件内容
