bash - 如何在 bash shell 脚本变量中查找子字符串

Question

我有一个如下所示的变量。

variable = This script is not found

if [[ "$variable" = ~ "not found" ]];
then
echo "Not Found"
else
echo "Its there"
if

在执行 im 时低于错误，

line 4: syntax error in conditional expression
./test.sh: line 4: syntax error near `found"'
./test.sh: line 4: `if [[ "$variable" = ~ "not found" ]]; '

谁能指出我，我在这里缺少什么？

Answer 1

LIST="some string with a substring you want to match"
SOURCE="substring"

if echo "$LIST" | grep -q "$SOURCE"; then
    echo "matched";
else
    echo "no match";
fi

祝你好运;)
