To check if two strings are equal in a Bash script, there are two comparison operators used. First, we’ll discuss the “==” operator. The “==” operator is used to check the equality of two bash strings. In the example below, two strings are defined: strng1 and strng2. Also, ...
str2 - the second String, may be null Returns: true if the Strings are equal, case insensitive, or both null In Bash 判断字符串相等 格式1:test "$S1" = "$S2" 格式2:[ "$S1" = "$S2" ] 格式3:test "$S1" == "$S2" 格式4:[ "$S1" == "$S2" ] ...

When writing Bash scripts you will often need to compare two strings to check if they are equal or not. Two strings are equal when they have the same length and contain the same sequence of characters.
if [ "$str1" = "$str2" ]; then echo "Strings are equal." else echo "Strings are not equal." fi 输出结果 Strings are equal. 在bash中为何\n等于'n'? bash 收藏 BETA 在bash中,\n并不等于'n'。在你的示例中,出现Strings are equal.的输出,是因为在bash字符串比较中的特殊行为,但这并不...
解决方法:使用=进行严格相等性比较,或者对字符串进行引用,例如"${string1}" == "${string2}"。 示例代码 代码语言:txt 复制 #!/bin/bash string1="hello" string2="world" if [ "${string1}" = "${string2}" ]; then echo "Strings are equal." ...
