else echo "Strings are not equal." fi 2. 使用 tr 命令去除所有空白字符 代码语言:txt 复制 string1=$(echo "your_string" | tr -d '[:space:]') string2=$(echo "your_string" | tr -d '[:space:]') if [ "$string1" == "$string2" ]; then echo "Strings are equal." else echo...
if [ "$str1" != "$str2" ]; then echo "Strings are not equal" else echo "Strings are equal" fi 字符串为空比较:可以使用双等号(==)来比较一个字符串是否为空。例如: 代码语言:txt 复制 str="" if [ "$str" == "" ]; then echo "String is empty" else echo "String is not empty"...
String1 and String2 are equal. String1 and String3 are not equal. 这里,如果我们先用 = 运算符比较 String1 和 String2。由于 String1 和 String2 都具有相同的长度,具有相同的字符序列,比较运算符返回 true,因此我们得到 String1 and String2 are equal.. 作为程序中第一个 if-else 块的输出。 同样...
string2="oranges" if [ "$string1" = "$string2" ]; then echo "The two strings are equal." else echo "The two strings are not equal." fi 这是我们执行脚本时的结果: $ ./test.sh The two strings are not equal. 例2 我们还可以使用运算符来测试两个字符串是否不相等!=。 #!/bin/bash...

-le:是否小于等于; 小于等于,全拼为less equal 字符串表达式: ==:是否等于; >:是否大于; <:是否小于; !=:是否不等于; =~:左侧字符串是否能够被右侧的PATTERN所匹配; Note:此表达式一般用于` `中; -z "STRING":测试字符串是否为空,空则为真,不空则为假; ...
str1 - the first String, may be null 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" ] ...
如果相等,则输出"Strings are equal",否则输出"Strings are not equal"。 接下来,让我们来看看如何在Bash中使用正则表达式进行字符串匹配。我们可以使用"=~"符号来进行正则表达式匹配,例如: bash. #!/bin/bash. str="hello world" if [[ $str =~ [0-9] ]]; then. echo "String contains a number" ...
The two strings are not equal. 1. 2. 例2 我们还可以使用运算符来测试两个字符串是否不相等!=。 #!/bin/bash string1="apples" string2="oranges" if [ "$string1" != "$string2" ]; then echo "Strings are different." else echo "Strings are not different." ...
Checking if two Bash script strings are equal isn’t a big thing per se, and even if the Bash script strings are not equal, that’s not also a big thing. This article explains everything you need to know about Bash string equality, plus how you can access and use Linux files on Win...
