输出: Not equal 表达式中的 Bash if not 条件 我们可以使用! [[]] 之外的运算符使整个表达式的输出为负数。我们不能在双方括号内进行操作以使单个表达式为负数。让我们看一个例子。 #!/bin/bash n=4 if ! [[ $n -eq 0 ]]; then echo "Not equal to 0" fi 输出: Not equal to 0 相关...
Bash 中整数情况下的if not条件 我们可以使用-ne来检查两个整数变量之间的不等式。让我们看一个例子。 #!/bin/bashx=5y=4if[[$x-ne$y]];thenecho"Not equal"fi 输出: Not equal Bash 中字符串的if not条件 我们可以使用!=运算符来比较两个字符串。 #!/bin/bashsone=Binstwo=Bashif[[$sone!=$stw...
not equal to, less than, less than or equal to, greater than, or greater than or equal to “ARG2”, respectively. “ARG1” and “ARG2” are integers.
[ STRING1 > STRING2 ] 如果 “STRING1” sorts after “STRING2” lexicographically in the current locale则为真。 [ ARG1 OP ARG2 ] “OP” is one of -eq, -ne, -lt, -le, -gt or -ge. These arithmetic binary operators return true if “ARG1” is equal to, not equal to, less than,...
These arithmetic binary oprators return true if“arg1”is equal to,not equal to,less than,less than or equal to,greater than,or greater than or equal to“agr2”,respectively.“arg1”and “agr2”are integers. 3、注意事项 代码语言:javascript 代码运行次数:0 运行 AI代码解释 if [ x${var} ...

For this, we need to utilize the not operator “!” with the “if” statement in the bash script. Let’s discuss the use of the “if-not” operator in Bash programming with the help of some examples. Get started with the new Bash file creation while using the terminal shell of the ...
/bin/bash num1=10 num2=20 if [ $num1 -gt $num2 ] then echo “$num1 is greater than $num2.” elif [ $num1 -eq $num2 ] then echo “$num1 is equal to $num2.” else echo “$num1 is less than $num2.” fi “`
echo “f is not less than or equal to 80.” fi “` 三、字符串比较 在Linux命令行中,我们可以使用双等号(==)运算符进行字符串比较。以下代码判断两个字符串是否相等: “`bash #!/bin/bash str1=”hello” str2=”world” if [ $str1 == $str2 ] ...
Use if statement in bash Let's create a script that tells you if a given number is even or not. Here's my script namedeven.sh: #!/bin/bash read -p "Enter the number: " num mod=$(($num%2)) if [ $mod -eq 0 ]; then ...
