str1="Hello" str2="World" 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 [ "$str" == "" ]; then echo "String is empty" els...
if [[ "$String1" != "$String3" ]]; then echo "String1 and String3 are not equal." else echo "String1 and String3 are equal." fi 输出: String1 and String2 are equal. String1 and String2 are equal. String1 and String3 are not equal. 这里,如果我们先用 = 运算符比较 String1 ...
if [ "$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 关注收藏 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...

[ 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...
