将上述脚本保存到一个文件中(例如compare_strings.sh),然后赋予执行权限并运行它: bash chmod +x compare_strings.sh ./compare_strings.sh 你应该会看到输出表明str1和str2是相等的。

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.

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,在第二个程序中,我们使用==运算符比较String1和String2。在这种情况下,我们需要使用[[进行比较。
