The “==” operator is used to check the equality of two bash strings. In the example below, two strings are defined: strng1 and strng2. Also, you can check Bash strings for equality using the string value; an example is below. Comparison with “!=” operators The “!=” operator ...

This will test whether the variable$foois equal to the string*ar. It will work even if$foois empty because the quotation marks will force an empty string comparison. The quotes around*arwill prevent the shell from interpolating the glob. This is a true equality. ...
bash脚本指定python版本,Shell脚本是Linux中过程自动化的重要组成部分。脚本可以帮助您在文件中编写一系列命令,然后执行它们。这节省了您的时间,因为您不必一遍又一遍地编写某些命令。您可以高效地执行日常任务,甚至可以安排它们自动执行。您还可以设置某些脚本在启动时
