Thank you, so you can look up to the test. The TXT path, but to tell if the file exists, to what kind of instruction?

CodePudding user response:

Find no means there is no

CodePudding user response:

Just try and find whether have found, the return value is 0.
So use & gt; The find results lead to the log file, and then use the grep judgment is ok.
