Linux issue: Crontab a problem with relative paths when executing shell scripts, not recognized.

Problem Description: The direct execution shell script in Linux can find the file with a relative path, but if you execute the shell script through the scheduled task crontab, you cannot find the file by relative path!

Example:

Shell script file Code ~

#! /bin/sh'./1.txt'; Date >> $Logfile; Echo ' ------ ';

Execute the shell script directly, you can see the result in the 1.txt file, but if the task is executed with crontab, it will not be seen in the 1.txt execution result. Change to an absolute path, the code is as follows

#！ /bin/sh= 'pwd'/1.txt'; Date >> $Logfile; Echo ' ----- ';
