Where is the default PATH of crontab defined?

Solution Unverified - Updated -

Issue

  • If I create a cron job to show the default value of PATH of crontab:
# crontab -l
* * * * * echo $PATH >> /tmp/PATH

The result is "/usr/bin:/bin".

  • Where is the default PATH of crontab defined? Does crontab have any configuration file to define PATH?
