First of all, your crontab entry does not schedule every 38 minutes:

Code:
38 * * * * /your/crontab/script.sh

That crontab entry executes at 38 minutes after the hour, every hour.

There are many examples of how to write a crontab entry in the man pages.

For example on linux:

https://www.unix.com/man-page/linux/5/crontab/


Quote:
EXAMPLE CRON FILE

Code:
# use /bin/bash to run commands, instead of the default /bin/sh
       SHELL=/bin/bash
       # mail any output to `paul', no matter whose crontab this is
       MAILTO=paul
       #
       # run five minutes after midnight, every day
       5 0 * * *       $HOME/bin/daily.job >> $HOME/tmp/out 2>&1
       # run at 2:15pm on the first of every month -- output mailed to paul
       15 14 1 * *     $HOME/bin/monthly
       # run at 10 pm on weekdays, annoy Joe
       0 22 * * 1-5    mail -s "It's 10pm" joe%Joe,%%Where are your kids?%
       23 0-23/2 * * * echo "run 23 minutes after midn, 2am, 4am ..., everyday"
       5 4 * * sun     echo "run at 5 after 4 every sunday"
       # Run on every second Saturday of the month
       0 4 8-14 * *    test $(date +%u) -eq 6 && echo "2nd Saturday"

Maybe you can review the examples and repost your idea for the correct crontab entry for us to review?

I am not the "kind of guy" to post solutions for people, as I prefer to lead people to learn to think and solve problems for themselves.

If we just "give you the solution" then we are not teaching you to solve problems on your own; we are doing your work for you. We are here to teach and lead people to solutions, and to help them development themselves as unix/linux systems admins, developers, problem solvers and coders, not to do your work.
