Thank you very much Cameron and Jorge for responding. I have done this, but I
encounter the following error:
[oliva...@localhost Documents]$ cat edit-crontab
#!/bin/sh
set -ue
tmp=/tmp/crontab$$
crontab -l >"$tmp"
echo "15 16 * * 1-5 /usr/bin/poweroff >/dev/null 2>&1' >>"$tmp"
crontab "$tmp"
rm "$tmp"
[oliva...@localhost Documents]$ ./edit-crontab
./edit-crontab: line 7: unexpected EOF while looking for matching `"'
I have encountered a few errors like this one when creating other scripts, and
I have used the "`" character to help me, I will try to use it and see if it
helps me get past this error?
Thanks a million.
Regards,
Antonio
