1 # Edit this file to introduce tasks to be run by cron.
2 #
3 # Each task to run has to be defined through a single line
4 # indicating with different fields when the task will be run
5 # and what command to run for the task
6 #
7 # To define the time you can provide concrete values for
8 # minute (m), hour (h), day of month (dom), month (mon),
9 # and day of week (dow) or use '*' in these fields (for 'any').#
10 # Notice that tasks will be started based on the cron's system
11 # daemon's notion of time and timezones.
12 #
13 # Output of the crontab jobs (including errors) is sent through
14 # email to the user the crontab file belongs to (unless redirected).
15 #
16 # For example, you can run a backup of all your user accounts
17 # at 5 a.m every week with:
18 # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
19 #
20 # For more information see the manual pages of crontab(5) and cron(8)
21 #
22 # m h dom mon dow command
23 0 5 * * 1 /home/user/bin/checkSystem
스크립트는 다음과 같습니다.

어떻게 되어가나요?
편집하다:
(root@host)-(20:39:01)-(/home/user)
$which logwatch
/usr/sbin/logwatch
(root@host)-(20:39:06)-(/home/user)
$which chkrootkit
/usr/sbin/chkrootkit
(root@host)-(20:39:16)-(/home/user)
$which rkhunter
/usr/bin/rkhunter
(root@host)-(20:39:22)-(/home/user)

답변1
cronjob이 실행되면 'logwatch'를 찾을 수 없습니다. Logwatch가 설치되어 있으므로 이는 경로에서 누락되었음을 의미할 수 있습니다. /etc/crontab 파일의 PATH에 "/usr/sbin"을 추가하면 이 문제를 해결할 수 있습니다.
/etc/crontab을 편집할 권한이 없는 경우 이 문제를 해결하는 또 다른 방법은 스크립트에서 직접 실행 파일의 전체 경로를 사용하는 것입니다.
