The job is set such that it will run 28 # forever every minute of the day. 29 # The cronjob runs a program that will print a string followed by the current 30 # date and time. Five samples are taken inorder to verify if cron job is run 31 # every minute. It is not practical to check if it works for the remaining 32 # fields of the crontab file also. 33 # 34 # Author: Manoj Iyer manjo (at] mail.utexas.edu 35 # 36 # History: 37 # Dec - 19 - 2002 - Created. 38 # Dec - 20 - 2002 - Correted Test #3, grep for the filename of cronjob 39 # after executing crontab -l. 40 # - Fixed bug in #3, test was not installing the cronjob. 41 # - Added more informational messages TINFO. 42 # - Changed permissions to this file to 'x' 43 44 export TST_TOTAL=3 45 46 if [ -z "$LTPTMP" -a -z "$TMPBASE" ] 47 then 48 LTPTMP=/tmp 49 else 50 LTPTMP=$TMPBASE 51 fi 52 53 if [ -z "$LTPBIN" -a -z "$LTPROOT" ] 54 then 55 LTPBIN=./ 56 else 57 LTPBIN=$LTPROOT/testcases/bin 58 fi 59 60 . cmdlib.sh 61 SYSLOG_STARTED=0 62 63 if [ -n "$SYSLOG_DAEMON" ]; then 64 status_daemon $SYSLOG_DAEMON 65 if [ $? -ne 0 ]; then 66 restart_daemon $SYSLOG_DAEMON 67 SYSLOG_STARTED=1 68 fi 69 fi 70 71 # Set return code RC variable to 0, it will be set with a non-zero return code 72 # in case of error.
