这基本上就是我的脚本。
#!/bin/sh
#set -x
PATH=/usr/jdk/instances/current/bin:/usr/bin:/bin:/opt/ss7/access/bin:/opt/ss7/sgc/bin:/opt/ss7/access/install:/opt/ss7/sgc/install:/usr/jdk/instances/current/bin:/bin:/usr/bin:/usr/local/bin:/usr/sbin:/usr/ccs/bin:/usr/openwin/bin:/usr/ucb:/opt/stg/5.0/bin:/opt/stg/5.0/tools
/opt/stg/5.0/bin/ctl status all > stgstatus.txt
MINUTE=`cat stgstatus.txt |grep traffic |awk '{print $2}' |cut -d"|" -f1`
if [ $MINUTE -eq 0 ];then
/opt/stg/5.0/bin/ctl restart all
fi
但是当 crontab 尝试运行它时，它总是会出现此错误。我的脚本中没有任何whoami命令，为什么会出现错误？

这就是我的 crontab 的样子。
