脚本可以手动正常运行，但不能在crontab上运行

Question

My script is working manually but not working on crontab.I read all topics about this issue I tried so many things to execute via crontab but didnt work.

My script is below.

#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
nodetool status > cqlsh_control.txt
cs1=`more cqlsh_control.txt | awk '{print $1}' | sed -ne 6p | cut -d"%" -f1`
SLACK_ICON=":red_circle:"
if [ "$cs1" != "UN" ]; then

curl -S -X POST --data "payload={\"text\": \"{Cqlsh is not responsing Cassandra2}  \",\"username\":\"CQLSH\",\"icon_emoji\":\"${SLACK_ICON}\"
}" https://hooks.slack.com/services/T05xxxxW/B7xxxxxx09/QdotCzoxxxxxxxHxOsrnjS
