Bash + Expect脚本在cron RHEL 7中不起作用

Question

我有以下脚本，该脚本在终端中运行，但在crontab中不起作用。为什么它不在cron中运行

注意：/opt/app/bin/app.exe具有CLI

#!/bin/bash
PATH=/opt/app/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/myuser/.local/bin:/home/myuser/bin:/home/myuser/scripts

ip=10.12.13.4
file=filename

function filestats(){
        /usr/bin/expect - $1 $2 << 'EOF' | awk  '/^second line/ { print $5 }'
set ip [lindex $argv 0]
set file [lindex $argv 1]

set timeout 60

spawn /opt/app/bin/app.exe 127.0.0.1 $ip 1112

expect {
        "CLI# > " { send "addip $file
" }
}

sleep 3
expect {
        "CLI# > " { send "quit
" }
}
EOF
}
filestats ${ip} ${file}
