The Ifconfig command in the Linux crontab call script returns to null

#!/bin/bash

Ip= "' Ifconfig eth0|awk-f" [:]+ "' nr==2 {print $4} ' _$ (date%f%h%m)"

Execution of the script through SH is normal, and the crontab scheduled task call is NULL,

*/1 * * * */bin/sh/scripts/tar.sh >/dev/null 2>&1

Workaround:

Solve the problem of changing the ifconfig in the script to the perfect path/sbin/ifconfig

Ip= "'/sbin/ifconfig eth0|awk-f" [:]+ "' nr==2 {print $4} ' _$ (date%f%h%m)"
