Script for directory file backup using shell position variables

Today only found that the original position variable can also play so cool!!

This is a file directory backup using the location variable:

#!/bin/bash

Date= ' Date +%f '//date output from year to month

Tar Czf $ $DATE. tar.gz $ >/dev/null 2>>/opt/$1.bak.log//pack variable package, append error to log, tar package will keep original directory, better

If [$?-eq 0] The return value is 0 for packing OK, not 0, not OK

Then #包 time pack OK append to log

echo "$ $DATE backup successfully" >>/opt/$1.bak.log

Else #包 time Package not OK append to log

echo "$ $DATE backup failed" >>/opt/$1.bak.log

Fi
