脚本好乱，请高手帮忙看下

yulong8404

#!/bin/bash


lab01=`df |grep '/var'|awk '{print $1}'`
lab02=`echo $lab01|awk -F / '{print "\\\/"$2"\\\/"$3}'`
REP01=`awk '{print $2}' /etc/fstab |grep "/var"`
REP02=`awk '{if($1~/LABEL=\/var/)print $1}' /etc/fstab`
REP03=`echo $REP02|awk -F = '{print $1"=\\\/var"}'`

if [ "/var" == $REP01 ]; then
sed -i 's/'$REP03'/'$lab02'/g' /etc/fstab
fi

lab=`df |grep '/$'|awk '{print $1}'`
lab1=`echo $lab|awk -F / '{print "\\\/"$2"\\\/"$3}'`
REP1=`awk '{print $2}' /etc/fstab |grep "/$"`
REP2=`awk '{if($1~/LABEL=\/1$/)print $1}' /etc/fstab`
REP3=`echo $REP2|awk -F = '{print $1"=\\\/1"}'`

REP5=`awk '{if($1~/LABEL=\/$/)print $1}' /etc/fstab`
REP6=`echo $REP5|awk -F = '{print $1"=\\\/"}'`
if [ "LABEL=/1" == $REP2 ]; then
sed -i 's/'$REP3'/'$lab1'/g' /etc/fstab
else if [ "LABEL=/" == $REP5 ]; then
sed -i 's/'$REP6'/'$lab1'/g' /etc/fstab
fi
fi



这个脚本写的有点乱，有什么办法能弄的简单明了的吗？

R ...

把几个变量分别打印出来看下就不乱了吧
