awk 小运用

#

#实现字符串的获取和截断，详细看运行的例子

#!/bin/bash

if [ $# -le 0 ] ;

then
  echo "Usage:`basename $0` format:a=b?c=d..."
else
str=`echo $* | awk -F"?" '{for(i=1;i<=NF;i++){print $i} }'`
echo $str
count=`echo $str | awk -F" " '{print NF}'`
echo $count
i=1
while [ "$i" -le "$count" ]
do
userid_=`echo $str | awk -F" " '{print $1 } ' | cut -d "=" -f1`
userpass_=`echo $str | awk -F" " '{print $1}' |cut -d "=" -f2`
echo "key: ${userid_}" #key

echo "values: ${userpass_}" #value

#echo $str

str=`echo $str | sed -e "s;${userid_}=${userpass_};;"` #cut the str,util str'slength =0

i=`expr $i + 1`
done
fi

例子如下所示：


[oracle@linux3 shll]$ sh temp.sh name=nsss?user=sdddd? id="dldlf"
name=nsss user=sdddd id=dldlf
3
key: name
values: nsss
key: user
values: sdddd
key: id
values: dldlf
