zdb命令提取文件shell脚本

shell脚本内容（文件比较大时会很慢）：

#!/bin/bash
echo "readzfsobj.sh <poolname> <objectid> <outfile>"
touch $3
#zdb -ddddd $1/ $2 |sed -n "/^  *[0123456789abcdef]*  *L0 * /p" |awk '{print $3}'|while read line
zdb -ddddd $1/ $2 |sed -n "/^  *[0123456789abcdef]*  *L0 * /p" |awk '{print $3":"$4}'|awk -F ':|L' '{print $1":"$2":"$4}'|while read line
do
    #echo "zy:$line"
    zdb -R $1 $line:r >>$3
done

并发模式：

#!/bin/bash
concurrent=100       ## 并发数
echo "readzfsobj.sh <poolname> <objectid> <outfile>"
touch $3
zdb -ddddd $1/ $2 |sed -n "/^  *[0123456789abcdef]*  *L0 * /p" |awk '{print $3":"$4}'|awk -F ':|L' '{print $1":"$2":"$4}' > $2_list
cat $2_list |xargs -P $concurrent -I {} sh -c "zdb -R $1 {}:r > {}"
for line in `cat $2_list`
do 
	cat $line>>$3
	rm -f $line
done
rm -f $2_list
