dd 命令实时进度监控

dd脚本：

#!/bin/sh
if [ -d "${1}" ]; then
echo "!mkdir"
else
mkdir ${1}
fi

cd ${1}
name=`date +%Y%m%d_%H%M%S`
dd if=/dev/cdrom of=${1}${name}.iso && md5sum ${1}${name}.iso >> md5sum.txt

监控脚本：“cut -b 4-14”中数字与用户名字有关。

#!/bin/sh
pid=`ps -ef | grep "dd if=/dev/cdrom of=" | cut -b 4-14 | sed -n '1p'`
watch -n 1 kill -USR1 ${pid}
