讓 /bin/dd 有進度 (dd with progress Ubuntu/Fedora)
有兩種方式達成:
1. 配合 "pv" 或 "pv -s SIZE" 使用
代碼:
$ apt-get install pv (or, yum install pv)
$ dd if=/dev/zero bs=4096 | pv -s 2G | of=/tmp/file
(這裡的 -s 2G 取代 count=524288)
2. 或者直接安裝 "dcfldd" 配合 "time"
代碼:
$ apt-get install dcfldd (or, yum install dcfldd)
$ man dcfldd
$ dcfldd if=/dev/zero bs=4096 of=/tmp/file count=524288 statusinterval=1
$ time dcfldd if=/dev/zero bs=4096 of=/tmp/file count=524288 statusinterval=1
