How to backup DVD?

四常用「Brasero」抑是「K3b」，無，用「dvd::rip」。

欲較簡單的，就用「readom」、「wodim」。

（1）wodim --devices

列出會當用的設備。親像：

-------------------------------------------------------------------------
0 dev='/dev/scd0' rwrw-- : 'Slimtype' 'DVD A DS8A4SH'
-------------------------------------------------------------------------

（2）readom dev=/dev/scd0 f=dvd.iso

共dvd 備份做ISO檔案。

「dev=設備名」。

「f=ISO檔名」。

（3）wodim -v dev=/dev/scd0 -eject dvd.iso

共ISO檔案燒做dvd來備份。

「-v」：verbose，顯示進度。

「-eject」：燒好共dvd退出來。

How to remove mp3 tags?

一堆以早備份的mp3檔案，內底的標籤（tag）攏是亂碼（BIG5？），MP3 player無法度正確顯示。貧惰閣去處理，直接用「id3v2」共標籤提掉較緊。



find . -name "*.mp3" -exec id3v2 -D '{}' ';'

「-D」會共「id3v1」、「id3v2」的標籤攏提掉。

「'{}'」表示「find」揣著的檔案。

How to convert mp3 to ogg?

有1堆「mp3」的歌曲，想欲轉做開放的「ogg」格式，直接用「ffmpeg」就會當。



for i in *.mp3; do ffmpeg -sameq -i "$i" "${i%.*}.ogg"; done

「${i%.*} 」是Shell的功能，會共「extension name」（.mp3）提掉。

有寡player干焦會當放mp3，按呢無法度，著愛共ogg 轉做 mp3：

for i in *.ogg; do ffmpeg -sameq -i "$i" "${i%.*}.mp3"; done

How to convert multiple characters at a time?

共2、3个字元做一擺換掉？親像共

2012-01-21 10:59

換做

2012_01_21_11_07

（1）上簡單的做法就是用「tr」，可比

date +'%F %R' | tr '\-: ' '_'

（2）嘛會當用「sed」，可比

date +'%F %R' | sed -r 's/-| |:/_/g'

注意：「sed」欲用「|」（or），愛加「-r」，使用擴充的「regular expression」語法。

（3）較簡單的情形免用「|」，直接用「character class」（character set）就會當，可比

date +'%F %R' | sed 's/[- :]/_/g'
