I am trying to write a shell script that covert all the music file in a folder to use the following format. Tract 01.wav....... Would the following script work?
makedir /music_ram
mount -t tmpfs -o -size=800m none /music_ram
mv "01*.wav" /music_ram/Track 01.wav
mv "02*.wav" /music_ram/Track 02.wav
mv "03*.wav" /music_ram/Track 03.wav
mv "04*.wav" /music_ram/Track 04.wav
mv "05*.wav" /music_ram/Track 05.wav
mv "06*.wav" /music_ram/Track 06.wav
mv "07*.wav" /music_ram/Track 07.wav
mv "08*.wav" /music_ram/Track 08.wav
mv "09*.wav" /music_ram/Track 09.wav
mv "10*.wav" /music_ram/Track 10.wav
mv "11*.wav" /music_ram/Track 11.wav
mv "12*.wav" /music_ram/Track 12.wav
mv "13*.wav" /music_ram/Track 13.wav
mv "14*.wav" /music_ram/Track 14.wav
mv "15*.wav" /music_ram/Track 15.wav
mv "16*.wav" /music_ram/Track 16.wav
mv "17*.wav" /music_ram/Track 17.wav
mv "18*.wav" /music_ram/Track 18.wav
mv "19*.wav" /music_ram/Track 19.wav
mv "20*.wav" /music_ram/Track 20.wav

1. makedir? mkdir?
2. Why create directory under / (root) directory?
3. You may want to cd (change directory) to the directory where *.WAV are placed...
I don't know what does it mean by mounting none to a directory, so I leave it to other members...

why not try it by using "cp" instead of "mv"?

我諗有 D 小問題令你個 script 未必 work 喎
首先有版友講o左 makedir 應該係 mkdir
跟住句 mount command 個 -o -size=800m 應該係 -o size=800m
然後就係 D mv commands, 你係想 move "Track 01.wav", "Track 02.wav" 等等入去個 directory 入面? 你句 mv command 個 source 寫 "01*.wav", 咁應該唔會 match 到用 Track 開頭o既 file 名
其實如果你想將全部 Track 開頭o既 files move 晒去o個個 directory, 你用一句mv Track*.wav /music_ram/
就 OK
最後都係提一句, 你 move 落去個 directory reboot 完就會 clear o左, 你 move 之前最好先 make sure D file 係用完就洗得

個script初頭最好有個if. 假如個directory唔係度先再mkdir.

Do you know the different of "01*.wav" ( double quotation mark ) and 01*.wav ( no quotation mark ) ??

It could be a little bit better, but I can't see a big difference in terms of performance or neatness.
"mkdir" itself will check on its own, right ??

You don't want any unnecessary message in the sysout (or redirected logfile).
mkdir: cannot create directory `test': File exists

Wow, 你唔講我都冇為意添
返而後面個 "Track 01.wav" 應該要 quote 
Filename expansion 係容易搞亂, 舉個例, 一個 Folder 入面有三個 File 我當叫 file01.txt, file02.txt, file03.txt:
1) ls -l file*.txt
2) ls -l "file*.txt"
3) for i in "file*.txt"; do ls -l $i; done
邊個 list 到邊個又 list 唔到 ?

I agree it is a good practice, but I don't agree it is an important step to solve the current issue.

Case 1 & 2 is quite obvious, but case 3 may be shell dependent.

It is quite interesting that the "file*.txt" in case 2 doesn't get expanded when being passed to ls so it won't match any file, while the "file*.txt" in case 3 will get expanded to a list properly by bash before loop thus giving correct output.作者: ackcheng 時間: 2009-1-3 01:43
Thankyou so much for everyones help
I actually wants to replace all music files with
01. Happy song.wav
02. Said song.wav....
to
Track 01.wav
Track 02.wav
Here is the revised script
mkdir /music_ram
mount -t tmpfs -o size=800m none /music_ram
mv "01*.wav" /music_ram/"Track 01.wav"
mv "02*.wav" /music_ram/"Track 02.wav"
mv "03*.wav" /music_ram/"Track 03.wav"
mv "04*.wav" /music_ram/"Track 04.wav"
Looks OK?

You are still missing from the difference of "01*.wav" and 01*.wav ( simply double quoted and non double quoted )
If you are not very good at handling wildcard, why not use a text editor to help it ?
For example,
Write cp -v "01. love song.wav" "Track 01.wav" instead. ??
Here is my implement of your script.
n=1
for i in *.wav
do
f=`printf "Track %02d.wav" $n`
cp -v $i outdir/"$f"
n=$((n+1))
done

Thanks.
I need some time to digest your code.
