[SOLVED] Can Diff take arrays as input?

NirvanaII · 06-21-2010, 05:50 PM

Code:

path[x]=$(dirname "$(awk NR==$x Musiclist.txt)")

dirname did the job!

Thanks for the assistance grail and smeezekitty!

(i'll mark as SOLVED now, but if you wanna make any suggestions to improve the command go ahead.)

Well I am kind of curious why the 6 mile long test in the while loop??

I am still reading through it all and will have a suggestion shortly

Ok ... so this is untested but seems ok:

Code:

#!/bin/bash

while read line
do
	mfile=$(echo "${line##*/}")
	wfile=$(echo "${mfile%%mp3}wav")
	ffile=$(echo "${mfile%%mp3}flac")
	
	ln -s "$line" "$mfile"
	
	mplayer -cache 32 -ao pcm:file="$wfile" "$mfile"
	lame -V2 "$wfile" "$ffile"
	
	rm -vf *.wav *.mp3
	mv -v "$ffile" $(dirname "$line")
done< <(find "$My_Music" -iname "*.mp3")

Code:

stuart@stuart:~/music transfer$ ./grail\'s\ script.sh 
./grail's script.sh: line 7: unexpected EOF while looking for matching `)'
./grail's script.sh: line 17: syntax error: unexpected end of file
stuart@stuart:~/music transfer$ cat grail\'s\ script.sh 
#!/bin/bash

while read line
do
	mfile=$(echo "${line##*/}")
	wfile=$(echo "${mfile%%mp3}wav"
	ffile=$(echo "${mfile%%mp3}flac"
	
	ln -s "$line" "$mfile"
	
	mplayer -cache 32 -ao pcm:file="$wfile" "$mfile"
	lame -V2 "$wfile" "$ffile"
	
	rm -vf *.wav *.mp3
	mv -v "$ffile" $(dirname "$line")
done< <(find "$My_Music" -iname "*.mp3")
stuart@stuart:~/music transfer$

???

The mile long test to read it, or the literal test?

And looping is all I know, right now.

So... where does the input come from initially here? I can only partially tell as to what's going on. The bit i'd expect first is the last line. Very curious.

(I have quite literally just read a few 'bits' out a loaned library book, and thought i'd make a rough program while dipping in and out of it. My knowledge is scant or rudimentary... whichever the more polite

)

Man I am sorry about that, wrote it on the fly and didn't check my closing brackets

I have edited above so if you copy it again it should work (well at least run)

Yeah good question. This considered a here document reference which simply put will return each file from the find and work on each one.

I use the following link as a reference, and as long as you have a little time it can be used by new users too (as it is called Advanced)

tldp.org/LDP/abs/html/

I'll take a look through that page when the book is returned.

I hate to say it, but...

Code:

stuart@stuart:~/music transfer$ echo $My_Music
/mnt/sda1/Music/
stuart@stuart:~/music transfer$ ./grail\'s\ script.sh 
find: cannot search `': No such file or directory

The env var works fine:

Code:

stuart@stuart:~/music transfer$ find "$My_Music" -iname "*.mp3" | awk NR==1
/mnt/sda1/Music/Belly/06 - The Bees.mp3

hmmm ... well you have me a little stumped then???

I just ran the same on my machine after creating the environment variable and changing script to just echo found files and it all worked swimmingly??

Maybe you could comment out the rest and just put an echo of your variable in the script to see if it is seeing it?
