Posted: Wed Jun 18, 2003 3:23 pm Post subject: help with bash script

I need some help with this script basically im tryin to convert a bunch
of .rm files to mp3 its supposed to take three arguments
a path, first file extention, second file extention. Its supposed to
search all directories under the path and when it finds a file with the
first suffix convert it to mp3 write the mp3 to the same directory the
rm was in in the format file.mp3 I get some weird output when it
actually passed the output file to lame, its saying

Code:

Playing e/nianderson/coast_to_coast/17/COASTREAL20030117_CLIP16.rm
File not found:
'e/nianderson/coast_to_coast/17/COASTREAL20030117_CLIP16.rm'

but the echo shows that it should be working.
any help is greatly appriciated

Code:

#!/bin/bash
ARGS=3
E_BADARGS=65

if [ $# -ne "$ARGS" ]
then
echo "Usage: `basename $0` directory source_extention new_extention"
exit $E_BADARGS
fi
#find all files in directory that match first file type

find $1 -name "*.$2" | while read filename
do echo `dirname $filename``basename $filename $2`$3
done

find $1 -name "*.$2" | while read filename
do mplayer -ao pcm $filename
lame --r3mix audiodump.wav `dirname $filename``basename $filename $2`$3
done

per a suggestion i ran sh -x

here is the output

Code:

sh -x convert2.sh /home/nianderson/coast_to_coast/ rm mp3
+ ARGS=3
+ E_BADARGS=65
+ '[' 3 -ne 3 ']'
+ find /home/nianderson/coast_to_coast/ -name '*.rm'
+ read filename

How about putting a slash between `dirname $filename` and `basename $filename $2`:

Code:

do echo `dirname $filename`/`basename $filename $2`$3

and

Code:

lame --r3mix audiodump.wav `dirname $filename`/`basename $filename $2`$3

i do that and i still have the problem of the /hom disapearing

Code:

find $1 -name "*.$2" | while read filename
do
echo "before mplayer command: $filename"
mplayer -ao pcm $filename
echo "after mplayer before lame: $filename"
lame --r3mix audiodump.wav `dirname $filename``basename $filename $2`$3
echo "after lame: $filename"
done

after more study it actually seems to execute the first loop just fine ... its on the second run of the loop and further where im losing the /hom

any ideas?

I works for me. I created a test dir:

Code:

mkdir tmp/test
touch a.rm b.rm

Then, I created tmp/test.sh:

Code:

find $1 -name "*.$2" | while read filename
do
echo "before mplayer command: $filename"
echo mplayer -ao pcm $filename
echo "after mplayer before lame: $filename"
echo lame --r3mix audiodump.wav `dirname $filename`/`basename $filename $2`$3
echo "after lame: $filename"
done

Running

Code:

sh test.sh /home/thomas/tmp/test rm mp3

gives

Code:

before mplayer command: /home/thomas/tmp/test/a.rm
mplayer -ao pcm /home/thomas/tmp/test/a.rm
after mplayer before lame: /home/thomas/tmp/test/a.rm
lame --r3mix audiodump.wav /home/thomas/tmp/test/a.mp3
after lame: /home/thomas/tmp/test/a.rm
before mplayer command: /home/thomas/tmp/test/b.rm
mplayer -ao pcm /home/thomas/tmp/test/b.rm
after mplayer before lame: /home/thomas/tmp/test/b.rm
lame --r3mix audiodump.wav /home/thomas/tmp/test/b.mp3
after lame: /home/thomas/tmp/test/b.rm

It's all right. Maybe your bash is corrupt...
