Bash Script outputs to text file But it's not in alphabetical order?

[Singtoh]

Hello All,

I have been trying to get this script to work properly and I have nearly given up. That is why I thought I would post here for some help. This is not my script, I found it on the internet and have tried to adapt it to my needs but am not having to much luck. I know there is some extra stuff in the script that I don't need but it runs sort of? I am not a scripter or coder by any means, getting a bit too old for that I think. The script runs but what I would like it to do is output to a text file in my home directory. It outputs now but the results are not in alphabetical order and I would like all the Artists to be printed from A-Z if this is possible. This script is going to scan my music library and retrieve the replaygain data from all of the flac tags. The reason I am trying to do this is because I am trying to use replay gain values to pick out tracks that are possibly clipped so I don't have to open every single file in audacity one by one. I have had about %60-%70 percent in being able to pick files that have some clipping on them. Unless someone has a better idea or a better way. I have around 700gig of flac files to check, so this will take awhile. Anyway here is the script and I hope someone can help sort this mess out. I thank all of you for any kind help in advance, I really appreciate it.


Cheers,

could you post a little bit of the output your currently getting?

The directory part /media/Storage/Music/Rock/ I don't need but couldn't seem to make it go away without making it log nothing??

So if I could get the Artist into alphabetical order for a start would be nice or another idea I had would be to highlight all the numbers of REPLAYGAIN_TRACK_GAIN=-9.58 dB and REPLAYGAIN_ALBUM_GAIN=-9.58 dB to BOLD and RED all the way tru that go below say -4dB then I really wouldn't need to order it from A-Z. That would give me a visual cue of something to look at, then I could adjust that -4dB number to what works best for finding the clipped tracks, or even just have it log to a file anything that goes below -4dB according to REPLAYGAIN_TRACK_GAIN=-9.58 dB and REPLAYGAIN_ALBUM_GAIN=-9.58 dB or a given number, I don't know of the best way?? I ran this thru my library and its like 3000 pages long. I wish there was a program that say would open the flac files one by one, find clipping, close said track, log it to a file and then carry on all the way thru but I think that's a pipe dream?? Do you have any ideas possibly?? I guess it's a start if I can get it in order and/or highlighted in some way?? I just can't get my head around this scripting stuff. Thanks SlugSlug for the reply and hopefully some help

Hello All,

This is what i have now which outputs to the text file better but it only prints the last bit of the file??

#!/bin/bash -u
echo "You entered: '${*-}'"

(
if [ ! -d "$1" ]
then
    echo "Arg "$1" is NOT a directory!"
    exit $ARGUMENT_NOT_DIRECTORY
fi

flacnum=`ls "$1" | grep -c \\.flac`

if [ $flacnum -lt 1 ]
then
    echo $1" (No FLAC files, moving on)"
    exit 0
else
    echo $1" ("$flacnum" FLAC files)"
fi

    echo "Tag Values Retrieved:"
flacfiles=`ls -1 "$1"/*.flac`
IFS=$'\012'
for file in $flacfiles
do
    if [ ! -e "$file" ]
    then
    echo "Error: file "$file" not found."
    exit $FILE_NOT_FOUND
    fi


    metaflac --show-tag=ARTIST --show-tag=TITLE --show-tag=REPLAYGAIN_TRACK_GAIN --show-tag=REPLAYGAIN_ALBUM_GAIN --show-tag=REPLAYGAIN_ALBUM_PEAK "$file"

    
done) 2>&1 | tee rgainvaluesMUSIC.log

And here is what is in the text file after I ctrl+c to stop it after a minute or so, it's just the last bit of info from rite before I hit ctrl+c???:

title=Time for Me to Fly
REPLAYGAIN_TRACK_GAIN=-7.49 dB
REPLAYGAIN_ALBUM_GAIN=-8.52 dB

As I said, I am not a coder by any stretch,not even a little bit, just trying get something that works somewhat??

I haven't really read your script, but try

tee -a rgainvaluesMUSIC.log

(a = append - the default for tee is to overwrite)

[Vaphell]

to print out track/album gains below -4

awk -v threshold=-4 '
      /[/]media[/]/ { file=$0 }
      /TRACK_GAIN/ { t_gain=$1; sub( /.*=/, "", t_gain ); }
      /ALBUM_GAIN/ { a_gain=$1; sub( /.*=/, "", a_gain ); }
      /ALBUM_PEAK/ { if (t_gain < threshold || a_gain < threshold) print file "\ntrack gain: " t_gain ", album gain: " a_gain; }
    ' in.txt

i can only guess what you meant exactly though, your description of the problem is rather chaotic

Thanks Steeldriver. That let it print all 3000 pages of info. Now if I can narrow it down some I might win. I appreciate the help.

read post #6
below -4.0 as in -5, -6... -9, etc?

Sorry for the chaotic explanation Maybe I can be more clear. I am trying to scan the whole music library of around 700gig of flac files with this replaygain script and pick out high replaygain values, high meaning below -4dB(or I could change that number to what works best for finding clipping). So for instance a replaygain value of -10dB is most likely to have clipping on that track, and a replaygain value of -4dB is most likely to be clean. Then I can go to Audacity and fix it or if it's too bad, throw it out and re-rip the album. So if it prints only what is below i.e -4dB, I might only have to look at 2000 files instead of 8000. I don't know of another way to do this, but I think it's going to be a job to say the least I hope that is a bit more clearly put. I thank you very much Vaphell and Steeldriver for the help, I really appreciate it. I don't think I could ever wrap my head around this coding, it's giving me a headache

Cheers,

Singtoh

hm, works here on the test file... maybe try changing the pattern to this one in blue

$ awk -v threshold=-4 '
