I am using the following command to find files, zip them up and delete the original file:
find data/* -type f -execdir zip '{}'.zip '{}' \; -delete
At the moment if a file called "something.txt" is found a zip file called "something.txt.zip" is created. How do I make the filename "something.zip" instead?
I know in bash I can do something like ${x:.*} but I cannot seem to get something like this working here.
This seems to work but it is a bit of a fudge:
find data/* -execdir bash -c 'zip -j "${1%.*}.zip" "${1}"' _ {} \;
I would love to see something cleaner.

I have a bash script I cannot get working. I am a dead set beginner in bash this is actually the first script I've ever used. I'm trying to get omxplayer to play a list of files in a directory. When the script runs I get feedback showing the file then the error that there is no such file or directory. Please help me?
#!/bin/sh
find /media/pi/88DC-E668/MP3/ -name "*.mp3" -exec PLAY={} \;; omxplayer "$PLAY";
This is the echo:
find: `PLAY=/media/pi/88DC-E668/MP3/Dance.mp3': No such file or directory
find: `PLAY=/media/pi/88DC-E668/MP3/Whitemary.mp3': No such file or directory
find: `PLAY=/media/pi/88DC-E668/MP3/Limo.mp3': No such file or directory
find: `PLAY=/media/pi/88DC-E668/MP3/Silo.mp3': No such file or directory
File "" not found.
Easy way:
find /media/pi/88DC-E668/MP3 -name \*.mp3 -exec omxplayer {} \;
or
while IFS= read -r -d '' mp3
do
omxplayer "$mp3"
done < <(find /media/pi/88DC-E668/MP3 -name \*.mp3 -print0)
or
find /media/pi/88DC-E668/MP3 -name \*.mp3 -print0 | xargs -0 -n1 omxplayer
You can omit the -n1 if the omxplayer could handle multiple filenames. In such case the 1st could be written as:
find /media/pi/88DC-E668/MP3 -name \*.mp3 -exec omxplayer {} +
but the simplest probably will be
#shopt -s globstar #the default is on
for mp3 in /media/pi/88DC-E668/MP3/{,**/}*.mp3
do
omxplayer "$mp3"
done
EDIT I stand corrected, but won't delete the answer as you can also learn from the mistakes of others. See comment and rather use this answer :)
So please don't do it like this, as this is a typical "happy path" solution - meaning: it works if you know what you're doing and you know your paths (e.g. that they don't contain spaces). I keep forgetting that many people don't know yet that spaces in paths are evil.
Just use xargs to pass what you found to your player like this:
#!/bin/sh
find /media/pi/88DC-E668/MP3/ -name "*.mp3" | xargs omxplayer
The -exec foo part means run the command foo for each path found.
In your case, -exec PATH={}, the {} part is replaced with the path name, ending up with something like -exec PATH=/media/pi/88DC-E668/MP3/Dance.mp3, and so then find tries to run the command PATH=/media/pi/88DC-E668/MP3/Dance.mp3 which fails because there isn't actually any such program to execute.
xargs is the usual way to do what you're trying to do, as described in another comment already.
You could also do:
find /media/pi/88DC-E668/MP3/ -name \*.mp3 |
while read f; do
omxplayer "$f"
done
I have a directory with many subdirectories and files with suffixes in those subdirectories (e.g FileA-suffixA FileB-SuffixB FileC-SuffixC FileD-SuffixA, etc).
How can I recursively search for files with a certain suffix, and append a user-defined line of text to those files? I feel like this is a job for grep and sed, but I'm not sure how I would go about doing it. I'm fairly new to scripting, so please bear with me.
You can do it like
find /where/to/search -type f -iname '*.SUFFIX' -exec echo "USER DEFINED STRING" >> \{\} \;
find searches in the suplied path
-type f finds only files
-iname '*.SUFFIX' find the .SUFFIXed names, case ignored
find ./ -name "*suffix" -exec bash -c 'echo "line_to_add" >> $1' -- {} \;
Basically you use find to get a list of the files. Then you use bash to echo append your line to that list.
I have the following script that finds any file with the .mp3 extension in the incoming directory and moves it to the complete directory - it works perfectly!
#!/bin/bash
find /usr/audio/incoming -name '*.mp3' -exec mv {} /usr/audio/complete \;
exit
Now, I've installed eyeD3 (http://eyed3.nicfit.net/index.html) and I'm attempting to rename the Title tag somewhere during this entire process before it gets moved to the complete directory.
I've tried the following (and many more) but none of them work at all:
Trying to do it all in the same line...
#!/bin/bash
find /usr/audio/incoming -name '*.mp3' eyeD3 -t "New Title" -exec mv {} /usr/audio/complete \;
exit
Trying to do it by splitting it up...
#!/bin/bash
cd /usr/audio/incoming eyeD3 -t "New Title" '*.mp3';
find /usr/audio/incoming -name '*.mp3' -exec mv {} /usr/audio/complete \;
exit
Even just trying to get eyeD3 to rename the tag and nothing else...
#!/bin/bash
cd /usr/audio/incoming eyeD3 -t "New Title" '*.mp3';
exit
I know that i'm doing something wrong, but I've searched high and low and there is virtually zero newbie support for eyeD3 that I can find. What there is out there tends to be for python scripts that don't really do what I need anyway.
Does anybody know where I'm going wrong here?
For clarity, I want to rename the tag of every single mp3 file in this directory with the same title, but all of the mp3s have different file names, which is why I'm using the wildcard instead of the file name. Maybe I'm doing this the wrong way?
I think this will work:
find /usr/audio/incoming -name '*.mp3' -exec eyeD3 -t 'New Title' '{}' \; -exec mv '{}' /usr/audio/complete \;
I'm trying to come up with a command that would run mp3gain FOLDER/SUBFOLDER/*.mp3 in each subfolder, but I'm having trouble understanding why this command doesn't work:
find . -type d -exec mp3gain \"{}\"/*.mp3 \;
When run, I get error Can't open "./FOLDER/SUBFOLDER"/*.mp3 for reading for each folder and subfolder.
If I run command manually with mp3gain "./FOLDER/SUBFOLDER"/*.mp3 it works. What's going wrong?
If you have a fixed data structure like
folder1/subfolder1/
folder1/subfolder2/
folder2/subfolder1/
[...]
and using zsh or bash version >=4.0 you could try
mp3gain **/*.mp3
But to make sure check the output of
ls **/*.mp3
before you are getting serious with mp3gain.
When you run mp3gain "./FOLDER/SUBFOLDER"/*.mp3 from your shell, the *.mp3 is getting expanded by the shell before being passed to mp3gain. When find runs it, there is no shell involved, and the *.mp3 is getting passed literally to mp3gain. The latter has no idea how to deal with wildcards (because normally it doesn't have to).
Hmmm. Just tried this to test how the directory is parsed by replacing mp3gain with echo and it works:
find . -type d -exec echo {}\/\*.mp3 \;
Try running your version of the command but with echo to see the file output for yourself:
find . -type d -exec echo \"{}\"/*.mp3 \;
Seems the quotes get in the way in your original command.
this works...
find /music -name *mp3 -exec mp3gain -r -k {} \;
I have a bunch of zip files, and I'm trying to make a bash script to automate the unzipping of certain files from it.
Things is, although I know the name of the file I want, I don't know the name of the folder it's in; it is one folder depth in
How can I extract these files, preferably discarding the folder?
Here's how to unzip any given file at any depth and junk the folder paths on the way out:
unzip -j somezip.zip *somefile.txt
The -j junks any folder structure in the zip file and the asterisk gives a wildcard to match along any path.
if you're in:
some_directory/
and the zip files are in any number of subdirectories, say:
some_directory/foo
find ./ -name myfile.zip -exec unzip {} -d /directory \;
Edit: As for the second part, removing the directory that contained the zip file I assume?
find ./ -name myfile.zip -exec unzip {} -d /directory \; -exec echo rm -rf `dirname {}` \;
Notice the "echo." That's a sanity check. I always echo first when executing something destructive like rm -rf in a loop/iterative sequence like this. Good luck!
Have you tried unzip somefile.zip "*/blah.txt"?
You can use find to find the file that you need to unzip, and xargs to call unzip:
find /path/to/root/ -name 'zipname.zip' -print0 | xargs -0 unzip
print0 enables the command to work with files or paths that have white space in them. -0 is the option to xargs that makes it work with print0.
