I've run a batch process to resize and optimize all images within a directory and subdirectories. Unfortunately, Photoshop CC doesn't have an option (that I'm aware of) to overwrite the existing images and instead creates a 'JPEG' directory anywhere it processes images and writes the processed images there. The number of images is relatively large (~2000 images) and they're divided into hundreds of subdirectories, so manually moving the images to overwrites the existing ones is out of the question.
How can I move all of the processed images in the 'JPEG' directories up a level to overwrite the original images? The closes I think I've come is this:
find . -type d -name "JPEG" -exec cd {} \; && find . -type f -name "*.jpg" -exec mv -v {} .. \;
...but that drops all the images a level up from my current directory.
Can some one sort me out?
Your cd only affects a subprocess which changes to the directory and dies, while its parent process remains unaffected.
Anyway, switching to a directory is rarely necessary or useful; just use the path directly in the mv command.
find . -type d -name "JPEG" -exec mv -v {}/*.jpg {}/.. \;
(Not in a place where I can test right now, but I guess the wildcard needs a shell, too:
find . -type d -name "JPEG" -exec sh -c 'mv -v {}/*.jpg {}/..' \;
Untested, obviously.)
backup your image directory before using the following script.
CURRENT_DIR=$(pwd)
for x in $(find -type d -name 'JPEG')
do
cd $x && mv -v *.jpg .. # you can use `cp` instead of `mv`, then remove JPEG directory.
cd $CURRENT_DIR
done

I want to write a shell script to do the following :
I have a folder with many subfolders. Each of these subfolders has a *.gz file and some other files which I don't need. I want to move all .gz files into a new subfolder called needed_files (I have already created this subfolder). So I did the following :
I went to the parent folder with all the subfolder and cp /.gz > needed_files/., but this did not work. Can you suggest what I should be doing?
grep is irrelevant here. Use find:
find . ! \( -type d -name needed_files -prune \) -type f -name '*.gz' \
-exec echo mv -t needed_files {} +
POSIX equivalent of that -exec is
-exec sh -c 'echo mv "$#" needed_files' _ {} +
If its output looks good, remove echo.
Btw I noticed that the title says copy but you also say I want to move, so decide on what you exactly want to do and let me know so I can edit my answer.
I have a folder with tens of thousands of different file types. Id like to copy them all to a new folder (Copy1) but also rename them all to $RANDOM but keep the extension intact. I realize I can write a line specifying which extension to find and how to name it, but there is got to be a way to do it dynamically, because there are at least 100 file types and may be more in the future.
I have the following so far:
find ./ -name '*.*' -type f -exec bash -c 'cp "$1" "${1/\/123_//_$RANDOM}"' -- {} \;
but that puts the random number after the extension, and also it puts the all in the same folder. I cant figure out how to do the following 2 things:
1 - Keep all paths intact, but in a new root folder (Copy1)
2 - How to have name be $RANDOM.extension, instead of .extension.$RANDOM
PS - by $RANDOM i mean actual randomly generated number. I am interested in keeping folder structure, so we are dealing with a few hundred files at most per directory, but all directories/files need to be renamed to $RANDOM. Another way to look at what I need to do. Copy all contents or Folder1 with all subdirectories and files to Folder2 (where Fodler2 is a $RANDOM name), then rename all folders and files to random names but keep all extensions.
EDIT: Ok i figured out how to rename and keep extension. But I have a problem where its dumping all of the files into the root directory where script is run from. How do I keep them in their respective folders? Command Im using is:
find ./ -name '*.*' -type f -exec bash -c 'mv "$1" $RANDOM.${1##*.}' -- {} \;
Thanks!

Change your command to:
PATH=/bin:/usr/bin find . -name '*.*' -type f -execdir bash -c 'mv "$1" $RANDOM.${1##*.}' -- {} \;
Or alternatively using uuids instead of random numbers:
PATH=/bin:/usr/bin find . -name '*.*' -type f -execdir bash -c 'mv "$1" $(uuidgen).${1##*.}' -- {} \;
Here's what I came up with :
i=1
random="whatever"
find . -name "*.*" -type f | while read f
do
newbase=${f/*./$random$i.} //added counter to filename
cp $f /Path/Name/"$newbase"
((i++))
done
I had to add a counter to random (i), otherwise, if the extensions are similar, your files would overwrite themselves when copied.
In your new folder, your files should look like this :
whatever1.txt
whatever2.txt
etc etc
I hope this is what you were looking for.
Here is the command that worked for me.
find . -name '*.pdf' -type f -exec bash -c 'echo "{}" && cp "$1" ./$RANDOM.${1##*.}' -- {} \;
I currently have ~40k RAW images that are in a nested directory structure. (Some folders have as many as 100 subfolders filled with files.) I would like to move them all into one master directory, with no subfolders. How could this be accomplished using mv? I know the -r switch will copy recursively, but this copies folders as well, and I do not wish to have subdirectories in the master folder.
If your photos are in /path/to/photos/ and its subdirectories, and you want to move then in /path/to/master/, and you want to select them by extension .jpg, .JPG, .png, .PNG, etc.:
find /path/to/photos \( -iname '*.jpg' -o -iname '*.png' \) -type f -exec mv -nv -t '/path/to/master' -- {} +
If you don't want to filter by extension, and just move everything (i.e., all the files):
find /path/to/photos -type f -exec mv -nv -t '/path/to/master' -- {} +
The -n option so as to not overwrite existing files (optional if you don't care) and -v option so that mv shows what it's doing (very optional).
The -t option to mv is to specify the target directory, so that we can stack all the files to be moved at the end of the command (see the + delimiter of -exec). If your mv doesn't support -t:
find /path/to/photos \( -iname '*.jpg' -o -iname '*.png' \) -type f -exec mv -nv -- {} '/path/to/master' \;
but this will be less efficient, as one instance of mv will be created for each file.
Btw, this moves the files, it doesn't copy them.
Remarks.
The directory /path/to/master must already exist (it will not be created by this command).
Make sure the directory /path/to/master is not in /path/to/photos. It would make the thing awkward!
Make use of -execdir option of find:
find /path/of/images -type f -execdir mv '{}' /master-dir \;
As per man find:
-execdir utility [argument ...] ;
The -execdir primary is identical to the -exec primary with the exception that
utility will be executed from the directory that holds the current
file. The filename substituted for the string ``{}'' is not qualified.
Since -execdir makes find execute given command from each directory therefore only base filename is moved without any parent path of the file.
find <base location of files> -type -f -name \*\.raw -exec mv {} master \;
If your hierachy is only one level deep, here is another way using the automated tools of StringSolver:
mv -a firstfolder/firstfile.raw firstfile.raw
The -a options immediately applies the similar transformation to all similar files at a nesting level 1 (i.e. for all other subfolders).
If you do not trust the system, you can use other options such as -e to explain the transformation or -t to test it on all files.
DISCLAIMER: I am a co-author of this work for academic purposes, and working on a bash script renderer. But the system is already available for testing purposes.
I want to copy just the files i've created/edited today into a separate directory "changeset" whilst maintaining their directory structure
I came up with the following script
cd ./myproject/
find ./* -mtime -1 -daystart -exec cp {} ../changeset/{} \;
The drawbacks of the above is that directories aren't created and the copy throws an error.
I've manually gone into ../changeset/ and create the folder structure until the command runs without errors.. but thats a little tedious.
Is there a simple solution to this?
find * -mtime -1 -daystart -print0 | cpio -pd0 ../changeset
cpio is an old, oddball archival program that is occasionally the best tool for the job. With -p it copies files named on stdin to another directory. With -d it creates directories as needed.
I've found another solution which isn't as elegant as John's but which isn't reliant on cpio, which i dont have.
cd ./myproject/
# Create all directories
find ./* -type d -exec mkdir ../changeset/{} \;
# Copy files
find ./* -mtime -1 -daystart -exec cp {} ../changeset/{} \;
# Delete empty directories, run this several times because after moving a child the parent directory needs to be removed
find ../changeset/ -type d -empty -exec rmdir {} \;
I have some folder hierarchy, in some of the folders there are images, I need a shell script which can list all images and copy them into one specified folder, where listing them is not important, I just want to copy all images into a folder?
I know I can
ls -R *.png
but how do I copy them all to one folder?
Thanks!
Update: As glenn jackman has pointed out, this would be slightly more efficient to use over the answer I provided:
file . -type f -name \*.png | xargs cp -t destination
For the explanation, see glenn's comments that follow this answer.
One way is to use find:
find . -type f -name "*.png" -exec cp {} ~/path/to/your/destination/folder \;
Explanation:
find is used to find files / directories
. start finding from the current working directory (alternatively, you can specify a path)
-type f: only consider files (as opposed to directories)
-name "*.png": only consider those with png extension
-exec: for each such result found, do something (see below)
cp {} ~/path/to/your/destination/folder \;: this is the do something part: copy each such result found (substituted into the {}) to the destination specified.
To copy multiple file patterns in single go we can use -regex instead -name
find . -type f -regex '.*\(jpg\|jpeg\|png\|gif\|mp4\|avi\|svg\|mp3\|vob\)' -exec cp {} /path/to/your/destination/folder \;
