I am trying to rename all the files with certain regex patterns within the same subdirectory. Right now, I am in the current directory (above all the sub directories) and am running the following code:
for d in */ ; do
cp $d*hw4*.pl $dhw4.pl
done
I wish to find all the files with hw4 in them, and rename them to hw4.pl and keep them in the same directory. Could someone assist me with this? I know you can do this with the mv command, but I don't want to make a mistake, so I am using copy for now.
Thank you.
I suggest to use find, like this:
find . -type f -name '*hw4*' -execdir mv {} hw4.pl \;

On my Mac I amm trying to move hundreds of files on my NAS drive, from a parent directory with a load of subdirectories (and possibly directories inside them) and put all of the files into one folder.
They don't have the same file extension for all the files.
Is anyone able to help with the terminal command I need to do this? So far I know that find . -type f will list all the files in the directory and subdirectories but Im unsure how to tell it to get them to move them all into another folder.
For anyone else who may have this same issue:
Ive managed to extract just the .jpg's and put them in the parent folder.
find . -type f -iname '*.jpg' -mindepth 2 -print0 | xargs -0 -I{} mv -n '{}' .
Not quite what I wanted - I was hoping to get every single file and put it into a completely different folder if possible but this has got me further than before.
Go inside the source parent directory and use:
find . -type f -exec mv "$PWD"/{} <destination directory> \;
If you want to move all the files to parent directory itself, use it as the destination directory.
I tried the search, but couldn't find the answer to my specific problem.
When I use,
find /recovered_files "*.jpg" -type f -exec cp {} /out \;
to copy all .jpg files from directories within the /recovered_files directory, the /out directory gets filled with every single file (jpg, txt, xml etc etc) from within the source directories.
Can anyone please explain wherein my stupidity lies, pleeeeeease???
Many thanks, Mark.
What you're doing at the moment is equivalent to calling cp /dir/dir/dir/file.jpg /out for each file, which will copy the file into /out. Thus, all of the files are being put into the same directory.
rsync allows filters to select only certain files to be copied. Change from and to to the appropriate directories in the following:
rsync -r from/* to --include=*.jpg --filter='-! */' --prune-empty-dirs
Credit to this post for this solution.
Edit: changed to rsync solution. Original as follows:
find from -name "*.jpg" -type f -exec mkdir -p to/$(dirname {}) \; -exec cp --parents {} to \;
You should replace from and to with the appropriate locations, and this form won't quite work if from begins with /. Just cd to / first if you need to. Also, you'll end up with all the files inside to underneath the entire directory structure of from, but you can just move them back out again.
I have a folder with a number of subfolders. Each of the subfolders consists of several files without extension.
I need to add extension .cel to each file in subfolders.
How can I do it using bash?
find to the rescue:
find /your/folder -type f -exec mv {} {}.cel \;
Explanation: find obtains all files inside the /your/folder structure. From all the results obtained, it performs the mv command. It makes the file XXX to be moved to XXX.cel, which is another way of renaming it.
If you have rename then using that with find should do the trick:
find . -type f -exec rename -v 's/$/\.cel/' {} \;
This should be relatively trivial but I have been trying for some time without much luck.
I have a directory, with many sub-directories, each with their own structure and files.
I am looking to find all .java files within any directory under the working directory, and rename them to a particular name.
For example, I would like to name all of the java files test.java.
If the directory structure is a follows:
./files/abc/src/abc.java
./files/eee/src/foo.java
./files/roo/src/jam.java
I want to simply rename to:
./files/abc/src/test.java
./files/eee/src/test.java
./files/roo/src/test.java
Part of my problem is that the paths may have spaces in them.
I don't need to worry about renaming classes or anything inside the files, just the file names in place.
If there is more than one .java file in a directory, I don't mind if it is overwritten, or a prompt is given, to choose what to do (either is OK, it is unlikely that there are more than one in each directory.
What I have tried:
I have looked into mv and find; but, when I pipe them together, I seem to be doing it wrong. I want to make sure to keep the files in their current location and rename, and not move.
The GNU version of find has an -execdir action which changes directory to wherever the file is.
find . -name '*.java' -execdir mv {} test.java \;
If your version of find doesn't support -execdir then you can get the job done with:
find . -name '*.java' -exec bash -c 'mv "$1" "${1%/*}"/test.java' -- {} \;
If your find command (like mine) doesn't support -execdir, try the following:
find . -name "*.java" -exec bash -c 'mv "{}" "$(dirname "{}")"/test.java' \;
I am horrible at writing bash scripts, but I'm wondering if it's possible to recursively loop through a directory and rename all the files in there by "1.png", "2.png", etc, but I need it to restart at one for every new folder it enters. Here's script that works but only does it for one directory.
cd ./directory
cnt=1
for fname in *
do
mv $fname ${cnt}.png
cnt=$(( $cnt + 1 ))
done
Thanks in advance
EDIT
Can anyone actually write this code out? I have no idea how to write bash, and it's very confusing to me
Using find is a great idea. You can use find with the next syntax to find all directories inside your directory and apply your script to found directories:
find /directory -type d -exec youscript.sh {} \;
-type d parameter means you want to find only directories
-exec youscript.sh {} \; starts your script for every found directory and pass it this directory name as a parameter
Use find(1) to get a list of files, and then do whatever you like with that list.
