I have a directory with about 5,000 subdirectories in it.
Each subdirectory contains one file each.
I'd like to collect those files and put them in the same folder somewhere.
Is there a way to do that by Mac OSX terminal command? Or should I write a, say, python script to do that?
Something like,
find . -type f -exec echo mv {} /path/to/dst/dir/ \;
You'll have to tweak this according to your circumstances, of course. See man find for details. Remove the echo when you're ready to run for real (preferably after taking a backup).

I have following directory structure :
/home/dir1/abc.jpg
/home/dir1/abc.pdf
/home/dir1/dir2/abc.jpg
/home/dir1/dir2/abc1.jpg
/home/dir1/dir2/dir3/abc.jpg
and I want to copy jpg files from them to a new folder which will have same directory structure, for eg.:
/home/newdir1/abc.jpg
/home/newdir1/dir2/abc.jpg
/home/newdir1/dir2/abc1.jpg
/home/newdir1/dir2/dir3/abc.jpg
How to achieve it using rsync or any other software ?
Please help, Many Thanks !!
From the looks of what you've included in your question, there are a couple of things you might try.
You've specified that you want to "move" files. That means you either use the mv command, or use rsync's --remove-source-files option. For example:
mv /source1/* /source2/* /path/to/targetdir/
or
rsync -a /source1/ /source2/ /path/to/targetdir/
You've no doubt already read the part of rsync's man page that explains the difference between source dirs with and without their trailing slash. If not, read up, because it's important.
If your "thousands of source files [with] similar names" need to be matched from within your source directories, leaving some other files behind, you need to determine whether your "similar names" can be differentiated using pathname expansion or if you should use a regular expression. If the former, then adding the pathname expansion to your sources with either mv or rsync should be sufficient. If you need to use a regex, then find may be a better option:
find /source1/ /source2/ -regex ".*/file[A-F][0-9][0-9].txt" -exec mv "{}" /targetdir/ \;
If these don't solve the problem, then you'll need to supply more detail in your question.
I would try a little shell script like this:
#!/bin/sh
cd /home/dir1
JPEGS=`find . -name "*.jpg"`
tar cf - $JPEGS | (cd /home/newdir1 ; tar xf -)
This first gets the list of all your jpg files with their relative paths, then writes a tar file of them to a pipe into a subshell which changes to the new directory, and then extracts the tar from its stdin.
I thought this would be more of a one liner to be honest.
Pretty simple in notion:
using find on Mac OS X, locate files that meet a criteria, in my case:
all file and directories in a directory:
find ~/Downloads +time1000s
That finds what I need, then I run a conditional, if a dir exists, delete it, if not, create it:
mkdir -p ~/.Trash/safe-to-delte-these-old-files
This means I need to add print0 to my find as files will have spaces, and I want to move, not copy but either way, there is a source, and a destination, and I am getting stuck:
https://gist.github.com/5c0tt/5a2c1fd39ae99d6fca05
Line 27 and 26 seem to cause me issues, I am stuck.
Suggestions on everyone from line 1 to the end. I am trying to hard to do this with POSIX in mind, but i can't even get variables to work then.
It seems BSD does not work the exact same way as other shells and what arguments they accept, which is why I am trying to be more POSIX, as I was told it should run anywhere then.
Thank you.
Took a glance at your git link, a couple of remarks if I may (still a noob tbh so may be irrelevant) :
dir_to_clean="/Users/my_username/Downloads" should probably be dir_to_clean="/Users/$current_user/Downloads" unless you actually have a literal /Users/my_username/Downloads folder.
Instead of cd'ing into your users directory and since you have hardcoded the path to that directory, you could use pushd & popd instead in order to build a stack of directories.
To answer your question, to capture files with spaces in the name for removal you could use something like :
find $dir_to_clean -not -name . +time1000s -exec mv -- {} ~/.Trash/
Could be something like this :
# Initialise variables, user, source to clean, destination
user=$(whoami);
src="/Users/$user/Downloads";
dest="~/.Trash/safe_to_delete";
# Move to directory to clean, not necessary, but if you really want to
pushd $src;
# Check if the destination exists, if not, create it
if [ ! -d $dest ]; then
mkdir -p $dest;
else
echo "destination already exists";
fi
# Find all the file to move then move them
find . -not -name . +time1000s -exec mv -- {} "$dest/" \;
# Return to previous working directory
popd;
pushd the $src directory onto the stack. find all the files in the now current directory ., -not -name . in order to avoid trying to trash the . & .. folders, -- tells find to stop parsing command line options (in cas your file/folder is named i.e. -myfile.txt), exec mv all of the arguments to $dest. popd the still current directory off of the stack. man find (/exec) for more details.
Note : It is also interesting to know that the difference of execution time between the -exec option versus results being piped into xargs can and will often be quite dramatic. Also, if your are actually sure that those files are safe_to_delete, then delete them instead of moving them (-exec rm -- {} $dest/). With all that said, you were correct, one liner.

I need a script that will find and get me all files in all subdirectories (and leave them in the folder structure as they are now). I know how to find and print that files:
find . -name "something.extension"
The point is, in those directories are lots files that was used before, but I don't want to get those, so the script should only find me files that matches some kind of path pattern which is:
xxx/trunk/xxx/src/main/resources
xxx is different everytime, and after resources there are still some folders that directories are different based on xxx.
Every top xxx folder contains folder named 'tags' (the same level as trunk) that stores previous releases of module (and every release has files that name I am looking for, but I don't want outdated files).
So I want to find all that files in subdirectories of that path pattern that I specified and copy to new location but leave folder structure as it is right now.
I am using Windows and cygwin.
Update
I combined answer commands that 'that other guy' posted below, and it works. Just to be clear I have something like this:
find */trunk/*/src/main/resources -name "something.extension" -exec mkdir -p /absolute/target/path/{} \; -exec cp {} /absolute/target/path/{} \;
Thanks.
Instead of searching under the entire current directory (.), just search under the directories you care about:
find */trunk/*/src/main/resources -name "something.extension"
I have a lot of files named the same, with a directory structure (simplified) like this:
../foo1/bar1/dir/file_1.ps
../foo1/bar2/dir/file_1.ps
../foo2/bar1/dir/file_1.ps
.... and many more
As it is extremely inefficient to view all of those ps files by going to the
respective directory, I'd like to copy all of them into another directory, but include
the name of the first two directories (which are those relevant to my purpose) in the
file name.
I have previously tried like this, but I cannot get which file is from where, as they
are all named consecutively:
#!/bin/bash -xv
cp -v --backup=numbered {} */*/dir/file* ../plots/;
Where ../plots is the folder where I copy them. However, they are now of the form file.ps.~x~ (x is a number) so I get rid of the ".ps.~*~" and leave only the ps extension with:
rename 's/\.ps.~*~//g' *;
rename 's/\~/.ps/g' *;
Then, as the ps files have hundreds of points sometimes and take a long time to open, I just transform them into jpg.
for file in * ; do convert -density 150 -quality 70 "$file" "${file/.ps/}".jpg; done;
This is not really a working bash script as I have to change the directory manually.
I guess the best way to do it is to copy the files form the beginning with the names
of the first two directories incorporated in the copied filename.
How can I do this last thing?
If you just have two levels of directories, you can use
for file in */*/*.ps
do
ln "$file" "${file//\//_}"
done
This goes over each ps file, and hard links them to the current directory with the /s replaced by _. Use cp instead of ln if you intend to edit the files but don't want to update the originals.
For arbitrary directory levels, you can use the bash specific
shopt -s globstar
for file in **/*.ps
do
ln "$file" "${file//\//_}"
done
But are you sure you need to copy them all to one directory? You might be able to open them all with yourreader */*/*.ps, which depending on your reader may let browse through them one by one while still seeing the full path.
You should run a find command and print the names first like
find . -name "file_1.ps" -print
Then iterate over each of them and do a string replacement of / to '-' or any other character like
${filename/\//-}
The general syntax is ${string/substring/replacement}. Then you can copy it to the required directory. The complete script can be written as follows. Haven't tested it (not on linux at the moment), so you might need to tweak the code if you get any syntax error ;)
for filename in `find . -name "file_1.ps" -print`
do
newFileName=${filename/\//-}
cp $filename YourNewDirectory/$newFileName
done
You will need to place the script in the same root directory or change the find command to look for the particular directory if you are placing the above script in some other directory.

On a Mac, I have a directory of html files that are all document fragments. Using the TexFinderX app, I was easily able to do a find/replace and add everything at the top of the documents that I wanted (i.e. etc.) .
Now I need to find a way to add the closing tags to all of the documents (i.e. ). TexFinderX does not have a way to do this since the documents do not have anything in common at the end of the files.
Is there a Terminal command that can do this for all html files in a directory and it's subdirectories?
Thanks,
Linda
EDIT:
Well i was trying to keep it simple and avoid Bash scripting but it seems find doesnt allow for output redirection... so try this instead:
for f in ~/html/*.html; do echo "Processing $f file.." && cat ~/close.html >> $f; done
Put your closing tags in a file... well call it close.html and we'll jsut put it in your home directory /Users/youruser/close.html. Well assume your docs are in /Users/youruser/html
Open Terminal.app and do the following command:
find ~/html -type f -name "*.html" -exec cat ~/close.html >> {} \;
youll want to test that first... my find kung-fu is rusty
