I am not familiar with osx terminal command.
I have a java project containing many package.
Some classes have same name in different package.
I need to copy all of the class files into a directory, so I need to add
corresponding package prefix on each files.
For example, I have root/com/example1/test.java and root/com/example2/test.java two classes having the same name in different packages. I need to copy them into root directory and add prefix, making them become example1.test.java and example2.test.java in root directory.
How to do this using terminal command?
This solution is not perfect but it should do what you want (assuming I understood your question correctly):
Create a file doCopy.sh with the following content:
#!/bin/bash
origName=$1
newName=$(echo $origName | sed -e 's|/|.|g')
echo cp $origName $newName
Then make it executable and call it for each of your files:
chmod +x doCopy.sh
find root -type f -exec ./doCopy.sh {} \;
Please verify the commands that will be printed. If you are satisfied you can remove the echo from doCopy.sh and rerun the find to actually copy the files.

I'm not allowed to use rsync on the cluster I'm working on so I need to use cp. I want to copy a large directory including all files and subfolders etc. but without any folders that have the name "outdir".
I tried cp -r -v ./!(outdir) ../target-directory/
but it still copies all folders and contents in deeper directories with the name outdir. It only included the outdir folders in the highest directory.
I also tried cp -r ./*/!(outdir) ../target-directory/ but that one copied all files into the folder without keeping any hirarchy or folders etc.
I also tried certain find commands but it didn't work, but maybe I was just doing something stupid. I'm a beginner with bash so if you could explain your answer and what the flags etc. do that would really be helpfull, I've been trying forever now, on what I think shouldn't be that hard to do.
Instead of cp, you can use tar with option --exclude to control what you want copied or not.
The full command is:
tar --exclude="outdir" -cvpf - . | (cd TARGET_DIRECTORY; tar -xpf -)
So any path that contains the "outdir" pattern will be excluded.
Without the --exclude option, it will copy the entire structure of your current directory under TARGET_DIRECTORY.
You can replace the . in the first tar by your desired source directory.
I want to use the find command to execute a special command on all of the files inside the directory that are contained inside multiple different directories with a specific keyword in it (the keyword is "Alpha") and keep the output inside the working directory of the initial file I ran the command on.
The command works such that it requires to you to provide the initial file to perform the command on and then the name of the newly converted file. So like this
command file_to_run_command_on.txt new_file.txt
This is my code
find $PWD -name *.txt* -exec command {} new_file. \;
Right now, it finds all the text files in this directory even in the sub directories and outputs just one file in the directory I run the initial find command from. I'm also unsure how to add the additional search for the keyword in the directory. All advice appreciated!
-exec runs the command in the directory from which you start find.
-execdir runs the command in the matching file's directory.
To only find *.txt* files whose parents contain a specific file, you could use:
find "$PWD" -path "*keyword*/*.txt*" -execdir command {} new_file \;
This will run the command for foo/bar/some-keyword-dir/baz/etc/file.txts but not for foo/bar/baz/file.txts (no keyword in parent directory names) or foo/bar/some-keyword-dir/baz/file.tar (not *.txt*)
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 currently have a set of folders that I need to duplicate the structure into another folder.
I currently work with photos that are dumped into a Dump folder in groups.
Eg.
Photo Dump
Group1
Group2 etc
I would like to have a script to recreate these folders without the files to the good folder so that I don't have to recreate them manually
Any ideas?

If I understand correctly, you want to copy the parent folder and all of its subfolders, but none of the files contained therein. There might be a simpler way, but I just threw together this Terminal command (which should also work on Linux or anywhere else with Bash):
ls -R | grep :$ | sed 's/\.\/\(.*\):$/\1/' | \
while read thisFolder; do mkdir -p "destination"/"$thisFolder"; done
It will copy the folder structure of all folders in the current directory into a folder called "destination"; you can of course change this to any path you wish, e.g. ~/Desktop/"Folder Copies" or whatever.
Take care to first "cd" into whatever directory contains the folder tree you want to duplicate, because if you run it as soon as you open the terminal, you'll wind up with a replication of your entire home folder directory structure, including the many contained within Library.
I found this to be a tad clearer:
find 'Photo Dump' -type d | sed -e 's:^Photo Dump:destination:g' | sort | xargs mkdir
find 'Photo Dump' -type d -> List all folders in "Photo Dump"
sed -e 's:^Photo Dump:destination:g' - Since all folders listed in the above step will start with Photo Dump/..., we can just replace the beginning with the folder we want to copy the structure to (in this case I called it destination)
sort - Sorts results. This is required so that the parent folders are created before the children
xargs mkdir - Passes all the results from above into mkdir so it can create the folders
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.
