How can i copy only header files in an entire nested directory to another directory keeping the same hierarchy after copying to new folder - linux

I have a directory which has a lot of header files(.h) and other .o and .c files and other files.
This directory has many nested directories inside. I want to copy only header files to a separate directory preserving the same structure in the new directory.
cp -rf oldDirectory newDirectory will copy all files.
I want to copy only header files.

(cd src && find . -name '*.h' -print | tar --create --files-from -) | (cd dst && tar xvfp -)
You can do something similar with cpio if you just want to hard link the files instead of copying them, but it's likely to require a little mv'ing afterward. If you have lots of data and don't mind (or need!) sharing, this can be much faster. It gets confused if dst needs to have a src in it - this is, if it isn't just a side effect:
find src -name '*.h' -print | cpio -pdlv dst
mv dst/src/* dst/.
rmdir dst/src

this one worked for me:
rsync -avm --include='*.h' -f 'hide,! */' . /destination_dir
from here

cp -rf oldDirectory/*.h newDirectory
or something like (depending on the actual paths)
find oldDirectory -type f -name "*.h" -print0 | xargs -file cp file newDirectory

In BASH, how do you reference a directory name in a copy statement of files you recursively "find"

I want to recursively find all files that end with *DETAIL.pdf
Create a new directory (in another drive) for each file with the same name as the original directory
Copy the file into the new directory
I have this as my current attempt:
find . -name \*DETAIL.pdf -type f -not -path "./test2" -exec cp -R {} ./test2 \;
I am struggling to create new directories for all these files by referencing the original directory name of each file.
The example mentions using cp but the question/problem itself does not, so I would suggest just using find and tar. Also, though the question is a little ambiguous as noted in the comments above, the example seems to suggest that the desired output directory is a child of the same directory being searched. Given that:
find . -path "./test2" -prune -o -type f -name '*DETAIL.pdf' -print0 | \
tar c --null --files-from=- | \
tar xC test2
This uses find for file selection, generating a (null-separated) file list, which tar then uses to copy the files, and the second tar will create the relative directories as needed and write the copied files.

Linux: copy ".svn" directories recursively

I know there are dozen of questions about similar topcis but I still can't beat this up.
I need to copy all .svn directories recursively from /var/foo to /var/foo2 on a Debian machine:
/var/www/foo/.svn
/var/www/foo/bar/.svn
...
I tried these two commands without success:
find /var/foo -name ".svn" -type f -exec cp {} ./var/foo2 \;
find /var/foo -name ".svn" -type d -exec cp {} /var/foo2 \;
Once only the svn directory right inside foo is copied, while another time nothing is copied.
Given following file structure:
./
./a/
./a/test/
./a/test/2
./b/
./b/3
./test/
./test/1
Running following script in the directory to be copied:
find -type d -iname test -exec sh -c 'mkdir -p "$(dirname ~/tmp2/{})"; cp -r {}/ ~/tmp2/{}' \;
Should copy all test directories to ~/tmp2/.
Points of interest:
Directories are copied to the destination on a one-by-one basis
Parent directories are created in advance so that cp doesn't complain about target not existing
Rather than just cp, cp -r is used
The whole command is wrapped with sh -c so that operations on {} such as dirname can be performed (so that the shell expands it for each directory separately, rather than expanding it once during calling the find)
Resulting structure in ~/tmp2:
./
./a/
./a/test/
./a/test/2
./test/
./test/1
So all you should need to do is to replace test with .svn and ~/tmp2 with directory of choice. Just remember about running it in the source directory, instead of using absolute paths.
I find that using tar for such operations makes the code often much more readable:
$ mkdir /var/www/foo2
$ cd /var/www/foo2
$ find ../foo/ -type d -name .svn -exec tar c \{\} \+ | \
tar x --strip-components=1
find will list all directories named .svn, and call tar to create (c) an archive file (that is sent to stdout) with all these directories. the archive on stdout is then extracted (x) by another tar instance in the target directory. the relative path portion (../) is automatically removed by the archiving tar, but since we also want to remove the first path component (foo/) we need to add --strip-components.
Note: This will only work if you do not have very many .svn directories you want to copy (more than $(getconf ARG_MAX)-2, which on my system is more than 200000).

copy entire directory excluding a file

As we know, cp -r source_dir intended_new_directory creates a copy of source directory with a new name. Now I want to do the same but want to exclude a particular file. I have found some related answers here, using tar and rsync, but in those solutions I need to create the destination directory first (using mkdir).
I honestly searched a lot, but didn't find exactly what I want.
So far the best I got is this:
tar -c --exclude=\*.dll --exclude=\*.exe sourceDir | tar -x -C destDir
(from http://www.linuxquestions.org/questions/programming-9/how-to-copy-an-entire-directory-structure-except-certain-files-385321/)
If you have binutils, you could use find to filter next cpio to copy (and create directories) :
find <sourceDir> \( ! -name *.dll \) -a \( ! -name *.exe \) | cpio -dumpv <destDir>
Try this by excluding the file using 'grep -v' ->
cp `ls | grep -v <exclude-file>` <dest-dir>
If the directory is not very large I used to write something like this:
src=path/to/source/directory
dst=path/to/destination/directory
find $src -type f | while read f ; do mkdir -p "$dst/`dirname $f`"; cp "$f" "$dst/$f" ; done
Here we list all regular files in $src, iterate over this list and for each file make a directory in $dst if it does not exist yet (-p option of mkdir), then copy the file to that directory.
The above command will copy all the files. Finally, just use
find $src -type f | grep -v whatever | while ...... # same as above
to filter out the files you don't need (e.g. \.bak$, \.orig$, or whatever files you don't want to copy).
Move all exclude file into home or other directory,copy the directory containing all remaining files to the destination folder then restore all exclude files.
#cd mydirectory
#mv exclude1 exclude2 /home/
#cp mydirectory destination_folder/
#cd /home/
#mv eclude1 exclude2 mydirectory/

Copy modified files with directory structure in linux

How can I copy a list of files modified today with the directory structure into a new directory. As shown in the following command I want to copy all the files modified today from /dev1/Java/src into /dev2/java/src. The src folder has many sub directories.
find /dev1/Java/src -newermt 2014-06-10 > 1.txt
for f in $(cat 1.txt) ; do cp $f /dev2/Java/src; done
You can take advantage of find and cpio utility.
cd /dev1/Java/src; find . -mindepth 1 -mtime -1 | cpio -pdmuv /dev2/Java/src
The above command goes to the source directory and finds the list of new files relative to the source directory.
The output is read by cpio and copies the files into the target directory in the same structure as the source, hence the need for relative pathnames.
Extracts the files modified within a day and copies them to the desired path.
find . -type f -mtime -1 -exec cp {} /path \;

Copy folder structure (without files) from one location to another

I want to create a clone of the structure of our multi-terabyte file server. I know that cp --parents can move a file and it's parent structure, but is there any way to copy the directory structure intact?
I want to copy to a linux system and our file server is CIFS mounted there.
You could do something like:
find . -type d > dirs.txt
to create the list of directories, then
xargs mkdir -p < dirs.txt
to create the directories on the destination.
cd /path/to/directories &&
find . -type d -exec mkdir -p -- /path/to/backup/{} \;
Here is a simple solution using rsync:
rsync -av -f"+ */" -f"- *" "$source" "$target"
one line
no problems with spaces
preserve permissions
I found this solution there
1 line solution:
find . -type d -exec mkdir -p /path/to/copy/directory/tree/{} \;
I dunno if you are looking for a solution on Linux. If so, you can try this:
$ mkdir destdir
$ cd sourcedir
$ find . -type d | cpio -pdvm destdir
This copy the directories and files attributes, but not the files data:
cp -R --attributes-only SOURCE DEST
Then you can delete the files attributes if you are not interested in them:
find DEST -type f -exec rm {} \;
This works:
find ./<SOURCE_DIR>/ -type d | sed 's/\.\/<SOURCE_DIR>//g' | xargs -I {} mkdir -p <DEST_DIR>"/{}"
Just replace SOURCE_DIR and DEST_DIR.
The following solution worked well for me in various environments:
sourceDir="some/directory"
targetDir="any/other/directory"
find "$sourceDir" -type d | sed -e "s?$sourceDir?$targetDir?" | xargs mkdir -p
This solves even the problem with whitespaces:
In the original/source dir:
find . -type d -exec echo "'{}'" \; > dirs2.txt
then recreate it in the newly created dir:
mkdir -p <../<SOURCEDIR>/dirs2.txt
Substitute target_dir and source_dir with the appropriate values:
cd target_dir && (cd source_dir; find . -type d ! -name .) | xargs -i mkdir -p "{}"
Tested on OSX+Ubuntu.
If you can get access from a Windows machine, you can use xcopy with /T and /E to copy just the folder structure (the /E includes empty folders)
http://ss64.com/nt/xcopy.html
[EDIT!]
This one uses rsync to recreate the directory structure but without the files.

Might actually be better :)
A python script from Sergiy Kolodyazhnyy
posted on Copy only folders not files?:
#!/usr/bin/env python
import os,sys
dirs=[ r for r,s,f in os.walk(".") if r != "."]
for i in dirs:
os.makedirs(os.path.join(sys.argv[1],i))
or from the shell:
python -c 'import os,sys;dirs=[ r for r,s,f in os.walk(".") if r != "."];[os.makedirs(os.path.join(sys.argv[1],i)) for i in dirs]' ~/new_destination

Copy top level folder structure without copying files in linux
How do I copy a directory tree but not the files in Linux?
Another approach is use the tree which is pretty handy and navigating directory trees based on its strong options. There are options for directory only, exclude empty directories, exclude names with pattern, include only names with pattern, etc. Check out man tree
Advantage: you can edit or review the list, or if you do a lot of scripting and create a batch of empty directories frequently
Approach: create a list of directories using tree, use that list as an arguments input to mkdir
tree -dfi --noreport > some_dir_file.txt
-dfi lists only directories, prints full path for each name, makes tree not print the indentation lines,
--noreport Omits printing of the file and directory report at the end of the tree listing, just to make the output file not contain any fluff
Then go to the destination where you want the empty directories and execute
xargs mkdir < some_dir_file.txt
find source/ -type f | rsync -a --exclude-from - source/ target/
Copy dir only with associated permission and ownership
Simple way:
for i in `find . -type d`; do mkdir /home/exemplo/$i; done
cd oldlocation
find . -type d -print0 | xargs -0 -I{} mkdir -p newlocation/{}
You can also create top directories only:
cd oldlocation
find . -maxdepth 1 -type d -print0 | xargs -0 -I{} mkdir -p newlocation/{}
Here is a solution in php that:
copies the directories (not recursively, only one level)
preserves permissions
unlike the rsync solution, is fast even with directories containing thousands of files as it does not even go into the folders
has no problems with spaces
should be easy to read and adjust
Create a file like syncDirs.php with this content:
<?php
foreach (new DirectoryIterator($argv[1]) as $f) {
if($f->isDot() || !$f->isDir()) continue;
mkdir($argv[2].'/'.$f->getFilename(), $f->getPerms());
chown($argv[2].'/'.$f->getFilename(), $f->getOwner());
chgrp($argv[2].'/'.$f->getFilename(), $f->getGroup());
}
Run it as user that has enough rights:
sudo php syncDirs.php /var/source /var/destination
