I need to find all files in a directory and it's subdirectories, but I need to keep directory structure. For example there is a file
/media/subdir1/subdir2/file.jpg
and I want to copy it to
/new-media/subdir1/subdir2/file.jpg
and the same to all files inside /media/ directory. And by the way, directories inside /new-media/ must be created if not exist.
if I use
find /media/ -name '*.jpg' -exec cp /new-media/ ????? {} \;
how can I get all subdirectories inside /media/?
The above will get you everything in /media, but to get exactly what you want you probably want to use something like:
Method 1: Copy only what you need recursively, per your requirements:
mkdir ../media2; find . -name "*.jpg" -exec cp -r --parents {} ../media2 \;
I ran this from inside the directory you want to search recursively. It does a couple things:
1 - create the new destination directory
mkdir ../media2
2 - then finds all files ending with ".jpg" recursively.
find . -name "*.jpg"
3 - uses -exec to pass the copy command to each file returned to find as a match, and subs that in as the first argument (which with the syntax of cp, is going to be your source file):
-exec cp -r --parents {} ../media2 \;
the "--parents" flag retains existing directory structure and recursively creates subsequent parent directories. Super useful right?
Method 2: there might be a better way to do this with xargs, but the above ended up being the most simple method imho. That said, if you want to think outside the box, you could simply copy the entire directory over recursively, then remove anything NOT ending with ".jpg" with something like:
cp -r media media2; find ./media '!'-name "*.jpg" -type f | xargs rm
I think this is what you want:
cp -r /media /new-media
-R, -r, --recursive
copy directories recursively
Hope this helps.
I've a series of directories containing a set of files. There is a new copy of this file which I would like to replace all instances with. How can do this with find command?
Latest file is in /var/www/html is called update_user.php
There are 125 directories with several other files including a copy of update_user.php. I want to replace these with the one in update_user.php excluding itself.
This should do the job:
find /path/to/old/files -type f -name update_user.php -exec cp /path/to/new/update_user.php {} \;
You should check if the new file is not inside /path/to/old and if so than first copy it outside and use that copy but.. it'll not harm if you don't - one cp will fail with are the same file error.
You can use
cp -v to see what it does
cp -u to update only when source file is newer
echo cp to perform dry run
I would suggest to check first if all dest. files are the same with:
find /path/to/old/files -type f -name update_user.php -exec md5sum {} \;|awk '{print $1}'|sort|uniq
I'm making a bash script that should backup all files and dir structure to another dir.
I made the following code to do that:
find . -type f -exec cp {} $HOME/$bdir \; -o -type d -exec mkdir -p {} $HOME/$bdir \; ;
The problem is, is that this only copies the files and not the dir structure.
NOTE: I may not use cp -r, cp -R or something like it because this code is part of an assignment.
I hope somebody can put me in the right direction. ;)

EDIT:
I changed it to:
find . -type d -exec mkdir -p $HOME/$bdir/{} \; ;
find . -type f -exec cp {} $HOME/$bdir/{} \; ;
And it works! Ty guys ;)
This sounds like a job for rsync.
You mention that this is an assignment. What are your restrictions? Are you limited to only using find? Does it have to be a single command?
One way to do this is to do it in two find calls. The first call only looks for directories. When a directory is found, mkdir the corresponding directory in the destination hierarchy. The second find call would look for files, and would use a cp command like you currently have.
You can also take each filename, transform the path manually, and use that with the cp command. Here's an example of how to generate the destination filename:
> find . -type f | sed -e "s|^\./|/new/dir/|"
/new/dir/file1.txt
/new/dir/file2.txt
/new/dir/dir1/file1_1.txt
/new/dir/dir1/file1_2.txt
For your purposes, you could write a short bash script that take the source file as input, uses sed to generate the destination filename, and then passes those two paths to cp. The dirname command will return the directory portion of a filename, so mkdir -p $(dirname $destination_path) will ensure that the destination directory exists before you call cp. Armed with a script like that, you can simply have find execute the script for every file it finds.
cd olddir; tar c . | (cd newdir; tar xp)
Can you do your find with "-type d" and exec a "mkdir -p" first, followed by your find that copies the files rather than having it all in one command? It should probably also be mkdir -p $HOME/$bdir/{}.
I was in the process of creating a User class where one of the methods was get_privileges();.
After hours of slamming my head into the keyboard, I finally discovered that the previous coder who I inherited this particular database spelled the word "privileges" as "privelages" in the MySQL database, and thus also everywhere in the hundreds of files that access these "privelages" it is spelled that way.
Is there a way in Linux (Ubuntu Server) that I can go through every place in the /var/www folder and replace "privelages" with "privileges", so that I don't have to deal with this typo and code around it?
A variation that takes into account subdirectories (untested):
find /var/www -type f -exec sed -i 's/privelages/privileges/g' {} \;
This will find all files (not directories, specified by -type f) under /var/www, and perform a sed command to replace "privelages" with "privileges" on each file it finds.
Check this out: http://www.cyberciti.biz/faq/unix-linux-replace-string-words-in-many-files/
cd /var/www
sed -i 's/privelages/privileges/g' *
I generally use this short script, which will rename a string in all files and all directory names and filenames. To use it, you can copy the text below into a file called replace_string, run sudo chmod u+x replace_string and then move it into your sudo mv replace_string /usr/local/bin folder to be able to execute it in any directory.
NOTE: this only works on linux (tested on ubuntu), and fails on MacOS. Also be careful with this because it can mess up things like git files. I haven't tested it on binaries either.
#!/usr/bin/env bash
# This will replace all instances of a string in folder names, filenames,
# and within files. Sometimes you have to run it twice, if directory names change.
# Example usage:
# replace_string apple banana
echo $1
echo $2
find ./ -type f -exec sed -i -e "s/$1/$2/g" {} \; # rename within files
find ./ -type d -exec rename "s/$1/$2/g" {} \; # rename directories
find ./ -type f -exec rename "s/$1/$2/g" {} \; # rename files
I want to create a clone of the structure of our multi-terabyte file server. I know that cp --parents can move a file and it's parent structure, but is there any way to copy the directory structure intact?
I want to copy to a linux system and our file server is CIFS mounted there.
You could do something like:
find . -type d > dirs.txt
to create the list of directories, then
xargs mkdir -p < dirs.txt
to create the directories on the destination.
cd /path/to/directories &&
find . -type d -exec mkdir -p -- /path/to/backup/{} \;
Here is a simple solution using rsync:
rsync -av -f"+ */" -f"- *" "$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)

[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
FYI:
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
