Shell command to tar directory excluding certain files/folders
Shell command to tar directory excluding certain files/folders
Question
Is there a simple shell command/script that supports excluding certain files/folders from being archived?
I have a directory that need to be archived with a sub directory that has a number of very large files I do not need to backup.
Not quite solutions:
The tar --exclude=PATTERN command matches the given pattern and excludes those files, but I need specific files & folders to be ignored (full file path), otherwise valid files might be excluded.
I could also use the find command to create a list of files and exclude the ones I don't want to archive and pass the list to tar, but that only works with for a small amount of files. I have tens of thousands.
I'm beginning to think the only solution is to create a file with a list of files/folders to be excluded, then use rsync with --exclude-from=file to copy all the files to a tmp directory, and then use tar to archive that directory.
Can anybody think of a better/more efficient solution?
EDIT: Charles Ma's solution works well. The big gotcha is that the --exclude='./folder' MUST be at the beginning of the tar command. Full command (cd first, so backup is relative to that directory):
cd /folder_to_backup
tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .
Accepted Answer
You can have multiple exclude options for tar so
$ tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .
etc will work. Make sure to put --exclude before the source and destination items.

You can exclude directories with --exclude for tar.
If you want to archive everything except /usr you can use:
tar -zcvf /all.tgz / --exclude=/usr
In your case perhaps something like
tar -zcvf archive.tgz arc_dir --exclude=dir/ignore_this_dir
Possible options to exclude files/directories from backup using tar:
Exclude files using multiple patterns
tar -czf backup.tar.gz --exclude=PATTERN1 --exclude=PATTERN2 ... /path/to/backup
Exclude files using an exclude file filled with a list of patterns
tar -czf backup.tar.gz -X /path/to/exclude.txt /path/to/backup
Exclude files using tags by placing a tag file in any directory that should be skipped
tar -czf backup.tar.gz --exclude-tag-all=exclude.tag /path/to/backup
old question with many answers, but I found that none were quite clear enough for me, so I would like to add my try.
if you have the following structure
/home/ftp/mysite/
with following file/folders
/home/ftp/mysite/file1
/home/ftp/mysite/file2
/home/ftp/mysite/file3
/home/ftp/mysite/folder1
/home/ftp/mysite/folder2
/home/ftp/mysite/folder3
so, you want to make a tar file that contain everyting inside /home/ftp/mysite (to move the site to a new server), but file3 is just junk, and everything in folder3 is also not needed, so we will skip those two.
we use the format
tar -czvf <name of tar file> <what to tar> <any excludes>
where the c = create, z = zip, and v = verbose (you can see the files as they are entered, usefull to make sure none of the files you exclude are being added). and f= file.
so, my command would look like this
cd /home/ftp/
tar -czvf mysite.tar.gz mysite --exclude='file3' --exclude='folder3'
note the files/folders excluded are relatively to the root of your tar (I have tried full path here relative to / but I can not make that work).
hope this will help someone (and me next time I google it)
You can use standard "ant notation" to exclude directories relative.
This works for me and excludes any .git or node_module directories:
tar -cvf myFile.tar --exclude=**/.git/* --exclude=**/node_modules/* -T /data/txt/myInputFile.txt 2> /data/txt/myTarLogFile.txt
myInputFile.txt contains:
/dev2/java
/dev2/javascript
I've experienced that, at least with the Cygwin version of tar I'm using ("CYGWIN_NT-5.1 1.7.17(0.262/5/3) 2012-10-19 14:39 i686 Cygwin" on a Windows XP Home Edition SP3 machine), the order of options is important.
While this construction worked for me:
tar cfvz target.tgz --exclude='<dir1>' --exclude='<dir2>' target_dir
that one didn't work:
tar cfvz --exclude='<dir1>' --exclude='<dir2>' target.tgz target_dir
This, while tar --help reveals the following:
tar [OPTION...] [FILE]
So, the second command should also work, but apparently it doesn't seem to be the case...
Best rgds,
