I use a tar command like this:
tar -cf backupdb/db/2012/11/database.2012-11-25.tar.gz backupdb/db/2012/11/25/*.sql
But when I open the tar file I see a directory backupdb/db/2012/11/25 :/
How to modify the command to compress files backupdb/db/2012/11/25/*.sql but without parent directories.
I know the -C switcher in tar command, but I don't know how to use it to compress files with specify exptension.
You are looking for the -C flag:
tar -C backupdb/db/2012/11/25/ -cf backupdb/db/2012/11/database.2012-11-25.tar.gz *.sql

As titled. I want to use some command, like for .zip files I can say
unzip myfiles.zip -d mydirectory
But is there a thing for .tar file on Mac as well?
Yes, you can run:
tar -xvf myfile.tar
For .tar.gz, you can run:
tar -xzvf myfile.tar.gz
If you want to extract to any directory other than your cwd, use -C. e.g:
tar -xvf myfile.tar -C somedirectory
I suggest you read the man page for tar if you wish to do anything further:
man tar
I am trying to compress a log file directory on my mac. The log directory exists.
For example /var/logs/my_log_dir/
I am trying to run something like:
$ tar –cpzf x.tar.gz /var/logs/my_log_dir
I also tried other variations such as compressing only one of the files in the log dir - no luck. All I get from my mac is:
Usage:
List: tar -tf <archive-filename>
Extract: tar -xf <archive-filename>
Create: tar -cf <archive-filename> [filenames...]
Help: tar --help
Thoughts?
Using -p doesn't make sense in the context of compression, since you're already shoving in whatever permissions are on the files by default. When extracting, however, you can use the -p flag if you're concerned about permissions.
Compress: tar –czvf x.tar.gz /var/logs/my_log_dir
Extract: tar –xpzvf x.tar.gz
-p option (preserve file permissions) works in x mode only.
I have a file named 2014-03-19_cis_digital.tar.gz. in a source directory, i will have to first GUNZIP the file and then UNTAR the file and move the untarred files to another directory.
Can anyone help me in writing the shell script commands??
change your working directory first then untar/ungzip.
cd $TARGET_DIR
tar xzf $PATH_TO_FILE
You don't need to gunzip separately. You can do everything in one command:
tar -xzf /source/dir/2014-03-19_cis_digital.tar.gz -C /target/dir
I have a tar archive which contains several text files. I would like to write a script to display (stdout) the content of a file without extracting it to the current directory.
Actually I would like to do the same as:
tar tf myArchive.tar folder/someFile.txt
cat folder/someFile.txt
rm -R folder
but without the rm...
I tried this way but it didn't work:
tar tf myArchive.tar folder/someFile.txt | cat
Thanks
Use x to extract, with f from archive file. Then add also option -O to direct extracted files to standard output.
tar xf myArchive.tar folder/someFile.txt -O
I have a tarball, myarchive.tar.gz. When I uncompress it using "tar -zxvf myarchive.tar.gz", it creates a folder myarchive-x980-2303-ssioo. What's the easiest way to automatically rename the extracted folder to ensure it matches the name of the archive? I've checked tar's manpage, but it doesn't seem to have an option for this.
Manually create folder, and strip components from tarball:
archive=my.tar.gz
mkdir ${archive%.tar*}
tar --extract --file=${archive} --strip-components=1 --directory=${archive%.tar*}
mkdir pretty_name && tar xf ugly_name.tar -C pretty_name --strip-components 1
