I need an easy way to take a tar file and convert it into a string (and vice versa). Is there a way to do this in Ruby? My best attempt was this: file = File.open("path-to-file.tar.gz") contents = "" file.each {|line| contents << line } I thought that would be enough to convert it to a string, but then when I try to write it back ou...
I've got a script that tars an entire source code directory (around 800MB), and I want it to run as fast as possible. GNU Tar, for some reason, was kind of slow when untarring. I was wondering if anyone's already made this comparison and knows which application has the fastest tar/untar implementation. For Windows, btw. ...
I'm trying to tar up all the *.class files only on a Solaris box under a certain directory. Reading the man pages for tar made it seem like the -I option is what I wanted. This is what I've tried from the dir in question: find . -name "*.class" >> ~/includes.txt tar cvf ~/classfiles.tar -I ~/includes.txt From that I get: tar: Removi...
I'm extracting a folder from a tarball, and I see these zero-byte files showing up in the result (where they are not in the source.) Setup (all on OS X): On machine one, I have a directory /My/Stuff/Goes/Here/ containing several hundred files. I build it like this tar -cZf mystuff.tgz /My/Stuff/Goes/Here/ On machine two, I scp the t...
Working in an AIX environment, I'm issuing the following tar command and receive errors on sockets. Question 1. How can I avoid the socket errors? Question 2. Can I rely on the tar file to contain all files excluding the ones in error? $ tar -cvf /post_patches.tar /xyz tar: /xyz/runtime/splSock6511 could not be archived tar...
How do I extract a tar (or tar.gz, or tar.bz2) file in Java? ...
I saw the following interesting usage of tar in a co-worker's Bash scripts: `tar cf - * | (cd <dest> ; tar xf - )` Apparently it works much like rsync -av does, but faster. The question arises, how? -m EDIT: Can anyone explain why should this solution be preferable over the following? cp -rfp * dest Is the former faster? ...
Hi, I'm working on a java web application that uses thousands of small files to build artifacts in response to requests. I think our system could see performance improvements if we could map these files into memory rather than run all over the disk to find them all the time. I have heard of mmap in linux, and my basic understanding of...

We are currently using SharpZipLib but since it uses the GPL we need to replace it with a commercial lib. ...
I'm using Ant 1.7.1 to tar up the contents of a directory, that contains a .git subdirectory. My current task is <tar destfile="sali-src-${version}.tgz" basedir="${basedir}" compression="gzip" excludes=".git, .gitignore, *.ipr, *.iws, *.iml"> </tar> But the resultant tarball contains the .git subdirectory. Could anybod...
I use Cygwin regularly, but I have a need these days to extract tar.gz and tar.bz2 files on other people's Windows machines. They don't want Cygwin; they need a GUI. I've tried 7-zip, which some other people in our company were using, but 7-zip makes the braindead decision to require you to first uncompress a file to a new destination ...
I have a directory I’m archiving: $ du -sh oldcode 1400848 $ tar cf oldcode.tar oldcode So the directory is 1.4gb. The file is significantly smaller, though: $ ls -l oldcode.tar -rw-r--r-- 1 ieure ieure 940339200 2002-01-30 10:33 oldcode.tar Only 897mb. It’s not compressed in any way: $ file oldcode.tar oldcode.tar: POSIX tar arch...
I want to archive a directory (I don't know whether I can call "I want to tar a directory"). I want to preserve the access permissions at the other end when I un-tar it. I should I tackle this problem in perl. Thanks for the response but why I'm asking for doing it Perl is I want it independent of the platforms. I want to transfer one ...
I need to regularly send a collection of log files that can grow quite large, so I would like to only send the last n lines of the each of the files. for example: /usr/local/data_store1/file.txt (500 lines) /usr/local/data_store2/file.txt (800 lines) Given a file with a list of needed files named files.txt, I would like to create an...

I have this home work where I have to transfer a very big file from one source to multiple machines using bittorrent kinda of algorithm. Initially I am cutting the files in to chunks and I transfer chunks to all the targets. Targets have the intelligence to share the chunks they have with other targets. It works fine. I wanted to transfe...
I'm archiving a directory. This directory has a file that is being written by another process. When I tar this using Linux tar/Perl Tar module, in the archive the entry for the file is there but the contents are null.

I'm using Perl's Archive::Tar module. It preserves the file permissions but doesn't preserve the sticky bit. At the other end where I extract the archive, all the sticky bits are gone. I think UNIX/LINUX operating system stores these sticky bits somewhere else. How can I make my archive preserve sticky bits also? Using the -p switch to ...
