Ubuntu :: How To Extract Split Compressed Files
Jun 24, 2010
im trying to reconstruct / extract a file that was too large to fit onto a floppy, used 7zip to create and split the file into multiple parts in tar.bzip format. this was done in windows. Then moved all the parts of the file to tiny linux on a really old laptop. no cd drive, no usb or network. so have to rely on floppy drive. i do know that reconstruction while extracting using commands is possible. but not working.tried tar -xMf file.tar.001 but nothing.

I have a text file of n-number of tab-delimited lines ("INPUT") which I would like to parse line-by-line to a text output file depending on the SampleID of the line. These lines contain a unique SampleID and each subject has several lines of data.
[code]....
I also have a text file of relevant SampleID ("INPUT2"). The basic idea is that I read a line from INPUT, split the tab-delimited line, extract the SampleID from the split line, compare the SampleID of this line to my list of relevant SampleIDs. If there is a match, then print the line from INPUT to OUTPUT, then move on to the next line of INPUT. Alternatively, if there is no match, then move on to the next line in INPUT. I tried to script this (extreme newbie at perl right now) and failed miserably, but here is what I have at the moment:

I was trying to figure out how to generate compressed files in zip format and searched on here. The search produced a list of forum entries on the topic, but all of the instructions were on how to do it in terminal, how to download obscure programs and install them from terminal, then run them from terminal, with all these arcane sets of switches and parameters. Eesh.
It comes with Ubuntu, after all. In the case of zipping files, all you have to do is to go to the File Manager, find the file(s), select it or them, right-click on it or them, and select Compress and file type zip. It's so simple.
There have been a number of other tasks where I wind up spending hours figuring out how to implement the advice offered in these forums through Terminal. The folks who offer the advice often are so good at it that they leave out steps obvious to them, but that take a lot of work for somebody not as skilled at it to find out. After crawling through broken glass to get the job done, and normally screwing something up so it's not quite right once I get it going, I figure out how to do it through the GUI and find out it takes a fraction of the effort.

When trying to create a new compressed/archive file in Gnome Commander (GM) the file is created but the selected files are not added. I can open the new (empty) archive file and then add files to be compressed. I have tried using several different formats (zip, tar.bz and others) with the same results. The "file roller" is shown as a plugin but has no configuration other than the compressed file type.

I am using rsync to create rotating snapshot style backups of my web files and sending them via SSH to a remote location in order to burn them for offsite storage. This is all working perfect. The remote machine is a Windows Server 2003 which has data that I combine with my web files before burning. I have cygwin installed on the remote server in order to archive and compress the entire backup using tar. (This is not a post about cygwin, I just thought I would mention it in case anyone was wondering how I was running Linux commands after transferring it to the Windows box). After compression, the backup is over 12gb. The next step in my process is to split this tar.gz file into smaller chunks in order to burn them to DVDs. I use dual layer DVDs which are 8.5gb storage size.
I also use cygwin to split the tar.gz into multiple 2gb files using the split command. When I burn them, I only put 3 files on each disk totaling 6gb to leave some padding in case this was a problem. The burn completes and says successful, although it errors out when in verification. I have tried this multiple times and it seems to fail verification at the same point every time which leads me to believe that it has something to do with the data. I have also done tests such as creating smaller backups with completely different data and brning that to a CD-R which worked fine, so I'm convinced this process can work, I just cant get it to work in the right situation. I have also tried burning one of the 7 split files to a dual DVD which also worked fine. I'm wondering if their is a chunk of data that is causing this problem in one of the other split files?

I'm looking for a free alternative to split files into .partXX files. I know this can be accomplished through rar, but it's a shareware and I was wondering if there's a free alternative that accomplishes the same job.

I have a file of +1 1GB in size. I want to split it in either 100MB rar files or 100MB zip files.
Anybody know what command I need for this?
Please keep it simple, I'm very new to linux. So I'm hoping somebody can give me a command in the lines of "blabla "put file name here" "put file size here" "put folder to rar/zip" here.

Rather simple question, but is there a way to make an archive (simple tarball, no compression needed) out of a very large file and split it into parts? Basically I need a ~1GB file in 25MB pieces.

I came across this feature of the "less" command today. It appears not to be well-documented so I'll share it here. I found that "less" can automatically uncompress compressed files - no need to run the first command, the second does the same job:
Code:
gunzip -c textfile.gz | less
less textfile.gz
Even better, "less" can read and list the contents of some archive files as well, including Tar files compressed using Gzip and Bzip2 as well as Zip files. So now when I want to list the contents of an archive,for example to determine whether the contents will be extracted to an absolute path or relative to the working directory, the following work
Code:
less archive.tar.gz
less archive.tgz
less archive.tar.bz2
less archive.zip
Much easier than remembering the various options that the Tar, Gzip, Bzip2 and Zip use. The best one for me is with RPM archives:
Code:
less some.rpm
The above outputs the Information, Change Log and verbose File List of the RPM (paging the output, of course!) The following commands (using short and long options) give the equivalent output using the "rpm" command:
Code:
rpm -qilvp --changelog some.rpm | less
rpm --query --info --list --verbose --package --changelog some.rpm | less
"less" does not recognise the initramfs file produced by "dracut" (which is a compressed "cpio" archive), but I suppose you can't have everything ...

I am running Ubuntu 11.04 and just tried to install VLC. I download the .zip file and once it loaded, I tried to extract it. The following error came up:
tar (child): /tmp/vlc-1.1.4.tar.bz2: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
What is the correct method to unzip and install this (or any other .zip file for that matter?)

streaming videos i sometime want to save them, after watching. generally they're saved as flash videos or mpeg-4 video, which is all fine.however periodically they're split-up and saved in smaller chunks with names like data_1, data_2, data_3 etc. these range from 14.0 - 44.0 MB. the file in question (currently i'm trying to save from the cache) was from divxden, or possibly divxstage.eu either way i think it used the totem plugin.so, my question is: does anyone know if these files can be stuck back together, or if this feature can be changed so streamed files are kept intact?

I need to split up a large file on windows so I can upload it in parts to a linux machine. I'm looking to do the opposite to this hopefully with some native utilities to keep it simple.
I understand the linux side of the equation to be cat filea fileb > file
what is the simples way to split files on a windows machine which can then be joined together via cat on a linux machine?

OK, So I'm trying to make a SFX file that will extract it's files your home folder, But I can't seem to figure out how.
First you have to make an archive,
Code:
rar a Zipper.zip txt.txt
Then you have to make the sfx.
Code:
rar s Zipper.zip
But they still get extracted wherever the sfx volume is.
