Talk:Cpio
From Wikipedia, the free encyclopedia
curious: how does cpio differ from tar or shar and why might it be preferable? Derex @ 20:55, 8 October 2005 (UTC)
- Many versions of the tar utility, especially on legacy systems, only support a single archive format. The GNU cpio utility (and, typically, other cpio implementations), supports multiple archive formats. One of them, usually referred to as POSIX tar is actually compatible with existing tar utilities, so one can use:
$ find dir/ | cpio -o -H ustar > dir.tar $ tar tvf dir.tar | more
- So, in a sence, cpio provides a superset of the functionality of tar.
- It's worth noting though that many modern tar implementations support a variety of formats too, i.e. the tar(1) utility of recent FreeBSD versions, so this distinction has started to blur and/or fade away a bit.
- Other important differences include:
- cpio uses stdin to read the list of files to archive, making it easy to exclude certain patterns of files by grepping them out, making concatenation of file lists easy, etc.
- cpio has a pass-through mode, which wasn't available in early tar versions
- more...

[edit] Duplicated
CPIO is really this article, isn't it? 129.241.158.188 21:34, 12 October 2005 (UTC)
[edit] Merging
Since the name of the program is cpio, the CPIO article should be merged into this one, not the other way around. 83.71.47.204 22:39, 23 January 2006 (UTC)
- Sure thing. I made the mess, I'll clean it up. I've got a few things to sort out so I'll check back in 24 hours and merge the articles if no one has any objections.
- Another point to note is that the name of the archiving application is "Cpio" whereas it's only the extension of an archive that is lowercase (Even then it might not always be the case.) I'm unsure if a lowercase title is really necessary in this article after merging. The CPIO article refers mostly to the application which starts with a capital, so after the merge, the case "Cpio" is more valid. :-)

[edit] c3po disambig.
Probably, it would be a nice idea to make a disambiguation page for C3po :) It really will... --Yuriy
[edit] 8GB Limit
Curious, does cpio still have the 8GB limit? I have made some fairly large archives that I believe exdeeded 8GB.
