Data extracting and using date from filenames in a loop
HIya,

Having a dumb day whilst writing an archive process in Shell want to extract from the filename the date and archive into tar files based on this, I don't want to use mtime as it may not be the actual file date.

The files are

-rw-rw---- 1 user admin 100 Aug 29 11:10 Jav_Transmission_20080826.dat
-rw-rw---- 1 user admin 100 Aug 29 11:10 Jav_Transmission_20080827.dat
-rw-rw---- 1 user admin 100 Aug 29 11:11 Jav_Transmission_20080828.dat
-rw-rw---- 1 user admin 100 Aug 29 11:11 Jav_Transmission_20080829.dat

so for each of the days in the below dir I want to find a way to sort of

for dates in `ls -l |extract distinct file date in thias directory`

tar -cvf ${dates}.tar *${dates}*.dat
mv ${dates}.tar /arc

done

So of thing, any help gratefully received.

git-tar-tree

GIT-TAR-TREE(1) 						    Git Manual							   GIT-TAR-TREE(1)

NAME

       git-tar-tree - Create a tar archive of the files in the named tree object

SYNOPSIS

       git tar-tree [--remote=<repo>] <tree-ish> [ <base> ]

DESCRIPTION

       THIS COMMAND IS DEPRECATED. Use git archive with --format=tar option instead (and move the <base> argument to --prefix=base/).

       Creates a tar archive containing the tree structure for the named tree. When <base> is specified it is added as a leading path to the files
       in the generated tar archive.

       git tar-tree behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used
       as modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used
       instead. Additionally the commit ID is stored in a global extended pax header. It can be extracted using git get-tar-commit-id.

OPTIONS

       <tree-ish>
	   The tree or commit to produce tar archive for. If it is the object name of a commit object.

       <base>
	   Leading path to the files in the resulting tar archive.

       --remote=<repo>
	   Instead of making a tar archive from local repository, retrieve a tar archive from a remote repository.

CONFIGURATION

       tar.umask
	   This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write
	   bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) for details.

EXAMPLES

       git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)
	   Create a tar archive that contains the contents of the latest commit on the current branch, and extracts it in /var/tmp/junk directory.

       git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz
	   Create a tarball for v1.4.0 release.

       git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz
	   Create a tarball for v1.4.0 release, but without a global extended pax header.

       git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar
	   Get a tarball v1.4.0 from example.com.

       git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar
	   Put everything in the current head's Documentation/ directory into git-1.4.0-docs.tar, with the prefix git-docs/.
