Linux Script to compare two folders and copy missing files
Hi,
I need help in shell scripting. If someone can help me, that would be great!
Problem. I want Linux Script to compare two folders and copy missing files.
Description.
I have two directories
/dir1
/dir2
I need to copy all distinct/new/unique/missing files from /dir1 and that does not have a correspondent file in /dir2. Condition is , It should only check files 2 days old specified in File pattern below.
ex:
/dir1 Files.
filetoTest_20120923.tar.gz
filetoTestAndCopy_20120922.tar.gz
filetoRead_20120925 (This file does not have any extension)
filetoTest_20120918.tar.gz
filetoTestAndCopy_20120925.tar.gz
filetoRead_20120927
filetoTestAndCopy_20120927.tar.gz
Now, files in /dir2/
filetoTest_20120923.tar.gz
filetoTestAndCopy_20120922.tar.gz
filetoRead_20120925 (This file does not have any extension)
filetoTest_20120918.tar.gz
Thus, the script should run and copy the files
filetoRead_20120927
filetoTestAndCopy_20120927.tar.gz
from dir1 to dir2. (Two days old)
Thanks in advance for the help.

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/.
