Dot and redirected output syntax in a tar command
Hi All,

Please could anyone advise what the purpose of the dot syntax in the following command means:
Code:
tar -cvf ${WORKING_BACKUP_ROOT}/${TAR_ARCHIVE_FILE} . >/${BACKUP_ROOT}/${ARCHIVE_LOG}

Many thanks

. represents the contents of current directory .
The above commandline creates a tar named ${WORKING_BACKUP_ROOT}/${TAR_ARCHIVE_FILE} containg the elements of current directory .

A relevant point is that the "tar" archive of . should contain relative paths not absolute paths (not all versions of "tar" are the same).
You can check the the paths in the archive with tar -tvf filename.tar .
