Full Discussion: Wait and continue if directory stays same size

Please don't ask the same question in two threads! It is almost impossible for people trying to help you to follow one discussion being held in two places!

As I said in post #40 in the thread titled Script to tar/rsync/rm multiple folder names:
Quote:
The size of a directory tells you very little about whether or not files in that directory are growing, and (if any files have ever been removed from a directory) even if a new file is created in a directory, its size might not change.

It would be much better if you would create a hidden directory under /to_be_archived (such as /to_be_archived/.in_progress/project), move everything into that directory, and then after that project directory contains everything you want to archive, issue the command:
Code:
mv /to_be_archived/.in_progress/project /to_be_archived/project

which will be an atomic operation. Your existing script won't see the hidden directory so it won't see .in_progress/project until it is ready to process after it has been moved up.

bf_tar

BF_TAR(1)						    Bogofilter Reference Manual 						 BF_TAR(1)

NAME

       bf_tar - shell script to write a tar file of a bogofilter directory to stdout

SYNOPSIS

       bf_tar [-r] [-R] bogofilter_directory

DESCRIPTION

       bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
       EXAMPLES below).

OPTIONS

       The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
       files.

       The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
       is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.

EXIT STATUS

       The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.

EXAMPLES

       o   bf_tar ~/.bogofilter > outfile.tar

	   Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.

       o   bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz

	   Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.

       o   bf_tar `pwd`/mydirectory > outfile.tar

	   Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.

NOTES

       This script is meant for use with Berkeley DB based bogofilter versions.

       This script requires a SUSv2 compliant pax utility.

       This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
       that /usr/xpg4/bin/sh can be used.
