           Summary: flag to suppress link_stat error messages
           Product: rsync
           Version: 3.1.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: mij at bitchx.it
         QAContact: rsync-qa at samba.org


rsync complains about file arguments not existing.

For example, running this command to archive a selected set of files:

rsync -aq --remove-from-source --remove-source-files /var/log/messages*bz2
/backup/maillog*bz2 /backup/auth.log*bz2 backupserver::myname/

will issue the following errors if any of the given patters has no match:

rsync: link_stat "/var/log/messages*bz2" failed: No such file or directory (2)
rsync: link_stat "/backups/maillog*bz2" failed: No such file or directory (2)
...

One particular application of commands similar to this is to periodically save
archives to a central backup server via cron. This causes cron to periodically
mail admins with the above errors. The option to divert this to /dev/null is
dangerous, as it would lose other error messages which ARE actually useful,
such as failures to reach the backup server.

A command line argument such as --ignore-missing-files that avods this type of
errors (link_stat) would do great.
