Need to create files that represent what the local updates directory would contain after the #** updates were applied, then input these files to Section 8 of SyncDirs10.0 ('synchronise remote backups'). #** The updated local files are needed in two stages: #** 1. After the updates have been downloaded to the local updates directory, and #** 2. After the obsolete files have been deleted from the local updates directory. #** In Stage 1, files in ftp.fil. need to be added to local.files., with the result left in local.files3.. #** In Stage 2, the files in local.remove. need to be removed from local.files3., with the result placed in local.files4. #** #** The files are created as local.files3.delta and local.files4.delta (etc) which are not overwritten by SyncDirs10.0, and whose #** 'sync remote backups' sections are pointed, in Testing, to local.files4. rather than to local.files.. #** This script creates the required local.files3. and local.files4. files. #** #** Method: Calculate two different versions of local.files. to suit these two different stages. #** Stage 1: The local files remaining after an update has occurred will be equal to: #** local.files. + ftp.fil. (output saved in local.files3.) #** Adding ftp.fil. files can be achieved by using the 'cat' command. #** Stage 2: The local files remaining after the obsolete files have been deleted will be equal to: #** local.files3. - local.remove. (output saved in local.files4.) #** This calculation can be achieved by 'comm -23 local.files3. local.remove.' #** (ie, suppress files unique to file2, and common to both. This leaves files unique to local.files3.) #** #** This script takes a command line argument of '1' or '2' to pick which stage to execute #** #** Note: the 'local.files3.' files are an internal mechanism to this script. Creating these is an intermediate step #** to creating the 'local.files4.' files, which are used in both SyncDirs10.0 and SyncDirs10.0-Test. #**-------------------------------------------------------------------------------------------------------------- # This first declaration is the only one needing user customisation # It needs to match the declaration in SyncDirs10.0 applicable to Testing mode.
