- NAME:
- compare - compare the CRCs of files as calculated by FILECRC
-
- SYNOPSIS:
- compare [options] [old_crc_file [new_crc_file]]
-
- DESCRIPTION:
- COMPARE reads the two CRC files, records differences in several
- files, and displays suspicious differences on the screen. The
- default input files are CHECK$$$.CRC and CHECK$$$.NEW.
-
- The output files are:
-
- FILES$$$.DEL files that were deleted between the two checks
- FILES$$$.NEW files that were added between the two checks
- FILES$$$.UPD files that were changed, where the file creation
- date was also changed.
- FILES$$$.MOD files improperly modified (file contents changed,
- but creation date unchanged)
-
- If input files were not specified on the command line, COMPARE
- renames its input files as follows:
-
- CHECK$$$.CRC to CHECK$$$.OLD
- CHECK$$$.NEW to CHECK$$$.CRC
-
- OPTIONS:
- The option can appear anywhere on the command line.
-
- -c Conservative checking: report changes to "hidden",
- "system", and "read-only" files to the screen. (This
- switch is normally included on the command line of
- FILECRC and passed on to COMPARE.) When this option is set,
- COMPARE checks the attributes as recorded in the OLDER input
- file.
- -u user customizing - reset file names
-
- IMPLEMENTATION NOTES:
- The names of this program and its input files should be
- customized by each user, either in the source code or at run
- time. See FILECRC.DOC for a discussion.
