Appendix D – Table of BRU Modes and Options

The following table is a list of the bru modes. See Appendix C, “The BRU Manual Page,” for Full descriptions.
bru mode [control options] [selection options] [files]
MODE
-c create a new archive with specified files
-d find differences between archived files and
current files
-e estimate media requirements for create mode
(media size must be known)
-g print only information from archive header
-gg print only the list of files created during
the -G option (for pre-17.0 archives)
-h print help information
-i inspect archive for consistency and data
integrity
-t list archive table of contents for files
-x extract named files from archive
The following table shows which of the BRU options are valid for each mode. See Appendix C, “The BRU Manual Page,” for Full descriptions.

MODES CONTROL OPTIONS
c,d,e,g,gg,h,i,t,x
*,*, , , , , , , -a Reset file access times after reads.
*,*,*, , , , ,*,* -b bufsize Set archive buffer size to bufsize bytes (scalable).
*,*,*, , , , , , -B Background mode. No interaction with operator
, , , , , , , ,* -C Always chown extracted files to the user’s uid/gid
*,*, , , , , , ,* -D On some systems, provides speedup via double buffering
*, , , , , , , ,* -F No checksum computations or checking (dangerous for backup)
*,*,*,*, *,*,*,*,* -Ib Reads and writes to default fifos.
*,*,*,*, *,*,*,*,* -Il,pathname Write verbosity information to pathname
*,*,*,*, *,*,*,*,* -Iq,fifo Write interaction queries to fifo
*,*,*,*, *,*,*,*,* -Ir,fifo Read interaction replies from fifo
*,*,*, , , ,*, ,* -j Enables a progress output for files larger than 500K
*, , , , , , , , -l Suppress warnings about unresolved links
*, , , , , , , ,* -L string In Create (backup) mode, BRU Labels the archive with a given string from either the given string or from a file (63 character maximum). In Extract (restore) mode, BRU is forced to check the archive label and compare it to the given label. Can be disabled with -QL option.
*, , , , , , , , -m Limit directory expansions to the same mounted filesystem
*, , , , , , , , -N level Use level for compression (default is 3). See – Z
MODES CONTROL OPTIONS
c,d,e,g,gg,h,i,t,x
*, , , , , , , , -O Overwrite archive regardless of OVERWRITEPROTECT and RECYCLEDAYS settings
,*, , , , ,*,*,* -p Pass over archive files by reading rather than seeking.
*, ,*, , , ,*,*,* -Pa Turn off absolute to relative pathname conversion.
*, ,*, , , ,*,*,* -PA Turn on absolute to relative pathname conversion
*, ,*, , , , , , -Pe Turn off expansion of directories.
*, ,*, , , , , , -PE Turn on expansion of directories.
*, ,*, , , , , , -Pf Turn off filter mode (build internal file tree). For stdin input only.
*, ,*, , , , , , -PF Turn on filter mode (do not build internal tree).
*, ,*, , , , , , -Pp Turn off automatic archiving of parent directory nodes
*, ,*, , , , , , -PP Turn on automatic archiving of parent directory nodes
*, , , , , , , , -QH Turns off placing small files into file headers (NOFILESINHDRS=YES)
, , , , , , , ,* -QR Disable SmartRestore
, , , , , , , ,* -QS Forces the translation of symbolic links during the -T translate on restore option
*,*, , , , ,*,*,* -QV Ignore the incorrect volume warning in a multi-volume operation
