dcopy_s5(1M)


dcopy_s5 -- copy s5 file systems for optimal access time

Synopsis

dcopy [-F s5] [generic_options] [-sX] [-an] [-d] [-v] [-ffsize[:isize]] inputfs outputfs

Description

generic_options are options supported by the generic dcopy command.

With no options, dcopy copies files from inputfs compressing directories by removing vacant entries, and spacing consecutive blocks in a file by the optimal rotational gap.

s5-specific options

-F s5
Specifies the s5-FSType. Need not be supplied if the information may be obtained from /etc/vfstab by matching the inputfs device with an entry in the file.

-sX
Supply device information for creating an optimal organization of blocks in a file. X must be of the form cylinder_size:gap_size.

-an
Place the files not accessed in n days after the free blocks of the destination file system If no n is specified then no movement occurs.

-d
Leave order of directory entries as is. The default is to sort the directory based on how recently each entry has been accessed. Entries accessed within the last 24 hours will be placed at the beginning of the directory. All subdirectories will be treated as if they were accessed within the last 24 hours.

-v
Reports how many files were processed and how big the source and destination freelists are.

-f fsize[:isize]
Specify the outputfs file system (fsize) and inode list (isize) sizes in logical blocks. If the suboption (or :isize) is not given, the values from inputfs are used.

dcopy catches interrupts and quits and reports on its progress. To terminate dcopy, send a quit signal followed by an interrupt or quit.
