TTLEXEC                ST Programmer's Manual                  TTLEXEC

NAME
     ttlexec - execute hard disk backup

SYNOPSIS
     ttlexec [-acdfinost] path [...path]

DESCRIPTION
     ttlexec does disk backup to floppies by reading the specified
     path name(s) and writing either all files, or all unarchived
     files. It uses a RAMDISK to create an in-memory image of the
     floppy to write, then does a track-by-track copy of the RAMdisk
     image. The only RAMdisks useable are TRDNSS.PRG for normal format
     single sided diskettes, TRDNDS.PRG for double sided normal format
     diskettes, TRDTSS.PRG for "TWISTER" format single sided diskettes,
     and TRDTDS.PRG for "TWISTER" format double sided diskettes.
     Before executing ttlexec, nearly all of the system memory must be
     available.

-a   inhibit setting the ARCHIVE bit on files as they are copied.
     Normally the ARCHIVE bit is set as the files are backed up.

-c # write # copies of each disk. Normally, only one copy of each
     diskette is written.

-d   hold screen after completion. Normally used only when invoked
     from the desktop.

-f   format floppies before writing. Normally floppies are assumed
     to be formatted and ready for writing. They need not be erased
     since ttlexec will over-write any existing data on the disks.
     Only normal format diskettes can be formatted, "TWISTER" disks
     must be pre-formatted.

-i   incremental backup. Copy only the files with the ARCHIVE bit
     reset. Normally, all files are copied.

-n # number the output disks starting with #. Normally output disks
     are numbered beginning with 1.

-o   only files are to be copied. All files in the named path are
     backed up (unless -i is specified), but folders within the named
     path are not backed up.

-s   single sided output disks. Normally output is prepared for
     double sided disks.

-t   write diskettes in "TWISTER" format.

-v   verify output disks. Normally output disks are written, but not
     read back. 

BUGS
     GEMDOS has a significant problem when over 40 folders are accessed
     between system resets. Avoid this by backing up specific path names
     to control the number of folders read and written between resets.
     An error will occur if more than 112 files are written to the root
     directory of the RAMdisk between floppy writes.
