The $[ ] syntax is rather obsolete these days. If your shell supports it, the more modern COUNT=$((COUNT+1)) is recommended.

sg_sync
SG_SYNC(8) SG3_UTILS SG_SYNC(8)
NAME
sg_sync - send the scsi command synchronize cache
SYNOPSIS
sg_sync [--count=COUNT] [--group=GROUP] [--help] [--immed] [--lba=LBA] [--sync-nv] [--verbose] [--version] DEVICE
DESCRIPTION
Send SYNCHRONIZE CACHE (10) command to DEVICE. This command is defined for SCSI block devices (see SBC-2). If successful this command makes
sure that any blocks whose latest versions are held in (volatile) cache are written to (also termed as "synchronized with") the medium. If
the --sync-nv option is given and the device has a non-volatile cache then any blocks whose latest versions are held in volatile cache are
written to non-volatile cache.
If the LBA and COUNT arguments are both zero (their defaults) then all blocks in the cache are synchronized. If LBA is greater than zero
while COUNT is zero then blocks in the cache whose addresses are from and including LBA to the highest lba on the device are synchronized.
If both LBA and COUNT are non zero then blocks in the cache whose addresses lie in the range LBA to LBA+COUNT-1 inclusive are synchronized
with the medium.
OPTIONS
Arguments to long options are mandatory for short options as well.
-c, --count=COUNT
where COUNT is the number of blocks to synchronize from and including LBA. Default value is 0. When 0 then all blocks in the
(volatile) cache from and including LBA argument to the highest block address are synchronized.
-g, --group=GROUP
where GROUP is the group number which can be between 0 and 31 inclusive. The default value is 0 . Group numbers are used to segre-
gate data collected within the device. This is a new feature in SBC-2 and can probably be ignored for the time being.
-h, --help
output the usage message then exit.
-i, --immed
sets the IMMED bit in the SYNCHRONIZE CACHE command. This instructs the device, if the format of the command is acceptable, to
return a GOOD status immediately rather than wait for the blocks in the (volatile) cache to be synchronized with (i.e. written to)
the medium (or the non-volatile cache).
-l, --lba=LBA
where LBA is the lowest logical block address in the (volatile) cache to synchronize to the medium (or the non-volatile cache).
Default value is 0 .
-s, --sync-nv
synchronize the (volatile) cache with the non-volatile cache. Without this option (or if there is no non-volatile cache in the
device) the synchronization is with the medium.
-v, --verbose
increase the level of verbosity, (i.e. debug output).
-V, --version
print the version string and then exit.
NOTES
Various numeric arguments (e.g. LBA) may include multiplicative suffixes or be given in hexadecimal. See the "NUMERIC ARGUMENTS" section in
the sg3_utils(8) man page.
EXIT STATUS
The exit status of sg_sync is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
