It's the first time I've read a file (line-by-bloody-line) and would like to know if I can improve this script ?

Hello,
I extracted a list of files in a directory with the command ls . However this is not my computer, so the ls functionality has been revamped so that it gives the filesizes in front like this :

Gents,
Is there the possibility to improve this script to be able to have same output information.
I did this script, but I believe there is a very short code to get same output
here my script

I have "inherited" a OmniOS (illumos based) server.
I noticed rsync is significantly slower in respect to my reference, FreeBSD 12-CURRENT, running on exactly same hardware.
Using same hardware, same command with same source and target disks, OmniOS r151026 gives:

thin_metadata_size
THIN_METADATA_SIZE(8) System Manager's Manual THIN_METADATA_SIZE(8)NAME
thin_metadata_size - thin provisioning metadata device/file size calculator.
SYNOPSIS
thin_metadata_size [options]
DESCRIPTION
thin_metadata_size calculates the size of the thin provisioning metadata based on the block size of the thin provisioned devices, the size
of the thin provisioning pool and the maximum number of all thin prisioned devices and snapshots. Because thin provisioning pools are
holding widely variable contents, this tool is needed to provide sensible initial default size.
-b, --block-size BLOCKSIZE[bskKmMgGtTpPeEzZyY]
Block size of thin provisioned devices in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors with-
out a block size unit specifier. Size/number option arguments can be followed by unit specifiers in short one character and long
form (eg. -b1m or -b1megabytes).
-s, --pool-size POOLSIZE[bskKmMgGtTpPeEzZyY]
Thin provisioning pool size in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors without a pool
size unit specifier.
-m, --max-thins #[bskKmMgGtTpPeEzZyY]
Maximum sum of all thin provisioned devices and snapshots. Unit identifier supported to allow for convenient entry of large quanti-
ties, eg. 1000000 = 1M. Default is absolute quantity without a number unit specifier.
-u, --unit {bskKmMgGtTpPeEzZyY}
Output unit specifier in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors without an output unit
specifier.
-n, --numeric-only [short|long]
Limit output to just the size number with the optional unit specifier character/string.
-h, --help
Print help and exit.
-V, --version
Output version information and exit.
EXAMPLES
Calculates the thin provisioning metadata device size for block size 64 kilobytes, pool size 1 terabytes and maximum number of thin provi-
sioned devices and snapshots of 1000 in units of sectors with long output:
thin_metadata_size -b64k -s1t -m1000
Or (using the long options instead) for block size 1 gigabyte, pool size 1 petabytes and maximum number of thin provisioned devices and
snapshots of 1 million with numeric only output in units of gigabytes:
thin_metadata_size --block-size=1g --pool-size=1p --max-thins=1M --unit=g --numeric-only
Same as before (1g,1p,1M,numeric-only) but with unit specifier character appended:
thin_metadata_size --block-size=1giga --pool-size=1petabytes --max-thins=1mebi --unit=g --numeric-only=short
Or with unit specifier string appended:
thin_metadata_size --block-size=1giga --pool-size=1petabytes --max-thins=1mebi --unit=g -nlong
DIAGNOSTICS
thin_metadata_size returns an exit code of 0 for success or 1 for error.
