English is not my native language, so i hope i can explain myself properly and you can understand me.
Perhaps may exists another way to get it, but the 'sort' command reads the data with a field separator (space by default). I want to sort the output using the sales amount, and would be the fourth word in most of the lines, but it would be wrong with this line
because the fourth word would be 'Boy', not the amount, so the sorting would fail. I need another field separator regardless of the name and position strings.

truncate
TRUNCATE(1) User Commands TRUNCATE(1)NAME
truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
treat SIZE as number of IO blocks instead of bytes
-r, --reference=RFILE
base size on RFILE
-s, --size=SIZE
set or adjust the file size by SIZE bytes
--help display this help and exit
--version
output version information and exit
The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow-
ers of 1000).
SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round
down to multiple of, '%' round up to multiple of.
