I was just about to post that I was not looking for the above code. I have used this, and it collapses return keys and other useful characters.
I only want to reduce spaces beyond a single space to a single space using awk.
Sorry for the runaround.
No worries . Another option may be to just adjust the field separator:
or perhaps a tiny tiny bit more efficient:
But what if you have a space and a TAB together? Do you leave the space or delete it?

How do i split a variable of numbers with spaces... for example
echo "100 100 100 100" > temp.txt
as the values can always change in temp.txt, i think it will be feasible to split the numbers in accordance to column.

concat
concat(1T) Tcl Built-In Commands concat(1T)__________________________________________________________________________________________________________________________________________________NAME
concat - Join lists together
SYNOPSIS
concat ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all
the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args
are supplied, the result is an empty string.
EXAMPLES
Although concat will concatenate lists (so the command:
concat a b {c d e} {f {g h}}
will return "a b c d e f {g h}" as its result), it will also concatenate things that are not lists, and hence the command:
concat " a b {c " d " e} f"
will return "a b {c d e} f" as its result.
Note that the concatenation does not remove spaces from the middle of its arguments, so the command:
concat "a b c" { d e f }
will return "a b c d e f" (i.e. with three spaces between the a, the b and the c).
