Space as a delimiter

not sure if i'm doing this right i'm new tho this but i'm trying to use a space as a delimiter with the cut command

my code is

size=$( du -k -S -s /home/cmik | cut -d' ' -f1 )

i've also tried -f2 and switching the -d and -f around if that does anything

I see that above command prints the whole record (size and directory name). Not sure why it's not able to print only the size.
But following should work.
Code:
size=$( echo $(du -k -S -s /home/cmik) | cut -d' ' -f1 )

OR
Code:
size=$( du -k -S -s /home/cmik | cut -f1 )

OR
Code:
size=$( du -k -S -s /home/cmik | awk '{print $1}' )

OR
Code:
size=$( du -k -S -s /home/cmik | awk -F " " '{print $1}' )

I think du uses a TAB character between the size and the name so no -d needed on cut

Code:
size=$( du -k -S -s /home/cmik | cut -f1 )
