Trying to get 5th field from ls -l output
Bash Shell/Oracle Linux 6.4

Following is an ls -lh output. Files which are equal to or higher than 1Gigabytes will displayed with G in the 5th column of the output.
I am trying to find all files which are equal to or higher than 1G

File sizes are shown in the 5th column. So, I tried
Code:
cut -d' ' -f5

. But it returned blank lines, so I think it may be counting each individual space as a field when there is more than one space together


Code:
ls -lrth *.dmp | cut -d' ' -f5
