Cut command not returning correct output

Scenario

I am trying to use cut command to get the 4th field from a file that has the redirected output of a df command. But it's only cutting and returning the 1st field for some reason.

df -kh -B 1g /ws/abc-Location03 > file1.txt
cut -d" " -f4 file1.txt

Output of my df command

Filesystem           1G-blocks      Used Available Use% Mounted on
abc5-xyz04c:/root_vdm_6/t2local24/abc-Location03
                       500       408        93  82% /ws/abc-Location03

Output of my cut command

abc5-xyz04c:/root_vdm_6/t2local24/abc-Location03

Basically, it's cutting just the 1st field and returning it, instead of the 4th field. I 'd like to know what it is I'm doing wrong.

For this, and many other similar problems, the shortest solution might be to use cuts ("cut on steroids") which tries to fix most pain-points of cut.

Example:

$ df -kh -B 1g / | cuts 3

Because you're delimiting on whitespace and not repeated whitespace, your columns are messed up. Try this:

df -kh -B 1g | tr -s ' ' | cut -d ' ' -f 4

The tr turns all repeated spaces into single spaces, so you can cut them as you please.

You can use awk instead:

df -kh -B 1g /ws/abc-Location03 | awk '{print $4}'
