scottn is right


Code:
[root@localhost ~]# df -h . |tail -1 |cut -d'%' -f1 |awk '{print $NF}'
57

[root@localhost ~]# ssh localhost "df -h . |tail -1 |cut -d'%' -f1 |awk '{print $NF}'"
root@localhost's password: 
/dev/sda5              29G   16G   13G  57

[root@localhost ~]# ssh localhost "df -h . |tail -1 |cut -d'%' -f1 |awk '{print \$NF}'"
root@localhost's password: 
57

@ygemici
your solution wont work either, because of the unmasked $ in awk
Code:
[root@localhost ~]# ssh localhost << EOF
> df -h . |tail -1 |cut -d'%' -f1 |awk '{print $4}'
> EOF
Pseudo-terminal will not be allocated because stdin is not a terminal.
root@localhost's password: 
/dev/sda5              29G   16G   13G  57
