varible hosname and time stamp

What steps will reproduce the problem?
1. sh run | redirect ftp://user:password@10.1.1.2/$h-$t.cfg
2. sh vlan | redirect ftp://user:password@10.1.1.2/$h-$t_vlan.txt
3. sh ip int brief | redirect ftp://user:password@10.1.1.2/$h-$t_int.txt

What is the expected output? What do you see instead?
I would like to use above cmd using Command feature in Supper Putty for 
Hundrads of Switches, but file name should save with hostname and time stamp 
format. But I am seeing only variable symbols.

What version of the product are you using? On what operating system?
Version 1.4.0.6  on Windows 7

Please provide any additional information below.
Please advise how to save the backup file (some variable sybol) with eash 
hostname on Supper Putty Command Feature
