Which simulator? Why not read its documentaion? With VCS it is:

vcs dff.v and dff_tb.v -R

MTI:

vlog dff.v and dff_tb.v
vsim dff_tb

Better read the tool doc.

vlib,vlog,vsim commands.But i want to know how do we can use them in case

First, create library directory:

vlib work

Second, compile all verilog files:

vlog [-y lib_dir] [-v lib_file] source_file(s) (run "vlog -help" for
more options)

Third, run simulation.

Interactive sim: --------------------
vsim top_level_module(s)

Opens Modelsim gui.

From the command line, run commands such as:
add wave -r * (to add all signals to waveform window)

run -all (run time controled from verilog with $stop command) or:
run 1000 (specify run time from the command line)

Also, it is useful to write the number of useful tcl procedures into
the "do" file and source this file to the modelsim:
vsim -do "run.do" top_level_module(s)

batch sim: ------------------------
vsim -c -do "run -all; quit -f" top_level_module(s)
