Automate make execution with variable parameter

SEED = $$RANDOM 
INC  = +incdir+../rtl +incdir+../tb +incdir+../test
comp = ncverilog +access+rwc -uvm -coverage all -seed $(SEED) $(INC) ../tb/top.sv  
logs=mkdir logs;mv test_case* ./logs

test1:  
    $(comp) +UVM_VERBOSITY=UVM_MEDIUM +UVM_TESTNAME=test_case_1; 
    mkdir test_case_1_$(SEED);  
    mv cov_work ./test_case_1_$(SEED);  
    mv ncverilog.log NCVERILOG_$(SEED).log  
    mv *.log ./test_case_1_$(SEED)
      $(logs)

Here “SEED” means a random number:

make test1 SEED=23679

I will run the target test1 in terminal likewise. But the problem is here I want to run that target 10 times by using any conditional loops. If i want to run the test1 2nd time again I need to give like this:

make test1 SEED=40244

3rd time:

make test1 SEED=87797

4th time:

make test1 SEED=5489

Likewise, each and every time I need to give the seed value in the terminal. I don’t want it to be like that, if any conditional loops are there to run test1 for 10 times with 10 different seeds that’s reduce a lot of time for me.

Answer

seeds.txt:

Execute make test1 with SEED taken from seeds.txt only once:

cat seeds.txt | while read in; do make test1 SEED=$in; done

Execute make test1 with SEED taken from seeds.txt 10 times:

cat seeds.txt | while read in; do seq 10 | xargs -I -- make test1 SEED=$in; done

You’re welcome.
