Shell Programming and Scripting

Hi all,
I am using following command:

Code:

perl program.pl input.txt output.txt  CUTOFF 3 > groups_3.txt

containing program.pl, two files (input.txt, output.txt) and getting output in groups_3.txt:

But, I wish to have 30 files corresponding to each CUTOFF ranging from 0 to 30 using the same program.pl, two files (input.txt, output.txt), because with each value of CUTOFF I will get different number of groups in each output file. In other words, I want to call program.pl using input.txt output.txt with different CUTOFF.

Thanks

Try the following from bash

Code:

for VAL in {0..30}
do
    echo "Producing for CUTOFF: $VAL"
    perl program.pl input.txt output.txt  CUTOFF $VAL > groups_$VAL.txt
done

or

Code:

for VAL in `seq 0 30`
do
    echo "Producing for CUTOFF: $VAL"
    perl program.pl input.txt output.txt CUTOFF $VAL > groups_$VAL.txt
done
