Can't create Wordlist in Backtrack (crunch)

Question

I am unable to create a wordlist in Backtrack by using the following command

./crunch 6 12 -f charset.lst mixalpha -o wordlist.txt

gives error

chunk1: fprintf failed = 28
The problem is = No space left on device

What could be the possible reason for failure?

Answer 1

No free space left for crunch to print the entire word list
