#for i in {1..9}; do for j in $(seq 1 $i); do echo -ne $i×$j=$((i*j))\\t;done; echo;done
Valor de PI
#seq -f '4/%g' 1 2 99999 | paste -sd-+ | bc -l
#for i in {1..9}; do for j in $(seq 1 $i); do echo -ne $i×$j=$((i*j))\\t;done; echo;done
Valor de PI
#seq -f '4/%g' 1 2 99999 | paste -sd-+ | bc -l
Este comando es genial
figlet
#apt-get install figlet
#figlet moleculax
#apt-get install cowsay
