Update la update:
sau
for i in `seq 99999`; do : ; done
sau
for ((i=0;i<99999;i++)); do : ; done etc.
unde `:' e treaba utila :-)
de preferat prima (pare-se):
[teo@teo teo]$ cat z1
for i in `seq 10000`; do : ;done
[teo@teo teo]$ time bash z1

[teo@teo teo]$ cat z2
for((i=0;i<10000;i++)); do : ;done
[teo@teo teo]$ time bash z2
