[Adel ESSAFI]

Hello,
I have  followed the man page of  time commande to put a certain output
format.
However, time command does not recognise -f  option.

Could you help please.



[adel at localhost generateInstance]$ time -f "%e" ls
bash: -f: command not found

real    0m0.001s
user    0m0.000s
sys    0m0.000s
[adel at localhost generateInstance]$
