bash - How do I get just real time value from 'time' command? -

I will create a script which uses only real time values ​​from time commands, so that I can plot the results. For example time command output

  real 1m0.001s user 1m0.000s sys 0m0.001s  

I want to write Script which outputs

  60.001  

How do I get real time values ​​from the 'time' command in seconds?

according to man time , should do the following:

Edit : time with your path Call:

  $ / Usr / bin / time -f "% e" sleep 5 5.00  

Without the path, this is something like bash With the path being used equal to , it works for me.
