timekeeper

timekeeper is an elementary shell. It accepts a set of commands, executes them, and prints out usage statistics.

Execution and statistics

An example usage is

./timekeeper echo Hello, World

With likely output

Process with id: 86159 created for the command: echo
Hello World
The command "echo" terminated with returned status code = 0
real: 0.00 s, user: 0.00 s, system: 0.00 s, context switch: 0

where real, user, system, and context switch stands for the wall-clock time, user time, system time, and number of context switches, respectively.

Pipe support

timekeeper supports pipes. To be noted, the default pipe symbol is !, instead of |.

An example usage:

./timekeeper echo Hello ! python3 dummy.py World

With likely output

Process with id: 2771 created for the command: echo
Process with id: 2772 created for the command: python3
Hello World
The command "echo" terminated with returned status code = 0
real: 0.00 s, user: 0.00 s, system: 0.00 s, context switch: 0
The command "echo" terminated with returned status code = 0
real: 0.22 s, user: 0.00 s, system: 0.00 s, context switch: 0
