Build

1. to build run make .
2. to install it run make install.

Listing Processes:

./ps | head -n5

USER     PID    PPID   CPU     ELAPSED          TTY    TIME   COMMAND
root     7      1      0.000   29m26.0628125s   tty1   0s     /init

abdfnx   317    8      0.290   28m44.0652407s   tty1   5s     zsh

Display Different Format Descriptors:

./ps -format "pid, user, group, tty" | head -n5

PID    USER     GROUP    TTY
1      root     root     tty1
