# shell scripts can have the file extension of `.sh` but it can
# be more useful to leave it without any extension. instead,
# just put the shebang `#!/bin/bash` at the first one.
# plus, use `chmod +x` to make this script executable.
#
# also, apparently, this convention called shebang is not used
# on windows. `.sh` convention is used in windows. since i'm using
# fedora, i'm going to stick to the shebang convention.

# For my Calc II midterm exam, I needed a proctor service.
# So, I was filling out the Examination Proctor Agreement form,
# which was a pdf. However, okular, the default pdf viewer for
# Fedora happens to have a not-so-perfect annotation functionality.
# The annotations I make in okular would not be visible in any
# other software than okular itself. So, I tried to find

# *cut* command
# This command is useful for filtering data.
# `who | cut -c 1-8' outputs the first eight characters.
# 'who | cut -d' ' -f1,2' sets the delimiter as ' ' and
# outputs the first and second columns.
# *sort* command
# Example: 'who | cut -d' ' -f2 | sort -r' outputs
# the data in the reversed order.
# *uniq* command
# Example: 'who | cut -d' ' -f1 | uniq' removes
# all the dulplicates and outputs only the unique data.
Codes should describe what they do themselves.
Comments, in the other hand, should describe
