# Case 1.
# You can use sgrep to escape # comment out or blank lines
alias sgrep='egrep -v "^\s*(#|$)" --color=auto'

# Case 2.
# You can use cgrep to separate from pure comment and default option.
# For basically default options, there is no white spaces between # and the sentence.
# ex) in my opinion
# This is a pure comment blablabla
#this_is=default_option
