Scripting
A pattern in many scripting languages is to delimit a line comment with #. Support for a block comment varies. Notable languages include: Bash, Raku, Ruby, Perl, PowerShell, Python and R.
An example in R:
# This is a comment
print("This is not a comment") # This is another comment
Block in Ruby
A block comment is delimited by =begin and =end that start a line. For example:
puts "not a comment"
# this is a comment
puts "not a comment"
=begin
whatever goes in these lines
is just for the human reader
=end
puts "not a comment"
