# After wondering how commands like curl showed a progress bar, with the very big help of
# Google, I decided to write a shell script to show a progress bar
#
# Having not done much shell scripting, I learned a few (very likely quite obvious) things:
#   * It looks much nicer to create the string to echo in a variable, then echo it.  If I echo'ed
#     each part of the string instead of concatenating it with the rest of the string, the cursor
#     jumped around quite a bit.
#   * 'let x=x+1' is a lot faster than 'x=`expr $x + 1`' (I have a feeling this is probably because
#     let is implemented directly in bash, instead of a separate command)
