# Your trying to pass "$1" to awk, right?
# 
# If so, you need single quotes I think
# 
# awk '{ print tolower($1) }' /tmp/new_users.txt
# 
# or try a '\' in front of the $ sign, like
# 
# awk "{ print tolower(\$1) }" /tmp/new_users.txt
# 
# And finally, you talk about lines.  IIRC $0 is the entire 
# line, not $1.  $1 is just the first field.
#  
# FYI: You can also do this with tr I believe, and tr is easier 
# to use for simple tasks.
