how to add new line at the end with awk

Question

I was searching and trying a lot of different approaches, but non of them really did what I need. Hopefully it was not asked million times before.

I have this alias in my bashrc:

alias temp='awk '\''{ printf ("%0.1f",$1/1000); }'\'' < /sys/devices/platform/sunxi-i2c.0/i2c-0/0-0034/temp1_input'

output of it is:

measure@remote ~ $ temp
10.6measure@remote ~ $

what I'm trying to achieve is ouput like this:

measure@remote ~ $ temp
10.6
measure@remote ~ $

Replace

"%0.1f"

with

"%0.1f\n"

Generic answer to how to add new line at the end with awk would be:

$ awk '... END{print "\n"}'  # or print ORS

@EdMorton I stand corrected. I'll leave this unedited for a while for self shaming on not thinking it through before posting (then again, it _adds a new line ..._). – James Brown Jan 27 '18 at 13:18

Never use an alias for substituting a command and especially ones involving nested quotes like this. Just use a function in .bashrc to simplify it

get_ratio() {
    awk '{ printf ("%0.1f\n",$1/1000); }' /sys/devices/platform/sunxi-i2c.0/i2c-0/0-0034/temp1_input
}

and call it from the command line

measure@remote ~ $ source ~/.bashrc
measure@remote ~ $ get_ratio
