Is there an easy way to concatenate the result of two linux commands, in one line? (i.e without using variables)



I pull the local outdoor temperature from a nearby weather station. The result today is:
5.2
I simply want to add the units, so result should look like this:
5.2°C



An example command, that almost gives me what I want is:
wget -q -O- "http://meteocentre.com/montreal/home_e.html" | grep -oP '(?<=Tn= ).*(?=&deg)' ; printf "°Cn"






bash awk sed grep tr

          Or do it inside-out:



          printf "%s°Cn" "$(wget -q -O- "http://meteocentre.com/montreal/home_e.html" | grep -oP '(?<=Tn= ).*(?=&deg)')"


          So that the results from wget...|grep... are collected as a command-substitution and inserted into the %s in the printf.

            echo, for example, just prints all the arguments you give it. You can use command substitution to turn the output of a command into a string.



            echo $(wget -q -O- "http://meteocentre.com/montreal/home_e.html" | grep -oP '(?<=Tn= ).*(?=&deg)') °C

              Delete the carriage return at the end of wget’s output:



              wget -q -O- "http://meteocentre.com/montreal/home_e.html" | grep -oP '(?<=Tn= ).*(?=&deg)' | tr -d 'n' ; printf "°Cn"
