why is my awk command printing on a newline??????

I am creating a table as follows

Code:

pdb  uniprot  #ligands  Energy  

---------------------------------------

2h7l  P0A5Y6  500

-32.893

3e37  Q8K2I1  501

-38.5512

1bcd  P00918  505

-26.5727

the negative number is an average of a column of numbers from a separate file. my code is as follows

Code:

#!bin/bash







printf "pdb  uniprot  #ligands  Energy  \n"

echo '---------------------------------------'





while read pdbs

do

        cd rn$pdbs

        while read uni

        do

                printf $pdbs

                printf "  "

                cd run.$uni

                printf $uni

                printf "  "

                cd 1.A

                for a in *.gz 

                do

                        gzip -d $a

                done

        

                        grep -i 'remark c' test.eel1 >        out.txt

                        wc -l out.txt > a

                        awk '{print $1}' a

                        awk '{ total +=$5; count++ } END { printf total/count }' out.txt # creating new line??? 

                

                printf "\n"

                cd ../..

        done < uni_codes.txt

        

        



cd ..







done < $1

I have tried print & printf statements. I have also tried saving the output of the awk command and cat the awk output file. I also tried adding a <| tr -d '\n'> after the awk command, which didn't work Any ideas? my table doesn't really make sense with the numbers down there. Thanks!!!

figured it out, I needed a printf in the 1st awk command!

I just made a post in your other thread about the use of printf. Please learn how to use it correctly.

Also note that the printf in awk has a slightly different syntax from bash's version (arguments are separated by commas), and is capable of doing more (particularly when working with numbers, due to the full floating-point arithmetic engine). awk's print command is pretty much equal to bash's echo.

Speaking of which, I should've mentioned before, you can also use echo -n in bash to print a simple string without a newline (equivalent to "printf '%s'").

Edit: see here for details on gawk's version of printf.
