That's easier with sed unless you process the file with awk anyhow beforehand in which case you should include the append there. Try
sed '$!s/$/ \&/' file

Hello f_o_555,

Could you please try following and let me know if this helps you.

awk 'FNR==NR{count++;next} FNR<count{print $0 FS "&";next} 1' Input_file Input_file

Hello f_o_555,

Could you please try following and let me know if this helps you.

awk 'BEGIN{print "TEXT A"} {print $1 FS "A"} END{print $2}' Input_file
Thanks,

Assuming that your awk doesn't forget $1 nor NF in the END section, try:awk '{for (i=2; i<=NF; i++) SUM[i]+=$i} END {printf "%s", $1; for (i=2; i<=NF; i++) printf "%s%s", FS, SUM[i]; printf "\n"}'...

NewName has the value " 12". Print it within double quotes:N=$(printf "%*s" 3 $1)
echo $N
12
echo "$N"
12
Please note there's a double quote missing in your assignment...

Hello f_o_555,

I am not sure how you have tried running command with other files, but please make sure about command like first file should have 3 fields and 2nd passed file should have 2 fields...

Hello f_o_555,

Could you please try following and let me know if this helps.

Try alsoawk '{getline X < F1; print $1, X*$2}' F1=file2 file1 | sort -nr -k2

A bit shorter
awk '{out = 0; for(i = 3; i <= NF; i+=2) {out += $(i-1) * $i }; print out}' file

If you are so sure about what you said, below is the code
awk '{out = 0; for(i = 2; i <= NF; i++) {if(i % 2 == 0) {p = $i} else {out = out + (p * $i)}}; print out}' file

Hi

Either this
if test -f "$file_name"
or this:
if [ -f "$file_name" ]

if [ -f "$file_name" ]; then
echo File $file_name Found
else
echo File $file_name Not Found
fi


Alternate one ..

$ [ -f "$file_name" ] && echo "Filename $file_name Found"...

if awk -v A="1.23e+01" -v B="3.21e+02" 'BEGIN { if(A>B) exit 0; exit 1 }'
then
echo "A>B"
else
echo "A<=B"
fi

awk '{print $2}' file1 > file3
fgrep -f file3 file2

Hi f_o_555,

I don't understand your v>6e-31 condition in the 'awk' command. Try if next one works for you:

$ cat file1
BB152 6.279650E+02
AA124 6.279650E+02
$ cat file2
AA124 ...

join -a 2 -e " " -o 1.1 1.2 2.1 2.2 file1 file2

sort the output if that helps i.e. awk '{...}' input_file | sort
or
Try this...

awk '{sum+=$3;a[++j]=$0}END{for(i=1;i<=j;i++){split(a[i],arr);if(arr[3]/sum > val){print a[i]}}}' val="0.016"...

Try this...

awk '{sum+=$3;a[$0]=$3}END{for(i in a){if(a[i]/sum > val){print i}}}' val="0.016" input_file

The product i.e. $3*a[$1] is too small, so .5f will not print anything...

Try this...

awk 'NR==FNR{a[$1]=$2;next} $1 in a{v=$3*a[$1]}v{print $1,$2,v}' file2 file1 > file3
