UPDATED:
I have this awk command I want to nest into a system("") command.
awk ' BEGIN {yr=2016} !/^#/ && NF!=0 { for(i=2;i<=NF;i++) a[i]+=$i } END { for (y=2;y<=NF;y++) print yr++ " - (" a[y] " Loads)" }' vol.dat
so I tried this:
system("awk ' BEGIN {yr=2016} !/^#/ && NF!=0 { for(i=2;i<=NF;i++) a[i]+=$i } END { for (y=2;y<=NF;y++) print yr++ \" - (\" a[y] \" Loads)\" }' vol.dat")
Bash does not like it due to the nesting and I am obviously not escaping the quotes correctly. However I try to escape the characters I can not get it to print with a space.
Here is some sample input, but as I said it is not an awk problem it is an issue with the awk command being nested in double quotes and escape characters:
vol.dat
Jan 0 165 165 228 78
Feb 10 52 149 196 79
Mar 46 186 159 137 182
Output:
2016 (56 Loads)
2017 (403 Loads)
2018 (473 Loads)
2019 (561 Loads)
2020 (339 Loads)
Solved it. See Gnuplot, how to include a space character in key titles? The problem was that I needed to use Enhanced postscript: &{x} to make a space in the title
