Top Forums Shell Programming and Scripting awk to match file1 and extract specific tag values Post 303028307 by MadeInGermany on Friday 4th of January 2019 04:42:44 AM

I think you want a lookup table from file1: $1 is the lookup key and $2 the returned value.
Code:
# in file 1 store the $2 values in s[$1] (s[] indexed by $1)
FNR==NR {
  s[$1]=$2
  next
}

Now you can test existence with (key in s) or get the value with s[key] or loop through the keys with for (key in s).

I think the following captures the wanted values in file2:
Code:
{
  match($8,/'normalizedPos':'([^']+)'/, pos)  # extract value after : into pos[]
  match((";" $8),/;(AF=[^;]+).*;(FDP=[^;]+)/, info) # extract values after AF= and FDP= into info[]
  match($8,/'gene':'([^']+)'/,gene) # extract the value after gene into gene[]
  print "pos[1]="pos[1], "info[1]="info[1], "info[2]="info[2], "gene[1]="gene[1]
}

Note1: the target array as 3rd argument is an extension in GNU-awk. (Maybe you want to consider perl? Then it works on all platforms that have perl.)
Note2: for a most exact string match use a "border character". I have even prepended a ";" to the input string for match() in order to ensure it exists even at the beginning.
