Search file A for a list of strings located in file B and append the value associated with that string to the end of the line in file A

This is a bit complicated, well I think it is..

I have two files, File A and file B

File A contains delay information for a pin and is in the following format

AD22 15484
AB22 9485
AD23 10945

File B contains a component declaration that needs this information added to it and is in the format:

'DXN_0':
PIN_NUMBER='(AD22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
'DXP_0':
PIN_NUMBER='(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,AD23,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
'VREFN_0':
PIN_NUMBER='(AB22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';

So what I am trying to achieve is the following output

'DXN_0':
PIN_NUMBER='(AD22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='15484';
'DXP_0':
PIN_NUMBER='(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,AD23,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='10945';
'VREFN_0':
PIN_NUMBER='(AB22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='9485';

There is no order to the pin numbers in file A or B

So I'm assuming the following needs to happen

I'm assuming it will be a combination of sed and awk commands and I'm currently trying to work it out but think this is beyond my knowledge. Many thanks in advance as I know it's complicated..

FINAL Script for my application, A big thank you to all that helped..

# ! /usr/bin/sh

# script created by Adam with a LOT of help from users on stackoverflow

# must pass $1 file (package file from Xilinx)
# must pass $2 file (chips.prt file from the PCB design office)

# remove these temp files, throws error if not present tho, whoops!!
rm DELAYS.txt CHIP.txt OUTPUT.txt

# BELOW::create temp files for the code thanks to Glastis@stackoverflow https://stackoverflow.com/users/5101968/glastis I now know how to do this
DELAYS=`mktemp DELAYS.txt`
CHIP=`mktemp CHIP.txt`
OUTPUT=`mktemp OUTPUT.txt`

# BELOW::grep input file 1 (pkg file from Xilinx) for lines containing a delay in the form of n.n and use TAIL to remove something (can't remember), sed to remove blanks and replace with single space, sed to remove space before \n, use awk to print columns 3,9,10 and feed into awk again to calculate delay provided by fedorqui@stackoverflow https://stackoverflow.com/users/1983854/fedorqui 

# In awk, NF refers to the number of fields on the current line. Since $n refers to the field number n, with $(NF-1) we refer to the penultimate field.
# {...}1 do stuff and then print the resulting line. 1 evaluates as True and anything True triggers awk to perform its default action, which is to print the current line.
# $(NF-1) + $NF)/2 * 141 perform the calculation: `(penultimate + last) / 2 * 141
# {$(NF-1)=sprintf( ... ) assign the result of the previous calculation to the penultimate field. Using sprintf with %.0f we make sure the rounding is performed, as described above.
# {...; NF--} once the calculation is done, we have its result in the penultimate field. To remove the last column, we just say "hey, decrease the number of fields" so that the last one gets "removed".

grep -E -0 '[0-9]\.[0-9]' $1 | tail -n +2 | sed -e 's/[[:blank:]]\+/ /g' -e 's/\s\n/\n/g' | awk '{print ","$3",",$9,$10}' | awk '{$(NF-1)=sprintf("%.0f", ($(NF-1) + $NF)/2 * 169); NF--}1' >> $DELAYS

# remove blanks in part file and add additional commas (,) so that the following awk command works properly
cat $2 | sed -e "s/[[:blank:]]\+//" -e "s/(/(,/g" -e 's/)/,)/g' >> $CHIP

# this awk command is provided by karakfa@stackoverflow https://stackoverflow.com/users/1435869/karakfa Explanation: scan the first file for key/value pairs. For each line in the second data file print the line, for any matching key print value of the key in the requested format. Single quotes in awk is little tricky, setting a q variable is one way of handling it. https://stackoverflow.com/questions/32458680/search-file-a-for-a-list-of-strings-located-in-file-b-and-append-the-value-assoc
awk -vq="'" 'NR==FNR{a[$1]=$2;next} {print; for(k in a) if(match($0,k)) {print "PIN_DELAY=" q a[k] q ";"; next}}' $DELAYS $CHIP >> $OUTPUT

# remove the additional commas (,) added in earlier before ) and after ( and you are done..
cat $OUTPUT | sed -e 's/(,/(/g' -e 's/,)/)/g' >> chipsd.prt

awk to the rescue...

$ awk -vq="'" 'NR==FNR{a[$1]=$2;next} {print; for(k in a) if(match($0,k)) {print "PIN_DELAY=" q a[k] q ";"; next}}' keys data 

'DXN_0':
PIN_NUMBER='(AD22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='15484';
'DXP_0':
PIN_NUMBER='(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,AD23,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='10945';
'VREFN_0':
PIN_NUMBER='(AB22,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)';
PIN_DELAY='9485';

Explanation: scan the first file for key/value pairs. For each line in the second data file print the line, for any matching key print value of the key in the requested format. Single quotes in awk is little tricky, setting a q variable is one way of handling it.

FILE2=`cat file2`
FILE1=`cat file1`
TMPFILE=`mktemp XXXXXXXX.tmp`
FLAG=0
for line in $FILE1;do
    echo $line >> $TMPFILE 
    for line2 in $FILE2;do
    if [ $FLAG == 1 ];then
        echo -e "PIN_DELAY='$(echo $line2 | awk -F " " '{print $1}')'" >> $TMPFILE
        FLAG=0
    elif [ "`echo $line | grep $(echo $line2 | awk -F " " '{print $1}')`" != "" ];then
        FLAG=1
    fi
    done
done
mv $TMPFILE file1

Works for me, you can also add a trap for remove tmp file if user send sigint.
