Question

What am I doing wrong in this for-loop? I have the variable $gGID which contain some numbers. I have another that uses the top number of the list which is the $ONEGID variable. I want to use $ONEGID be matched against the list in $gGID and if a match do something else continue.

echo $ONEGID

116899029375914044550 

I collect whats in $gGID with

gGID=$(curl -A 'Mozilla/4.0' --silent "https://www.google.com/search?q=$Daniel%20Sandman%20plus.google.com" | grep -P -o '(?<=plus.google.com/)[^az/u]+(?=/)')

This is what $gGID gives me..

echo $gGID

116899029375914044550
116899029375914044550
116899029375914044550
108176814619778619437
108176814619778619437
108176814619778619437
105237212888595777019
105237212888595777019
105237212888595777019

This is the for-loop I use to match it.

for USERS in $gGID; do
    if [ "$USERS" = "$ONEGID" ]; then
        echo "More than one match"
    else
        echo "Just one match"
    fi
done

I have tried in multiple ways and not figured it out. I don’t see what I am doing wrong. Could it be that the variable I stored in $gGID count as a single number and that is why?

Not certain what you mean, why would you echo “just one match” when it does not match? Anyway, is this what you mean?

#!/bin/bash

ONEGID=116899029375914044550  

gGID=\
"116899029375914044550 
116899029375914044550 
116899029375914044550 
108176814619778619437 
108176814619778619437 
108176814619778619437 
105237212888595777019 
105237212888595777019 
105237212888595777019"

matches=0

for USERS in $gGID; do 
    if [[ $USERS == $ONEGID ]]
    then 
        (( matches++ ))
    fi 
done 

if (( matches == 0 ))
then
    echo "no matches"
elif ((matches == 1 ))
then
    echo "Just one match"
else
    echo "$matches matches"
    echo "more than one match"
fi

(Tested before the question was changed to include curl – works with the curl as well)
