it should still fix some issue Misquoted problem in your script. You have an additional quoting at top in glob and missing a quote in echo.
Have it this way:
for f in *
do
    echo "$f"
    if [[ $f == *"txt" ]]
    then
        echo "yes"
    else
        echo "no"
    fi
done

Does that help I have the following in MATLAB: , seems to be working perfectly fine on Mac OS X:
if [ ${line[i]} == '{' ];
> then
> echo "tes"
> fi
tes

Bash 'if' statement in 'for' loop in an 'if' statement

With these it helps I just can't get the code below to work. , The if statement needs to be inside the loop.
for i in $(seq $first $last)
do 
    ping -c 1 ${ip[0]}.${ip[1]}.${ip[2]}.$i > /dev/null
    if [ $? -eq 0 ]; then
        echo "${ip[0]}.${ip[1]}.${ip[2]}.$i is up"
    else
        echo "${ip[0]}.${ip[1]}.${ip[2]}.$i is down"
    fi
done

How do I implement an IF statement into a while loop, and keep while loop running indefinitely? (Bash)

this will help You can take advantage of the fact that you can pipe directly to another command that contains an if statement.
while true; do
  /path/to/file | grep -i "string" | wc -l | {
    read count
    if [[ $count -gt 100 ]]; then
      send_email
    fi
    echo "$count"
  }
done

What is wrong with the following bash statement that has a while loop and a if statement

Hope this helps It would help if you had an example file so we can determine what the filter criteria are. Based on the idea that there are other entries in other_live_photos.csv which do not contain the string live_photos:
while read line 
do 
 livePhotos=$(grep live_photos $line)
 cp $livePhotos other_live_photos 
done < other_live_photos.csv
while read line 
do 
 cp $line other_live_photos 
done < other_live_photos.csv
while read line
 do 
   if [ -f  $line ] 
   then
    cp live_photos/$line other_live_photos 
   fi
 done < other_live_photos.csv

Bash script: While loop with If statement results in infinite loop

will be helpful for those in need You're never asking inside the loop, so the answer will never change. Hence the infinite loop. What you want to do is read answer inside the loop (and Use More Quotes™).
By the way, a typographic quote like the one you're using has no special meaning in Bash, so it doesn't need to be escaped.
