[SOLVED]Find files by mime type

Hello!
Here is my script that should search for files of a certain mime type. It finding but cannot show that they are equal even if echo shows that they are equal in output. Is it any invisible symbols for output that must be removed before comparing?

#!/bin/bash
DESTINATION='/tmp'
FTYP='XX'"image"
STYP=""
#STYP="jpeg"
if [ 'XX'"$1" != 'XX' ];then
 if [ 'XX'"$STYP" != "XX" ];then 
  echo searching with a subtype without cutting > /dev/null
GTawk='XX'"$( xdg-mime query filetype "$1" | awk -F'/'  '{print $1 $2}' )"
#GTsed='XX'"$( xdg-mime query filetype "$1" | sed 's/\///m'  )"
 else
#cutting everything after the '/' symbol
GTawk='XX'$(xdg-mime query filetype "$1" | awk -F'/' '{print $1 }' )
#GTsed='XX'$(xdg-mime query filetype "$1" | sed 's/\/[^,]*$//' )
 fi
 else
echo command line is empty
fi
if [ "$FTYP$STYP" != "$GTawk" ];then 
 echo The $1 file is not what we need:$FTYP$STYP'|'$GTawk: > /dev/null
 echo $(xdg-mime query filetype "$1") > /dev/null
else
#Actions if found
echo found $(echo $FTYP | sed 's/^XX//m'  ) in  $( echo $GTawk| sed 's/^XX//m' ) > /dev/null
if [ -d "/tmp" ]; then
echo $(xdg-mime query filetype "$1") ;
 cp -v "$1" /tmp
  else
echo The destination doesn't exist, cannot do any action';
fi
fi

#log details in the file
#FileSize="$(du /tmp/found-mime-types-details.log -h | awk '{print $1}' | awk -F'M' '{print $1}')";
#This will limit the size of the log file by 20M
if [ "XX" == "XX"$(du /tmp/found-mime-types-details.log -h | awk '{print $1}' | awk -F'M' '{print $1}' | grep "M"$ | sed 's/K//m' | sed 's/B//m')  ]; 
then
FileSize=0;
fi
if [ "$FileSize" -gt "1" ]; then 
 echo The Log file "/tmp/found-mime-types-details.log" is too big;
#rm /tmp/found-mime-types-details.log
 else 
#Creating a log file
  echo  "$1" '|' $GTawk >> /tmp/found-mime-types-details.log ;

fi

The script without safety checks:

#!/bin/bash
FullNameOfTheMime="image/jpeg"
MergedCMD="$( xdg-mime query filetype "$1" | sed 's/\///m'  | awk -F';' '{print $1}')"
MergedFN="$( echo $FullNameOfTheMime | sed 's/\///m'  )"
#echo "$MergedCMD";
if [ "$MergedCMD" == "$MergedFN"  ];
then echo The file $1 found ;
fi;

"GTawk" does same as "GTsed", I added both just for have one more alternativ for the same jobb. But still the same problem, it might be any in the begin or end of the string.
The script is made for the file recovery with "find * -type f -exec ./img-recovry.sh "{}" \;"

I have edited my post and extended the script funtionality.
