1. Using the file to verify type and add proper extensions

Now, the second script is in this format modifyXtension "dir1" "dir2" "dir" "..." "dirn".
Where modifyXtension is the name of the script and "dir1" "dir2" "dir3" etc. any number of existing directories inside the current directory.
For each directory, the script must verify (with the file command for example) each and every file type and if it finds one or more that is HTML or JPEG, it must add the .html and .jpg extensions respectively to them for many of these files do not have the right suffix. If the directories contain sub-directories I would also like to search them.

Here is the source code of the second script:
#!/bin/bash
echo Start > result
ftpe="html:jpeg "
Ext=".html:.jpg"

 for fi in `ls ./$dir`;do
  chf=1
    while [ $chf -le 8 ]
    do
      tpe=`echo $ftpe |cut -d: -f$chf`
      xts=`echo $Ext |cut -d: -f$chf`
      fls=`file -ib ./$dir/$fi | grep "$tpe"`
      test `echo $fls |wc -w` -gt 0 && cp ./$dir/$fi `echo ./$dir/$fi |sed "s/$xts//g"`$xts
      chf=`expr $chf + 1`
  done
done
done

The script seems to work somewhat but I am not satisfied with it. Maybe there is a better or more efficient way to write it + the directories that contain sub-directories are not being searched extensively.

As usual, any help is welcome.
