Script to Remove a Letter at the End of some Directories

Let's suppose I have a directory with this Structure:

enter image description here

I am making a script that removes the letter "x" in those cases when there is one at the end in order to have this:

enter image description here

So, I was thinking to do a For Loop that goes to each directory and then take the last part of the folder path

for d in Fruits_and_Vegetables/*/
do
     (cd "$d" && Fruit_or_Vegetable=`basename "$PWD"`)
done

The problem is that I am not sure how to tell to go and take only the last Directory

And then, I was thinking in modifying the string

echo $Fruit_or_Vegetable | awk '{print substr($1, 1, length($1)-1)}'  # substr(s, a, b) : it returns b number of chars from string s, starting at position a. 
                                                                      # The parameter b is optional, in which case it means up to the end of the string.

The problem is that I don't know how to tell AWK to consider "Moscato Giallox" as just one word, because when I execute the command it returns "Moscat Giallox" instead of "Moscato Giallo" .. also I guess I have to place an if statement to see if the last letter is x, and only execute the command in those cases.

Could you give me some suggestions, thanks.

shopt and Parameter Expansion parsing can make that pretty easy. Starting with your directory structure above:

$: find @(Fruits|Vegetables)
Fruits
Fruits/Grapes
Fruits/Grapes/Muskat Grape
Fruits/Grapes/Muskat Grape/Muscat Ottonel
Fruits/Grapes/Muskat Grape/Muscato Gallox
Fruits/Mangoes
Fruits/Mangoes/Ataulfo Mango
Fruits/Mangoes/Tommy Atkins Mangox
Vegetables
Vegetables/Potatoes
Vegetables/Potatoes/Ratte Potatox
Vegetables/Potatoes/Yukon Gold Potato

Code for the changes you want.

shopt -s extglob  # allow fancy @(...) construct to specify dirs
shopt -s globstar # add double-asterisk for flexible depth
for d in @(Fruits|Vegetables)/**/*x/ # *EDITED* - added trailing / for dirs only
do echo "mv \"$d\" \"${d%x/}/\" "   # show the command first
         mv "$d" "${d%x/}/"         # rename the dirs
done

Output from the echo statements:

mv "Fruits/Grapes/Muskat Grape/Muscato Gallox/" "Fruits/Grapes/Muskat Grape/Muscato Gallo/"
mv "Fruits/Mangoes/Tommy Atkins Mangox/" "Fruits/Mangoes/Tommy Atkins Mango/"
mv "Vegetables/Potatoes/Ratte Potatox/" "Vegetables/Potatoes/Ratte Potato/"

Result: 

$: find @(Fruits|Vegetables)
Fruits
Fruits/Grapes
Fruits/Grapes/Muskat Grape
Fruits/Grapes/Muskat Grape/Muscat Ottonel
Fruits/Grapes/Muskat Grape/Muscato Gallo
Fruits/Mangoes
Fruits/Mangoes/Ataulfo Mango
Fruits/Mangoes/Tommy Atkins Mango
Vegetables
Vegetables/Potatoes
Vegetables/Potatoes/Ratte Potato
Vegetables/Potatoes/Yukon Gold Potato
