For example: I have 100 folder names saved in a text file, how can I apply different command line in the same for loop for every 10 names? In other words If I want to rename every 10 folders with a different name how can I apply the mv command in the same for loop for every 10 items in the text file?

#!/bin/bash -f
source=PATH TO THE DATA (100 FOLDERS)
for f in $(cat text.txt); do 
mv ${source}/"old folder name" ${source}/" new folder name"
done

since you have them in a text file, you could run two for loops with different index integers and address the files via their positions in the text file:

for (( i=0 ; i<=9 ; i++ )) ; do
  newpos=$i_files
  for (( j=1 ; j<=10 ; j++ )) ; do
     mv "$( sed -n "$(( $i*10+$j ))p" filelist)" "$newpos"
  done
done

since it is about mv you can even use blocks of your input file with sed

 for (( i=0 ; i<=9 ; i++ )) ; do
    newpos=$i_files
    mv "$( sed -n "$(( $i*10+1 )),$(( ($i+1)*10 ))p" filelist)" "$newpos"
 done

Explanation on the sed part: sed -n "4,8p" file will print lines 4 through 8 of file.
