Bash: for loop; loop through files; remove path and suffix from file names

Credit for the bash for loop goes here: http://www.cyberciti.biz/faq/bash-for-loop/
Credit for the suffix and prefix modifications goes here: http://stackoverflow.com/questions/125281/how-do-i-remove-the-file-suffix-and-path-portion-from-a-path-string-in-bash

Loop through a series of numbers:

#!/bin/bash

for int in 1 2 3 4
do
   echo $int
done

Loop through a series of files and modify the file name; see the Stack Overflow link above for a few more options:

#!/bin/bash

files=pathToFiles/*.tsv

for file in $files
do
   echo $file
   SUFFIX=${file%.*}
   echo $SUFFIX
   NEWNAME=${SUFFIX##*/}.txt
   echo $NEWNAME
done
