Code:
version=`echo $FOLDER | awk '{split($0,a,"_v");print a[2]}'`

Here you also have removed the ; at the end compare to post above.

Try this and see if it works
version=$(echo $FOLDER | awk '{split($0,a,"_v");print a[2]}')
Its more easy to read a code using $(code) compare `code`

It may be shorten some to:
Code:
version=$(awk '{split($0,a,"_v");print a[2]}' <<< $FOLDER)

I do also not see why you split $0
This may also work
Code:
version=$(awk -F"_v" '{print $2}' <<< $FOLDER)

strstr

STRSTR(3)						     Linux Programmer's Manual							 STRSTR(3)

NAME

       strstr - locate a substring

SYNOPSIS

       #include <string.h>

       char *strstr(const char *haystack, const char *needle);

DESCRIPTION

       The  strstr()  function finds the first occurrence of the substring needle in the string haystack.  The terminating `' characters are not
       compared.

RETURN VALUE

       The strstr() function returns a pointer to the beginning of the substring, or NULL if the substring is not found.

BUGS

       Early versions of Linux libc (like 4.5.26) would not allow an empty argument. Later versions  (like  4.6.27)  work  correctly,  and  return
       haystack when needle is empty.
