I'm stuck
I defined paths for dir1 through dir13 as variables but I can't get the loop to add the number to the "dir" to create "dir1" and then use it as the defined variable.
This is my test code:
Code:
######################################
# dir1 through dir13 defined previously
n=1
num=1


run=13 # How many directories are we working on?
(( run += n )) # Add one to the number of directories

################################
while (( $num < $run ))
do
      echo $dir$num
    (( num += n )) # When num = run exit loop
    
done

Instead of echoing the defined path for variable "dir1, dir2 ..." it echos "dir1" and "dir2," literally.
If I echo "$dir1" by adding it manually, I get the defined path as desired.
Why won't $dir$num echo as the path?

locate

SLOCATE(1)						      General Commands Manual							SLOCATE(1)

NAME

       slocate - Security Enhanced version of the GNU Locate

SYNOPSIS

       slocate [-qi] [-d <path>] [--database=<path>] <search string>

       slocate [-i] [-r <regexp>] [--regexp=<regexp>]

       slocate [-qv] [-o <file>] [--output=<file>]

       slocate [-e <dir1,dir2,...>] [-f <fstype1,...>] <[-l <level>] [-c] <[-U <path>] [-u]>

       slocate [-Vh] [--version] [--help]

DESCRIPTION

	  Secure  Locate  provides  a  secure way to index and quickly search for files on your system. It uses incremental encoding just like GNU
       locate to compress its database to make searching faster, but it will also store file permissions and ownership so that users will not  see
       files they do not have access to.

	  This	manual	page  documents  the GNU version of slocate.  slocate Enables system users to search entire filesystems without displaying
       unauthorized files.

   OPTIONS
       -u     Create slocate database starting at path /.

       -U <dir>
	      Create slocate database starting at path <dir>.

       -e <dir1,dir2,...>
	      Exclude directories from the slocate database.

       -f <fstype1,...>
	      Exclude files on specific file systems from the slocate database.

       -c     Parse '/etc/updatedb.conf' when updating the slocate database.

       -l <level>
	      Security level.  0 turns security checks off. This will make searchs faster.  1 turns security checks on. This is the default.

       -i     Does a case insensitive search.

       -q     Quiet mode.  Error messages are suppressed.

       -n <num>
	      Limit the amount of results shown to <num>.

       -r <regexp>
	      --regexp=<regexp> Search the database using a basic POSIX regular expression.

       -o <file>
	      --output=<file> Specifies the database to create.

       -d <path>
	      --database=<path> Specifies the path of databases to search in.

       -h     --help Display this help.

       -v     --verbose Verbose mode. Display files when creating database.

       -V     --version Display version.

VERSION

       Secure Locate v2.6
