Is it OK for you to keep the directories to check in a file, so you check (in)existing directories against the file?

Code:
#!/bin/sh

schemaExtractDir="/var/tmp"
while read dir; do
  dir="$schemaExtractDir/$dir"
  if [ -d "$dir" ]; then
    echo "$dir exists, not creating this dir."
  else
    echo "$dir does not exist: creating one for you..."
    mkdir "$dir"
  fi
done < file

exit 0

file is a text file containing directories to create.
Code:
~$ cat file
SchemaExtract
SQL
Count
SchExtArchive

~$ ./script.sh
/var/tmp/SchemaExtract does not exist: creating one for you...
/var/tmp/SQL does not exist: creating one for you...
/var/tmp/Count exists, not creating this dir.
/var/tmp/SchExtArchive does not exist: creating one for you...

NAME
Test::TempDir::Factory - A factory for creating Test::TempDir::Handle objects. SYNOPSIS
my $f = Test::TempDir::Factory->new; my $d = $f->create; $d->empty; # ... $d->cleanup DESCRIPTION
This class creates Test::TempDir::Handle objects with the right "dir" parameter, taking care of obtaining locks, creating directories, and handling fallback logic. ATTRIBUTES
lock Whether or not to enable locking. Defaults to true. lock_opts A hash reference to pass to File::NFSLock. Defaults to "NONBLOCKING" lock_attempts How many times to try to create and lock a dir. Defaults to 2. dir_name The directory under "t_dir" to use. Defaults to "tmp" t_dir Defaults to "t" use_subdir Whether to always use a temporary subdirectory under the temporary root. This means that with a "success" cleanup policy all failures are retained. When disabled, "t/tmp" will be used directly as "temp_root". Defaults to true. subdir_template The template to pass to "tempdir". Defaults to "File::Temp::TEMPXXX". handle_class Defaults to Test::TempDir::Handle. verbose Whether or not to "carp" diagnostics when falling back. If you subclass this factory and add a "logger" method a la MooseX::Logger then this parameter is ignored and all messages will be "warn"ed on the logger. METHODS
create Create a Test::TempDir::Handle object with a proper "dir" attribute. perl v5.10.0 2009-08-10 Test::TempDir::Factory(3pm)
