Storing output into a variable

My script below seems to be choking because I need the the output of the find command to be stored as a variable that can then be called by used lower in the script.

Code:
#!/bin/bash
cd "/resumes_to_be_completed"
var1=find . -mmin -1 -type f \( -name "*.doc" -o -name "*.docx" \)
snd="notification@domain.com"
recp="myemail@domain.com"


while inotifywait -e create /resumes_to_be_completed; 
     do sleep 10; 
     sudo chmod -R 777 /resumes_to_be_completed/; 
     cat $var1 | uuencode $var1 | sendmail -F "New Resumes" -f $snd $recp ; done

I run the script and it appears fine until it is triggered.



Code:
user@resumes:/scripts# ./new_resumes.sh
Setting up watches.
Watches established.
/resumes_to_be_completed/ CREATE foo.doc
uuencode: invalid option -- 'i'
Try `uuencode --help' for more information.
cat: invalid option -- 'm'
Try `cat --help' for more information.

As you can see its erroring out at the uuencodeportion and that appears to be because the output of the find command isnt being stored.

var1 really needs to be the name of a temporary file. Environment variables are not suitable for storing lists of files. Your "find" in not running at all, the environment variable $var1 just contains the command.

Code:
# For example:
var1=/tmp/mytemporaryfilename.txt
find . -mmin -1 -type f \( -name "*.doc" -o -name "*.docx" \) > ${var1}

Now $var1 is the name of a file, cat and uuencode should not error.
Personally I don't know about "inotifywait" and have not used "sendmail" in this manner.
