Being cryptic about what you're really trying to do makes it harder to give you any real help. What Ravinder or drl suggested might do exactly what you want.

You could also try this alternative:
Code:
#!/bin/bash
awk '
FNR == NR {
	A[$1, $2]
	next
}
($2, $1) in A {
	printf("echo \"string %s found with numbers %s\"\n", $2, $1)
	printf("echo mv \"somefile1\" \"somefile2\" \"somefile3\" \"/some/other/directory\"\n")
	delete A[$2, $1]
}' file1  file2 | bash

which produces the output:
Code:
string CC found with numbers 3
mv somefile1 somefile2 somefile3 /some/other/directory

where the echo shown in red prints the rm command instead of executing it. (But, of course, you have to actually have awk create the list of files to be moved and create an mv command for bash to execute.

If the names of the files to be moved depend on the values from the matched lines, something more like:
Code:
#!/bin/bash
awk '
FNR == NR {
	A[$1, $2]
	next
}
($2, $1) in A {
	print $2, $1
	delete A[$2, $1]
}' file1  file2 | while IFS= read -r string number
do	printf 'string %s found with numbers %d\n' "$string" "$number"
	echo mv "FileContaining${string}and$number".* "/some/other/directory"
done

might be more appropriate. In a directory that contains the files:
Code:
-rw-r--r--  1 dwc  staff    0 Aug 17 09:28 FileContainingCCand3.1.txt
-rw-r--r--  1 dwc  staff    0 Aug 17 09:28 FileContainingCCand3.4.txt
-rw-r--r--  1 dwc  staff    0 Aug 17 09:28 FileContainingCCand3.7.txt
-rw-r--r--  1 dwc  staff   30 Aug 17 09:04 file1
-rw-r--r--  1 dwc  staff   15 Aug 17 09:04 file2
-rw-r--r--  1 dwc  staff  682 Aug 17 09:05 problem
-rwxr-xr-x  1 doc  staff  532 Aug 17 09:28 tester

it produces the output:
Code:
string CC found with numbers 3
mv FileContainingCCand3.1.txt FileContainingCCand3.4.txt FileContainingCCand3.7.txt /some/other/directory

as long as you keep the echo shown in red. If you remove the echo, it would actually attempt to move those files.
