Two approaches....
1. Search for any of the words on each line and every time you find one, add it to a hash... e.g. $somehash{"Renaldo"} = 1;
When you've finished scanning the whole file, check the resulting hash for the existence of all the words....
if (exists $somehash{"Renaldo"} && exists $somehash{"loosers"} && exists ... ) { send email ... }
Something like that....
OR....
You could try a pattern like
$FILEBUFFER =~ /(A|B|C|D).+(A|B|C|D).+(A|B|C|D).... /is
You simply repeat the alternatives over and over again separated by one or more of any character, and that way you catch all of them if present no matter what the order.... You have to test the resulting capture to see if all words are present... Note the "is" at the end of the pattern... "i" causes case to be ignored, and "s" says to count a newline as one of the "any characters" which lets you match across lines... Note that in this case $FILEBUFFER contains the WHOLE file (see READ()), not a line....

shift(1) User Commands shift(1)
NAME
shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words
SYNOPSIS
sh
shift [n]
csh
shift [variable]
ksh
* shift [n]
DESCRIPTION
sh
The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1.
csh
The components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
not to be set or to have a null value.
ksh
The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can be any arithmetic expression that
evaluates to a non-negative number less than or equal to $#.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
