Hello, I am attempting to do a search and replace of MD5 hashes contained in a file but am having issues with the special characters contained within the hash. For example: #Just generating random hashes for this example and storing them in variables.

$hash1= `makepasswd --clearfrom=$path/keys/temppw --crypt-md5 --verbos
+e | grep Password=| cut -d"=" -f3`; 
chomp($hash1); 

$hash2=`makepasswd --clearfrom=$path/keys/temppw2 --crypt-md5 --verbos
+e | grep Password=| cut -d"=" -f3`; 
chomp($hash2); 

#I need to update the hashes over ssh because I will be doing this on 
+remote machines, so I'm doing the following to test on the local mach
+ine for now.... 

system("ssh -o StrictHostKeyChecking=no root\@localhost /usr/bin/perl 
+-p -i -e s/$hash2/$hash1/ee hashfile") == 0 
or @errors=(@errors,"\n$server hash update error: $?\n");

Doing the above generates an error similar to this. Bareword found where operator expected at -e line 1, near "s/$/7OWwo4h/FWHShP3" syntax error at -e line 1, near "s/$/7OWwo4h/FWHShP3" Execution of -e aborted due to compilation errors.

Some example hashes..........

What am I doing wrong here?

Thanks in advance...
