Como regra geral, você deve evitar analisar ls e certamente não deve fazê-lo com for loop que irá quebrar seus argumentos no espaço em branco (ou o que você tiver definido $IFS para). Uma maneira melhor seria:

for i in /opt/metasploit-framework/*msf; do ln -s "$i" /usr/local/bin/; done

Se você insistir em usar ls , uma maneira mais segura seria:

ls -1 /opt/metasploit-framework/*msf | while IFS= read -r msf; do 
    ln -s /opt/metasploit-framework/"$i" /usr/local/bin/; done
