or trying to find the mailx on your system you could use the find command "find [search-destination i.e. "/"] -name mailx"
- only this demands you to have the find command embedded on your system, eventhough this is pretty comon on most unixes.
Otherwise you could use "mail" as someone surgested, another one is sendmail which is also possible that you have.
- note that either mailer could be used with a number of parameters, above/below is only shown the most simplified you need; "more {filename} | mailx {you@email.tld}" ~ you could also use the cat instead of more, they do the same in this matter...
- I hope all these surgestions points you out to a solution for your problem.
ps. Putty is very good dump terminal, and note that you are able to configure it in numerous ways, that could help you out while connected to a unix shell.
