I am attempting to execute a binary on my ssh server as soon as I log in. However I may want to push the update of my binary with a single ssh login and execute aswell. My current process for do this is
cat exec | ssh user@host 'cat - > exec; chmod +x exec; ./exec'
This does not work as when I hit the accutal execution it appears to just freeze. I get no response from the server after this. The strange thing is once I have uploaded the file I can simply execute
ssh user@host './exec'
and the file is executed just fine. I know it is reaching the execution process of the binary and the
chmod is correctly setting the executable bit of the file it just will not execute in a single command. Does anyone have any suggestions.
