Can't launch putty with remote command?

I'm attempting to launch putty via the command line in such a way that it runs a command on the server (I want to create a windows shortcut, to tail a log file)

So far I have a batch file containing this

"C:\Program Files (x86)\PuTTY\putty.exe" -ssh -t -pw -m tail_catalina_out -load "myprofile"

And within my server I have a file at the root directory named tail_catalina_out with the following contents.

tail -f /opt/tomcat/logs/catalina.out

Putty launches and my session starts successfully, but no command appears to be carried out despite this? Am I misunderstanding how this works?

  1. You don't need -ssh with -load profile (and if you use a nonstandard port like my test it doesn't work at all); in fact you don't need it with [user@]host because it's the default

  2. -pw -m tail_catalina_out uses -m as your password (which I hope is incorrect, so you should be reprompted unless publickey auth is set-up) and ignores tail_catalina_out

  3. the file for -m must be local i.e. on the PuTTY machine not on the server (although the commands in it will be sent to, and must be valid on, the server)

Thus: "\path\to\putty" -t -m localcmdfile -load profile

You could also use plink which runs in the console and takes either -m localfile or the actual remote command on the command line after the last option (like the OpenSSH client ssh):

 "\path\to\plink" -t -load profile tail -f remotefile

As usual, you can omit the quotes around the path if it contains no space. Personally I use \progra~2 instead of bothering with "\program files (x86)" but that's just me, and it may depend on a clean install (instead of upgrade).
