ssh - remotely passing and setting a variable

ssh xxx@remote_system " echo $dateVar; date=$dateVar"

I am trying to pass dateVar to the remote system from within the shell script, which I believe works fine and then trying to set the date on the remote server to that of the dateVar variable, but with no success. Can someone please help?

Regards!

From date man page, to set date using the date command you should do date --set=$dateVar. Therefore, in order to change date on a remote system, executing the following should suffice:

  • ssh xxx@remote_system "sudo date --set=$dateVar"

Assuming the date format is correct, you need to remove the = since it creates/sets a variable named date instead of calling the command date:

ssh xxx@remote_system "date $dateVar"

Your user xxx might not have the necessary rights, so you might set up sudo (google for things like sudo and /etc/sudoers) so you can do:

ssh xxx@remote_system "sudo date $dateVar"
