passing arguments in remote ssh command?
i have a bash script on serverA, when i run the script on the server, it runs fine. the way to run the script is like this ./script "option1"

Now i am trying to call it from local laptop using ssh command, my command is as the following

Code:
ssh serverA ~/script "option1"

and i got error messages, "line 1: syntax error at ''

what could be wrong? How am i going to pass the argument in remote ssh command?

Thanks

Hi.

You need to either escape the tilde (~), or quote the command, otherwise the ~ means the local user's home directory, not the remote one:

Before:
Code:
/Users/scott $ ssh oracle@vm_oracle_10g ~/scripts/myScript opt1 opt2 opt3  
oracle@oracle's password: 
ksh: line 1: /Users/scott/scripts/myScript: not found

After:
Code:
/Users/scott $ ssh oracle@vm_oracle_10g \~/scripts/myScript opt1 opt2 opt3
oracle@vm_oracle_10g's password: 
Hello from myscript @ oracle@vm_oracle_10g
Options passwd were:  opt1 opt2 opt3
/Users/scott $

Aside from that, be careful how you use quotes, especially if you have to mix single and double quotes Smilie

it also helps to wrap your remote command string in quotes...single-quote (') will be handled strictly verbatim, while double-quotes will allow for local variables to be used...

thanks, but in my case, the system treats the ~ as remote home dir, not the local one, since the command gets executed, but the remote system is complaining about the argument part.

line 1: syntax error at ''

Show the script you are trying to run - there is nothing I can see wrong in the command you are running (even given how it's quoted)

I'm surprised that your system knows that ~ should be treated remotely, but I take your word for it Smilie

won't work if the script is only on the local machine and the SQL client is on the remote...unless local and remote are the same machine, of course... :P

Or have the same script in both home directories Smilie

Is the command you show us the actual command you are running? i.e. if your command contains variables, and it's not quoted, then.....
