Shell Programming and Scripting

I have a script in local server
cd /home/dell/work/BOP/testdir
./processchk po (here processchk is a script & po is passed as an argument)

Now I want to execute this script from remote server

Code:

ssh $username@$hostname "cd /home/dell/work/BOP/testdir; ./processchk po"

But Its getting error
ksh: ./processchk: cannot execute

Getting what error?

If the folder /home/dell/work/BOP/testdir/ doesn't exist on the remote server, cd /home/dell/work/BOP/testdir/ won't work on the remote server.

If the file processchk doesn't exist on the remote server. ./processchk won't work on the remote server.

To feed it into the remote end, you must tell the shell to feed it into the remote end.

ssh username@host exec /bin/sh -s arg1 arg2 arg3 < /path/to/script.sh

Beware that stdin won't be available for keyboard input because it's occupied feeding a script into the remote server.

According to your suggestion, I have to pass only one arg for my script, so I used the below code

Code:

ssh $username@$hostname exec /bin/sh -s po < /home/dell/work/BOP/testdir/processchk

OUTPUt i got is

Code:

bash: /home/dell/work/BOP/testdir/processchk: No such file or directory

It means what it says: No such file or directory. Double-check that it's really where you think it is on your local server, and that you didn't somehow add carriage returns to your code (happens if you edit scripts with MS Notepad, etc).

the below code is getting accurate results...but Im unable to execute script..

Code:

ssh $username@$hostname ls -ltr /home/dell/work/BOP/testdir;

Then the script is not on the local machine, it's on the remote one.

Code:

ssh user@host /path/to/file arg

If that doesn't work, there's something wrong with the file's contents or permissions.
