Running script with ssh

Question

I work with machine A and I want to run a script that exists in machine B.

I did the ordinary command:

ssh user@machine_B_adress '. script.sh'

the problem is that I used in the script some commands that cannot be interpret with machine A. So I get command not found: (for example)

ksh: sqlplus:  not found

I tried to open a shh by: ssh user@machine_B_adress

and then run the script, it works!!!

Have you tried ssh user@machine_B_address '/bin/bash -l .script.sh'? — Stefano Falsetto

bash is not installed in the remote machine and I can't install it; Simply, coz I m not allowed to do it — bilel study

could you run the following commands and paste the output: when logged in: which sqlplus ps -ef | grep $$ | grep -v grep and echo "$PATH" and also all 3 as ssh user@machine_B_adress 'which sqlplus' ? — Samuel Kirschner

I get: no sqlplus in /usr/bin /etc ... after executing ssh user@machine_B_adress 'which sqlplus' — bilel study

Assuming that the shell for user@machine_B is bash, the first example 'ssh user@machine_B_adress '. script.sh', bash sets up the shell env differently for interactive/non-interactive sessions.

See man bash about interactive shells

Looks like you can emulate the interactive environment by adding a bash -l -c

$ ssh user@machine_B_address "bash -l -c '. script.sh'

My quick test, I added debug echo to .bash_profile of the remote user

$ ssh foouser@jdsrpi1 "bash --login -c '. foo.sh'"

This is file .bash_profile

foouser 

SHELL = /bin/bash

PATH = /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

Similar scenario for ksh

$ ssh [email protected] "date"

$ ssh kshuser@jdsdrop1 "ksh -l -c date"

This is SHELL(/usr/bin/ksh) file .profile
