SSH Pipeline Steps 2.0.0
Remote host details:
Ubuntu 20.04
Which type shell "SSH Pipeline Steps" uses for logging in to remote hosts? I had set an environment variable using a shell script inside /etc/profile.d/devOpsEnvVars.sh.
export datetime=2021-06-13_20_40_00 export backedUpFileName=ProjectName_$datetime.war
According to the Ubuntu Environment variables documentation,] whenever a "bash" shell login happens, the shell scripts inside /etc/profile.d/ will be executed.
If I login through SSH using regular terminal, then the new variables will be available.
Does "SSH Pipeline Steps" uses "bash" shell for logging in to remote system?
Below are some logs showing the behavior. I have tried accessing "JAVA_HOME" which has been set in /etc/environment file. And it is successfully accessed. But the variables "datetime" and "backedUpFileName" are printing empty lines (Not able to access them).

However I cannot use /etc/environment file because, in each build, I have to keep updating the variables. Writing code to search particular variable and replacing the whole line in "/etc/environment" is not what I'm expecting to do. "profile.d" way is more easy.
Temporarily, as of now, I'm creating shell script in home directory and executing that script, in each "sshCommand" step, and then appending new command after "&&". But I don't want to do like this as well. I want to use Ubuntu features.
Is there is any work around to access Environment variables in proper way?
OR
Is it possible to make "SSH Pipeline Steps" to use "bash" shell, if that is not what being used?
