INFO : ${result} = <result object with rc 1> if I use run process to execute a shell script

[Sahil Sharma]

Hi Guys,

I have just started working on Robot and have very little idea of python too. 

So I created a shell script to complete my task on a linux system.

When I execute the script on the linux system itself , it works flawlessly .

But when I try using Robot I am unable to retrieve any information ( I used Run Process , Execute Command , Start Process etc ) in each case I get either "command exited with return code 127" or "command exited with return code 1"

Ill just put in what I have written on ride

1st CASE

open connection 1xx.xxx.xx.xx

Login user passwd

${result} = Run Process fillrcv.sh argument shell=true

Should Be Equal ${result.stdout} SUCCESS for(text i need in the result)

OUTPUT

20171013 18:01:15.755 :  INFO : Waiting for process to complete.

20171013 18:01:15.896 :  INFO : Process completed.

20171013 18:01:15.896 :  INFO : ${result} = <result object with rc 1>

20171013 18:01:15.911 :  FAIL :  != SUCCESS for

Ending test:   AUTOMATION THROUGH ROBOT.Wte

Another case

open connection 135.249.91.13

Login ainet ainet1

Execute command fillrcv.sh c

OUTPUT

20171013 18:11:08.890 :  INFO : Executing command 'fillrcv.sh c'.

20171013 18:11:08.906 :  INFO : Command exited with return code 127.

Ending test:   AUTOMATION THROUGH ROBOT.TC2

Not sure , what to do .. I was unable to find how to use environment variable , so I included the base path for all in built commands like grep sed awk etc. but to no avail .

I have been trying things for almost a week now.

Could you please help?

Regards,

Sahil

Well, you did not say what Library are you using. I'll assume that it is SSHLibrary.

The Run Process keyword is running on the host system where you run robot. You probably want to run the script on the remote server where you connect and logged in. For that, you need to make sure the script is there (probably by uploading it just when needed), and use normal SSHLibrary keywords to Write and Read commands output.

Hi,

Thanx for the input. I was just about to update my wuestion . you are right , I used Write and Read and it was bang on target .

But I am stuck at an issue , I am using 

Write sh fillrcv.sh c

Set Client Configuration prompt=#

${output}= Read Until Prompt

which fails after 3 seconds

Login user passwd

Write su root

Write rootpasswd

Write sh fillrcv.sh c

${output}= Read Until Regexp .*good bye.*

same is the case for Read Until Regexp . 

I tried increasing the timeout to 120s or 2 minute but to no use , as Read is not taking a timeout argument . Any suggestions how to implement a bigger timeout for this case?

Really appreciate your help. 

Regards,

Sahil

I "think" that the prompt should be defined before the connection.

Does the timeout really exist when you perform manually the steps?

Would you improve your strategy of running commands like `root` user? For example using the "su -c" to run the command at once.

Or adding your user to SUDOERS to not have to use a password (for the specific command, or all).

There is a workaround for problematic timeouts, which is using: Wait Until Keyword Succeeds

Good luck
