executing parameter file in a unix remote server

Question

I am trying to run a script remotely using ssh and the need use some parameters from remote server. Kept all parameters in remote server location temp/test/test.prm file. Getting an error saying " invoke.sh: line 20: . /temp/test/test.prm: No such file or directory "

See below for sample script. Have very basic knowledge in scripting so plz direct me

#!/bin/sh
Param1=$1
Param2=$2

ssh usr@Server1

          . ${Param1}/Client/scripts/Sample1.prm

 cd  $prmHome/$prmSetPath

 ls | sed '/\.log$/d' >  $prmHome/$prmScript/Filelist.txt

 cd $prmHome/$prmScript

 while read LINE

 do

 ExportFilName=$LINE

 ./conversion.sh $prmHome/tmp_export/convert_$Param2.csv  $prmHome/$prmSetPath/'$ExportFilName'

 done < Filelist.txt


rm -rf   $prmHome/$prmScript/Filelist.txt

exit 0



Content of  Sample1.prm
prmHome=/iis/home
prmSetPath=/export/set
PrmScript=/Client/scripts

I have tried the same trough command line after connecting to remote server using ssh and it is working, but when I am trying to do the same through a script (invoke.sh) its throwing no such file or directory error

Looks like you're trying to source your param file. But why? Is it a shell script or what? — Samuel

Or just a general question, what part of your code you intend to run on remote host ? — deimus

UPDATE

This is unclear and will not work !

ssh usr@Server1
          . ${Param1}/Client/scripts/Sample1.prm

As mentioned you should use

ssh usr@Server1 ". ${Param1}/Client/scripts/Sample1.prm"

format first.

And secondly what you expect following command to do ?

. ${Param1}/Client/scripts/Sample1.prm

Notice that there is a space in between . and the path, which is a synonym for source. So also check if the Sample1.prm have valid commands.

Looks like you are not running any ssh shell command on remote host but only on your local host.

How exactly you are running the ssh shell command ?

The code snippet in your example is poorly formatted. The general structure should look like this e.g.

ssh user1@server1 date

or
ssh user1@server1 'df -H'

Please revise you invocation script, or make the formatting in the question appropriate.

I need to run a script in remote server, but for which I need to pass some parameters. I am trying to invoke the same script from local server through another script. So thought in my local script first connect to remote server using ssh( I am not sure whether this is the right way, doing first time ) and then I can read a parameter file present in remote server and then use some of the parameters from the parameter file as to run remote script ).

The code in your question has nothing to do what you want to do. You should use following structure for parameters with multiple command ssh user1@server1 'df -H'

This is absolutely unreadable. Please copy the code into your question and format it !

. My intention is of ' . ${Param1}/Client/scripts/Sample1.prm ' this command is to execute this file so that I can use the parameters mentioned in Sample1.prm file. and all the code after this line ( my expectation is ) should execute on remote server

If you intend to run the other lines too then the best will be to create a script with the content which you want to run on each remote host. Copy the script to each remote host and then execute it via ssh shell command.

Update:

If you want to execute your code on remote server via ssh, you can do following:

Create separate file my_script.sh for your code you want to run remotely, and paste following code:

 #!/bin/bash
 function my_function() {
    prmHome=$1
    prmSetPath=$2
    PrmScript=$3

    cd  $prmHome/$prmSetPath

     ls | sed '/\.log$/d' >  $prmHome/$prmScript/Filelist.txt

     cd $prmHome/$prmScript

     while read LINE

     do

     ExportFilName=$LINE

     ./conversion.sh $prmHome/tmp_export/convert_$Param2.csv  $prmHome/$prmSetPath/'$ExportFilName'

     done < Filelist.txt  
     rm -rf   $prmHome/$prmScript/Filelist.txt  

    exit 0 
  }

Then you can call you function remotely, by sourcing your file on remote server:

ssh usr@Server1 '. my_script.sh; my_function "/iis/home" "/export/set" "/Client/scripts"'

That's it :)

This code will not work:

ssh usr@Server1

          . ${Param1}/Client/scripts/Sample1.prm

Change it like that:

ssh usr@Server1 ". ${Param1}/Client/scripts/Sample1.prm"

Thanks, but I want execute all the code which mentioned after this line on remote server( server1) only. how can I do that?

Samuel Over a year ago

@Sham hmm, ok but why not put all your code in separate file and then call it via ssh, like that: ssh $my_server ". /<somepath>/myscpritp.sh; my_function $param1 $param2" ?

Sham Over a year ago

can you explain little more. put all code means( all code which I need to run on remote server ?) what do you mean by my_function . Since I posted the code the original post can you make out of it. Sorry not much idea on ssh all

Sham Over a year ago

Thanks Samuel. Let me try and will let you know

Sham Over a year ago

I think the call function syntax is incorrect. not executing
