Issue in passing multiple parameters in Batch file to remote shell script using Plink

Question

I am running a bat file from windows command line which calls a linux script to copy a file:

WIN_BATCH.bat content:

"C:\plink.exe" -ssh User@%1 -pw "pass123" "/u01/./LINUX_COPY_SCRIPT.sh %1"

LINUX_COPY_SCRIPT content as below:

sshpass -p "pass123" scp /u01/file_1.txt root@$1:/u01/file_1_Copy.txt

When I am running command from Win cmd as below, evereything is working fine, i.e.

Win command prompt:

C:\Scripts>WINbatch.bat 11.111.11.11

Message in CMD:

C:\Scripts>"C:\plink.exe" -ssh [email protected] -pw "pass123" "/u01/./LINUX_COPY_SCRIPT.sh 11.111.11.11"
C:\Scripts>

And the file gets copied from "file_1.txt" to "file_1_Copy.txt"

Now comes the issue, if I modify my scripts as below:

WIN_BATCH.bat content:

"C:\plink.exe" -ssh User@%1 -pw "pass123" "/u01/./LINUX_COPY_SCRIPT.sh %2"

LINUX_COPY_SCRIPT content as below:

sshpass -p "pass123" scp /u01/file_1.txt root@$2:/u01/file_1_Copy.txt

and pass 2 parameter:

Win command prompt:

C:\Scripts>WINbatch.bat 11.111.11.11 11.111.11.11

I'm getting error:

C:\Scripts>"C:\plink.exe" -ssh [email protected] -pw "pass123" "/u01/./LINUX_COPY_SCRIPT.sh 11.111.11.11"
ssh: Could not resolve hostname : Name or service not known
lost connection
C:\Scripts>

WHY ?? If you see the commands fired in both cases are same, as i am passing the same parameter.

HOW I CAN GET THIS WORKING ? The idea to pass multiple parameter because i want to copy file from one env to other at later stage.

I.e. once

C:\Scripts>WINbatch.bat 11.111.11.11 11.111.11.11

is working I'll be doing

C:\Scripts>WINbatch.bat 11.111.11.11 11.111.11.12

Where "11.111.11.11" and "11.111.11.12" are ip of 2 systems.

Why not install Cygwin and write real shell scripts instead of crummy DOS bat files? — Red Cricket

Yeah, but i cant install Cygwin, so need to figure out something which i have... — Rahul

Also I don't see any mistake in this approach, passing multiple parameters is absolutely fine in windows batch file but not sure whats the issue here, even when i am using the same parameter twice.. — Rahul

From the batch you only pass one argument %2 so the shell script can't access $2 as it is not present. — user6811411

You are passing only one argument to LINUX_COPY_SCRIPT.sh:

"C:\plink.exe" -ssh User@%1 -pw "pass123" "/u01/./LINUX_COPY_SCRIPT.sh %2"

But you are trying to use second argument ($2) in the shell script:

sshpass -p "pass123" scp /u01/file_1.txt root@$2:/u01/file_1_Copy.txt

It should be $1:

sshpass -p "pass123" scp /u01/file_1.txt root@$1:/u01/file_1_Copy.txt
