wait for ssh remote commands.
 
Hi,

I'm running a scripts that launches remotely another script with ssh. Here's the script:

main.sh
Code:
ssh user@remote "~/script1.sh"
ssh user@remote "~/script2.sh"
Here's the remote script:

script1.sh
Code:
java -jar pkg.jar
script2.sh
Code:
java -jar prg.jar
When I run the main.sh, the script1.sh and script2.sh will be launched. But what I want, is that the main.sh must run script2.sh only after script1.sh ends. What is happening, is that, the main.sh don't wait for script1.sh to ends before run script2.sh.

How can I add this capability?

KISS.

ssh user@remote "~/script1.sh"
sleep 10
ssh user@remote "~/script2.sh"

Why is it not possible to put both commands in a single script?

you can do something like this

script1.sh:
Code:
java -jar pkg.jar
echo 1
main.sh:
Code:
VAR=`ssh user@remote "~/script1.sh"`

# i do this echo to see if $VAR contains something
echo $VAR

if [ $VAR == 1 ]; then
ssh user@remote "~/script2.sh"
else
echo did not run
fi
maybe this works?

A smarter answer better that KISS, is like Nylex said. Put everything in one script. This is simple, and does not use the command "sleep" that was really unnecessary.

zordrak 04-14-2011 08:22 AM
My response was based on the assumption that there was a reason the scripts are separate. I don't like to answer a post with "you're doing it wrong" if I don't have detailed context.

nvm :p

zordrak, It's not you're doing wrong. I simply don't know when script1.sh would end. It can take minutes, just like it can take hours. I din't explain that because I just didn't remembered. Anyway, thanks for the help also.

By the way, not related to the post, it exists so many acronyms, that I simply don't understand all. The KISS acronym is new for me. And by the way, what nvm means?
