Data Eval command with space, quote and bracket characters
Hi,
I am Pradnya Gandhe trying to use in shell script.
I want to use a bit complicated command using eval command in a shell script.
Code:
<path to>\wsadmin.sh -lang jython -conntype NONE -c "AdminApp.install('war file path', '[ -appname IDSWebApp -contextroot /IDSWebApp -MapModulesToServers [[ \"string" IDSWebApp.war,WEB-INF/web.xml WebSphere:server=server1 ]] -MapWebModToVH [[ \"string\" IDSWebApp.war,WEB-INF/web.xml default_host ]] -MapRolesToUsers [[ allusers AppDeploymentOption.No AppDeploymentOption.Yes \"\" \"\" AppDeploymentOption.No \"\" \"\" ]] ]')"

Works correctly as expected on shell prompt
Code:
<path to>\wsadmin.sh -lang jython -conntype NONE
wsadmin>above command

works correctly

I want to use this command in shell script, so I used eval command
eval "command" like following
Code:
eval <path to>\wsadmin.sh -lang jython -conntype NONE -c "AdminApp.install('war file path', '[ -appname IDSWebApp -contextroot /IDSWebApp -MapModulesToServers [[ \"string" IDSWebApp.war,WEB-INF/web.xml WebSphere:server=server1 ]] -MapWebModToVH [[ \"string\" IDSWebApp.war,WEB-INF/web.xml default_host ]] -MapRolesToUsers [[ allusers AppDeploymentOption.No AppDeploymentOption.Yes \"\" \"\" AppDeploymentOption.No \"\" \"\" ]] ]')"

It gives following error->
Code:
pg.sh: command substitution: line 10: syntax error near unexpected token `('
pg.sh: command substitution: line 10: `<path to>\wsadmin.sh -lang jython -conntype NONE -c '"'AdminApp.install('war file path', '[ -appname IDSWebApp -contextroot /IDSWebApp -MapModulesToServers [[ "string" IDSWebApp.war,WEB-INF/web.xml WebSphere:server=server1 ]] -MapWebModToVH [[ "string" IDSWebApp.war,WEB-INF/web.xml default_host ]] -MapRolesToUsers [[ allusers AppDeploymentOption.No AppDeploymentOption.Yes "" "" AppDeploymentOption.No "" "" ]] ]')'"''

I want to know rules to used in eval if command within it contains characters like brackets, quotes, space, etc.

This is all issue of characters which when passed over eval generates error.

Pls guide me.

Thanks and regards,
Pradnya Gandhe

I am lost on several counts here.

If I have a command (for example date) that works at a shell prompt outside of a script, I can run that same command inside a shell script without preceding it by eval. Why do you think you need eval here?

The command that you say works has mismatched double quotes. I can't believe that it is working for you at a shell prompt outside of a shell script for you. And that is assuming that <path to>\wsadmin.sh is not trying to run the to command with input redirected from the file named path and output redirected to the file wsadmin.sh???

Why are you getting diagnostics reporting a problem on line 10 of your script when the script you have shown us only contains one line?

I don't see any command substitution in the command you say is working nor in the shell script you have shown us. Why is the shell you're using complaining about command substitution? Is there a command substitution started on a line in your script before the line you have shown us?

What operating system and shell are you using?

Hi Don,
Yes, you are right.
I dont need to use eval if I have a command that runs successfully out of the shell script.
Now I am calling same command within shell script.
I was UN-necessarily wasting my time to make it work with eval. Somehow it got sleep from my mind that we can use the commands withing shell script.

Thanks for point this out. It saved my day.

Thanks and regards,
Pradnya Gandhe
