Many examples available online for "bash if" (and other conditional statements)

#!/bin/bash



pkgDir="/tmp/CB/file.pkg"



if [ -d $pkgDir ]; then 

    do this 

else

    do that 

fi

that was fast! thank you.
one last question I want it to exit if the file is on the /tmp/CD/file.pkg
and install if its not there....does the "exit" looks correct? (do I need a "exit 0" or "exit 1")?

thank you very much!

#!/bin/bash



pkgDir="/tmp/CB/file.pkg"



if [ -d $pkgDir ]; then 

    exit

else

   installer -pkg /tmp/CB/file.pkg -target /

fi

You're on the right track, and yes, ideally you'll want to use the appropriate exit code

got it thank you again!

Would probably use -e unless that's a non-flat PKG.

A few comments:

• Good idea to save resources and not do the transfer and install if not needed.




• Instead of running the script again and again, just to find out the package is already there you could make a smart group that contains the devices that don't have the package installed, and run it only on these.




• Non-zero exit codes usually indicate that an error occurred. It is useful to stick to that convention and don't use non-zero exit codes to signal something else.




• A package in /Applications? Sounds weird to me.

Cheers,

Matthias

@mschroder thank you for your comments =)

yes you are right a package in Applications doesn't make sense
I didn't explain it correctly, so the package gets download it to /tmp/CD/file.pkg than the scripts run the installer and what it actually happens the file.pkg installs the application into /Applications =)

I will also try your suggestion on using a smart group.

Thank you very much!
