I am trying to install some software tool onto my Ubuntu 16.04 partition. The install script kinda breaks here:

getInstalledLegacyPXIRMPackage() {
    part=`$RPM -q $kLegacyPXIRMBaseName`
    if [ $? -eq 0 ]; then
        echo $part
        return
    fi
    echo ""
}

The error message I get is bash: -q: command not found.

This is part of an INSTALL file for a 32-bit version of labview 2012.

What is this error and what do I do to fix it? Thanks!

Edit: Okay sorry, technically, it does not break at the func definition. It breaks when it is called here:

if [ "$(getInstalledLegacyPXIRMPackage)" != "" ] && [ "$(getIncludedPXIPSPackage)" == "" ]; then
.
.
.
fi

    Think about what happens if the variable RPM is empty? (or if you tried to run a command like $foo arg otherarg with never having set foo) – ilkkachu Dec 11 '17 at 18:11
  • Checking your code with shellcheck is a great start. – PesaThe Dec 11 '17 at 18:34
  • Also, Ubuntu, being derived from Debian, uses apt for its package management rather than rpm or yum. – DopeGhoti Dec 11 '17 at 18:36
  • Hmm, I hope the code you're really trying to run has normal spaces instead of the ones in this code block (I'm not sure what they are) – ilkkachu Dec 11 '17 at 18:51

The error is due to the variable RPM being empty or undefined at the time of executing the getInstalledLegacyPXIRMPackage function.

If $RPM is empty or undefined, the line

part=`$RPM -q $kLegacyPXIRMBaseName`

will be interpreted as an assignment of the result of the command -q $kLegacyPXIRMBaseName.

Make sure that you assign the proper value to RPM (and to kLegacyPXIRMBaseName).
