bash - $PATH macOS, move directory up in the hierarchy- to prefer execution of particular version -


i'm trying execute command (geth) program lives in directory lives in relatively high level of $path, can see here:

enter image description here

the command executing default related version lives in $gopath, $gopath is: 

/users/s.matthew.english/go

the code want execute lives at: 

$home/consensys/pegasys/clients/quorum/0.0_quorum/quorum

i tried add on higher line of ~/.zshrc so: 

#------------------------------------------------------------- # attempt add quorum stuff... #-------------------------------------------------------------  export path=$path:$home/consensys/pegasys/clients/quorum/0.0_quorum/quorum  #------------------------------------------------------------- # related go #-------------------------------------------------------------  export gopath=$home/go  export path=$gopath/bin:$path

but when call which geth still outputs this: 

/users/s.matthew.english/go/bin/geth

even if remove lines:

export gopath=$home/go  export path=$gopath/bin:$path

it still outputs /users/s.matthew.english/go/bin/geth when call which geth, , still find thegodirectory higher in my$path`, so: 

/usr/local/opt/llvm/bin:/usr/local/opt/android-sdk/build-tools/19.1.0:/usr/local/opt/android-sdk/platform-tools:/usr/local/opt/android-sdk/tools:/usr/local/opt/gradle/bin:/usr/local/opt/maven/bin:/usr/local/opt/ant/bin:/users/s.matthew.english/.nvm/versions/node/v7.4.0/bin:/users/s.matthew.english/.rbenv/shims:/users/s.matthew.english/.rbenv/bin:/usr/local/opt/llvm/bin:/usr/local/opt/android-sdk/build-tools/19.1.0:/usr/local/opt/android-sdk/platform-tools:/usr/local/opt/android-sdk/tools:/usr/local/opt/gradle/bin:/usr/local/opt/maven/bin:/usr/local/opt/ant/bin:/users/s.matthew.english/go/bin:/users/s.matthew.english/.rbenv/shims:/users/s.matthew.english/.rbenv/bin:/usr/local/opt/llvm/bin:/usr/local/opt/android-sdk/build-tools/19.1.0:/usr/local/opt/android-sdk/platform-tools:/usr/local/opt/android-sdk/tools:/usr/local/opt/gradle/bin:/usr/local/opt/maven/bin:/usr/local/opt/ant/bin:/users/s.matthew.english/go/bin:/users/s.matthew.english/.rbenv/shims:/users/s.matthew.english/.rbenv/bin:/usr/local/opt/llvm/bin:/usr/local/opt/android-sdk/build-tools/19.1.0:/usr/local/opt/android-sdk/platform-tools:/usr/local/opt/android-sdk/tools:/usr/local/opt/gradle/bin:/usr/local/opt/maven/bin:/usr/local/opt/ant/bin:/users/s.matthew.english/go/bin:/users/s.matthew.english/.rbenv/shims:/users/s.matthew.english/.rbenv/bin:/users/s.matthew.english/.cargo/bin:/users/s.matthew.english/consensys/pegasys/clients/quorum/0.0_quorum/quorum/:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/library/tex/texbin:/users/s.matthew.english/consensys/pegasys/clients/quorum/0.0_quorum/quorum:/users/s.matthew.english/consensys/pegasys/clients/quorum/0.0_quorum/quorum:/users/s.matthew.english/consensys/pegasys/clients/quorum/0.0_quorum/quorum

how can change $path version of geth lives in $home/consensys/pegasys/clients/quorum/0.0_quorum/quorum execute in favour of 1 lives in /users/s.matthew.english/go?

this question related a prior question on ethereum.

edit:

so figured out need append reference quorum @ end of ~/.zshrc file, , affix rest of $path so: 

#------------------------------------------------------------- # attempt add quorum stuff... #-------------------------------------------------------------  export path=$home/consensys/pegasys/clients/quorum/0.0_quorum/quorum:$path

and although move front of $path, nevertheless when call which geth following result (i.e. no change):

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
