不被识别为命令 - bash

我写了一个bash脚本,它接受一组参数,并根据我们做不同的事情.所以在这种情况下我想说:

./acorn.sh aisiscore install

但它转到我的错误消息,指出第一个参数没有重新组合,我应该使用aisiscore或资产.我检查了拼写,我是对的,我没有正确检查参数吗？

#!/bin/bash

set -e

function checkCoreArgument(){
  if [[ $1 == 'aisiscore' ]]
  then
    checkAisisArguments
  elif [[ $1 == 'assets' || $1 == 'asset' ]]
  then
    checkAssetsArguments
  else
    echo "$1 is not recognized. Please try aisiscore or assets"
  fi
}

function checkAisisArguments(){
  if [[ $2 == 'install' ]]
  then
    installAisisCore
  elif [[ $2 == 'update' ]]
  then
    updateAisisCore
  elif [[ $2 == 'components' ]]
  then
    callCompomnentsCheck
  else
    echo "$2 is not recognized. Please try install or update."
  fi
}

function checkAssetsArguments(){
  if [[ $2 == 'install' ]]
  then
    installAssets
  elif [[ $2 == 'update' ]]
  then
    updateAisisCore
  else
    echo "$2 is not recognized. Please use install or update."
  fi
}

function installAisisCore(){
  cd scripts/install/
  chmod +x InstallAisisCore.sh
  sudo InstallAisisCore.sh
}

function updateAisisCore(){
  cd scripts/update/
  chmod +x UpdateAisisCore.sh
  sudo UpdateAisisCore.sh
}

function installAssets(){
  cd scripts/install/
  chmod +x InstallAssets.sh
  sudo InstallAssets.sh
}

function updateAisisCore(){
  cd scripts/update/
  chmod +x UpdateAssets.sh
  sudo UpdateAssets.sh
}

function callCompomnentsCheck(){
  cd scripts/install
  chmod +x InstallComponents.sh
  sudo ./InstallComponents.sh
}
