何时/如何在测试中使用"=="或"-eq"运算符？

Question

在下面的代码中,我想比较命令行参数和参数,但我不确定将参数与parameters..ie"=="或"-eq"进行比较的当前语法是什么.

#!/bin/bash
argLength=$#
#echo "arg = $1"

if [ argLength==0 ]; then
#Running for the very first
#Get the connected device ids and save it in  an array
  N=0
  CONNECTED_DEVICES=$(adb devices | grep -o '\b[A-Za-z0-9]\{8,\}\b'|sed -n '2,$p')
  NO_OF_DEVICES=$(echo "$CONNECTED_DEVICES" | wc -l)
  for CONNECTED_DEVICE in $CONNECTED_DEVICES ; do
       DEVICE_IDS[$N]="$CONNECTED_DEVICE"
       echo "DEVICE_IDS[$N]= $CONNECTED_DEVICE"
       let "N= $N + 1"
  done
  for SEND_DEVICE_ID in ${DEVICE_IDS[@]} ; do
      callCloneBuildInstall $SEND_DEVICE_ID
  done
elif [ "$1" -eq -b ]; then
  if [ $5 -eq pass ]; then 
      DEVICE_ID=$3
      ./MonkeyTests.sh -d $DEVICE_ID
  else
    sleep 1h
    callCloneBuildInstall $SEND_DEVICE_ID
  fi
elif [ "$1" -eq -m ]; then 
  echo "Check for CloneBuildInstall"
  if [ "$5" -eq pass ]; then 
      DEVICE_ID=$3
      callCloneBuildInstall $SEND_DEVICE_ID
  else
    echo "call CloneBuildInstall"
    # Zip log file and save it with deviceId
    callCloneBuildInstall $SEND_DEVICE_ID
  fi
fi

function callCloneBuildInstall {
  ./CloneBuildInstall.sh -d $SEND_DEVICE_ID
}

来自help test:

[...]

  STRING1 = STRING2
                 True if the strings are equal.

[...]

  arg1 OP arg2   Arithmetic tests.  OP is one of -eq, -ne,
                 -lt, -le, -gt, or -ge.

但无论如何,条件的每个部分都是一个单独的参数[.

if [ "$arg" -eq 0 ]; then

if [ "$arg" = 0 ]; then
