simple count script outputting mass errors
script outputting [: 100: missing ] cant find anything wrong with the script either... :[

Code:
#!/bin/sh
#count execution script

time=0

while [ $time -le 1000 ]
do 



if [ $time -le 100 ]
  then
  time=`expr $time + 1`
  if [ $time = 100 ]
    then
    echo "The current tick is 100"
  fi
fi

if [ $time -gt 101 -le 200]
  then
  if [ $time = 200 ]
  time=`expr $time + 1`
    then
    echo "The current tick is 200"
  fi
fi

if [ $time -gt 201 -le 300]
  then
  time=`expr $time + 1`
  if [ $time = 300 ]
    then
    echo "The current tick is 300"
  fi
fi

if [ $time -gt 301 -le 400]
  then
  time=`expr $time + 2`
  if [ $time = 400 ]
    then
    echo "The current tick is 400"
  fi
fi

if [ $time -gt 401 -le 500]
  then
  time=`expr $time + 2`
  if [ $time = 500 ]
    then
    echo "The current tick is 500"
  fi
fi

if [ $time -gt 501 -le 600]
  then
  time=`expr $time + 2`
  if [ $time = 600 ]
    then
    echo "The current tick is 600"
  fi
fi

if [ $time -gt 601 -le 700]
  then
  time=`expr $time + 5`
  if [ $time = 700 ]
    then
    echo "The current tick is 700"
  fi
fi

if [ $time -gt 701 -le 800]
  then
  time=`expr $time + 5`
  if [ $time = 800 ]
    then
    echo "The current tick is 800"
  fi
fi

if [ $time -gt 801 -le 900]
  then
   if [ $time = 900 ]
    then
  time=`expr $time + 5`
    echo "The current tick is 900"

if [ $time -gt 901 -le 1000]
  then

    then

fi

done

There are numerious errors in your code. The error you showed us relates to the fact that you are not putting a space in front of all the ']''s associated with if statements.

Furthermore, your logic is wrong. Check out the following
Code:
#!/bin/sh
#count execution script

time=0

while [ $time -le 1000 ]
do

  time=`expr $time + 1`

  if [ $time = 100 ]
  then
       echo "The current tick is 100"
  fi
  if [ $time = 200 ]
  then
     echo "The current tick is 200"
  fi
  if [ $time = 300 ]
  then
     echo "The current tick is 300"
  fi
  if [ $time = 400 ]
  then
     echo "The current tick is 400"
  fi
  if [ $time = 500 ]
  then
     echo "The current tick is 500"
  fi

  if [ $time = 600 ]
  then
     echo "The current tick is 600"
  fi
  if [ $time = 700 ]
  then
     echo "The current tick is 700"
  fi
  if [ $time = 800 ]
  then
     echo "The current tick is 800"
  fi
  if [ $time = 900 ]
  then
     echo "The current tick is 900"
  fi
  if [ $time = 1000 ]
  then
     echo "The current tick is 1000"
  fi
done

Note that this can be simplified even further to

Code:
#!/bin/sh
#count execution script

time=0

while [ $time -le 1000 ]
do

  time=`expr $time + 1`
  tick=`expr $time % 100`

  if [ $tick = 0 ]
  then
       echo "The current tick is $time"
  fi

done

and if we really wanted too, we could eliminate a couple of more lines of code.

I looked over my code and i had serveral instances where there was a ] directly after a numerical value. thanks for pointing that out, and yes this script was an early one with serveral errors. Got it to work thanks to your help, the shorthand version blew me away, but i wasnt looking for simplicity in this excersise just repetiton so i can get used to the format etc etc..
