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.

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
