Thanks,
but here it complains so many $ ./check_file.sh
./check_file.sh: line 8: [: too many arguments

Possible problem with spaces. This one works for me:

No, the problem is the number of arguments to the ls call.
There is a limited number of arguments for a process, and
the glob sys_em_*.txt expanded to more than that number.

What is the number? I tried it with 8192 files:

#>ls -1 file-* | wc -l                                                                 
8192
#>../test.sh 8192
sucess                                         

And my script is:

 #>cat ../test.sh
my_number=$1                                                              
while :
do
  if [ `ls -1 file* | wc -l` == "$my_number" ]
  then
    echo "sucess"
    break
  fi
  echo "test"
  sleep 5
done
