Remove duplicate entry in one line

Can anyone help me how can i print only the unique entry in a line?

MI_AP MI_AP MI_CM MI_MF
RC_NAP MBS_AP SF_RAN MBS_AP NT_CAR

so that it will on output the one unique entry per line.

MI_AP MI_CM MI_MF
RC_NAP MBS_AP SF_RAN NT_CAR

I can't find the same situation on the knowledge base.

Code:
while read mLine
do
  echo $mLine | tr ' ' '\n' | sort | uniq | paste -d' ' -s -
done < input_file

if the order matters...

nawk -f kharen.awk myFile.txt

kharen.awk:
Code:
!NF
{
  split("", arr)
  for(i=1; i<=NF; i++) {
    printf("%s%s", ($i in arr) ? "" : $i " ", (i==NF) ? "\n" : "")
    arr[$i]
  }
}

Vgersh,
Your solution would not print blank or empty lines.

Ah, good catch - edited the previous post!

btw, 'sort -u' = 'sort | uniq'

It works now -- great!
In any event, here is another solution in shell only:
Code:
while read mLine
do
  echo $mLine | tr ' ' '\n' > Temp
  cat -n Temp | tr '\t' '|' | sort -t'|' -k2 | uniq +7 | sort | sed 's/.*|//'
| paste -d' ' -s -
done < input_file
