Is the pattern of all the lines in the file the same as the three shown here? If yes, this is how you can do it:
Code:
# cat testfile 234A dept of education 9788 dept of commerce 8677 dept of engineering # while read first rest; do > echo $first:$rest > done < testfile 234A:dept of education 9788:dept of commerce 8677:dept of engineering

Code:
sed 's/\(....\) \(.*\)/\1;\2/' filename Code:
awk '{
for(x=1; x<=NF; x++)
{
if ( x==1 )
{
printf $x";";
}
else
{
printf $x" ";
}
}
printf "\n";
}' filename
