ELIMINATING MULTIPLE SPACES 
Here is a simple script which
 helps in eliminating multiple
 spaces when one wants to
 extract a particular column
 in a set of records from a
 file.
 
 Here is an example to prove
 the same:
 
 ps -u $LOGNAME | tr -s " " : | cut -d: -f
 
 The above script line can be
 used to extract a column from
 the output of a ps command for
 a particular user ($LOGNAME).
