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<column #>

The above script line can be 
used to extract a column from 
the output of a ps command for 
a particular user ($LOGNAME).
