Unix Tip #4452- May 20, 2013

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).
