blank - replace a row with blanks
SYNOPSIS
blank [-fc] < tableorlist
DESCRIPTION
blank
replaces all of the values
in each record of a table or list file with spaces.
blank
is used by the
update
command to put a blank
record back into a file while the original record is being
edited.
This effectively locks the record and prevents
others from reading
or updating it while it is in use.
OPTION
- -fc
- use c (instead of TAB) as the input column
separation character.
EXAMPLE
Item^IAmount^ICost^IValue^IDescription$
----^I------^I----^I-----^I-----------$
7^I5^I175^I875^Iscales$
$ row 'Item == 7' < inventory | blank | see
Item^IAmount^ICost^IValue^IDescription$
----^I------^I----^I-----^I-----------$
^I ^I ^I ^I $
see
shows what record 7 looks like before and after
blank.
The spaces replaced the
characters, including spaces, that were in the original records.
