recdel

RECDEL(1)							   User Commands							 RECDEL(1)

NAME

       recdel - remove records from a recfile

SYNOPSIS

       recdel [OPTIONS]... [-t TYPE] [-n NUM | -e EXPR | -q STR | -m NUM] [FILE]

DESCRIPTION

       Remove (or comment out) records from a rec file.

       -c, --comment
	      comment out the matching records instead of deleting them.

       --force
	      delete even in potentially dangerous situations, and if the deletion is violating record restrictions.

       --no-external
	      don't use external descriptors.

       --verbose
	      give a detailed report if the integrity check fails.

       --help print a help message and exit.

       --version
	      show version and exit.

   Record selection options:
       -i, --case-insensitive
	      make strings case-insensitive in selection expressions.

       -t, --type=TYPE
	      operate on records of the specified type only.

       -e, --expression=EXPR
	      selection expression.

       -q, --quick=STR
	      select records with fields containing a string.

       -n, --number=NUM,...
	      select specific records by position, with ranges.

       -R, --random=NUM
	      select a given number of random records.

       If  no  FILE is specified then the command acts like a filter, getting the data from standard input and writing the result to standard out-
       put.
