NAME
DamHfdSelect - Select records from Hfd structure.
SYNOPSIS
DamHfdSelect [ -Kn ] -h hfd [ -k recordKey ] [ -l keyList ]
DESCRIPTION
DamHfdSelect gets a list of hfd record key_numbers by option analysis or on standard input and prints corresponding records. On standard input, keys may be separated by spaces, tabs, newline, colon, semicolon, slash.
OPTIONS
-hhfd defines hfd file from which records are selected. Only radical (without suffix) must be given.
-i insert mode, if set the input stream is composed of an extracting key followed by a tabulation
mark and the end of record which will be copied.
-K if set, record key will be copied on standard output.
-krecordKey introduces the a for extracting a record and printing it.
-lkeyList list of keys to be extracted. Authorized separators are the same than for standard input.
-n If set, no read operation will be done on stdin. (in this case, DamHfdSelect is only driven by
parameters)
EXAMPLE
Reading record key 012314 on hfd mybase.hfd:
DamHfdSelect -n -h mybase -k 012314
