CHECK

Synopsis

HELP:   Parameter for checksum verification
TYPE:   OVERLAY
SYNTAX: CHECK.{VALUE='str'/FILE='str'/STREAM/DUMMY}

Description

The 'check' parameter defines the expected hash (checksum).

The hash can be specified directly or read from a file. For the check file, all rules and replacements are valid which are described under "FILENAME HANDLING" above. For example:

   FILE=STREAM                            ; STDIN is SYSIN on z/OS
   FILE='~.MYCHECK(HASH1)'                ; PDS on z/OS
   FILE='<SYSUID>.MYCHECK2'               ; PS dataset on z/OS
   FILE='~/mycheck3.txt'                  ; Unix path name
   FILE='<HOME>\\hashs\\mycheck4.txt'       ; Windows path name

Currently, checksum files can be in standard GNU format:

   hex_hash_checksum   path_to_orignal_file

HEX:

   hex_hash_checksum

BIN (only if oputput file is selected, else same as HEX):

   bin_hash_checksum

or BSD style:

   ALGO(path_to_orignal_file) = hex_hash_checksum

A check file can contain more than one checksum:

   flcl HASH FILE=*.* OUT=checkfile.txt

which can be used to check each file separately

   flcl HASH FILE=data.bin CHECK.FILE=checkfile.txt

Arguments

• STRING: VALUE='str' - Checksum as hex-string
• STRING: FILE='str'/STREAM/DUMMY - File which contains Checksum as hex-string
  • STREAM - Read from stdin or write to stdout
  • DUMMY - Read EOF or write nothing
