-c : display changed byte

Display altered bytes at the end of any ALT line , after the Tag, "ChgBytes:"

Example:

readmin -c

Output line:

-f <filename> : specify input log file

Example:

readmin -f log.22feb17-0

-m <logid:offset:datatype>

Search the log file for Alter logs, that changed a paticular field on one type of record.

logid

logid is the control logid which you can easily find out using fdbstat.

following example show logid for STOCK is 9

fdbstat -v /u/cc/comp/stock.dat
Filename      flags  ssize/ vsize/ bucsiz/ 1stbuc/ # bucs/ lastbuc nulls log     release
                     prelen suflen keysize elsize  maxnkey lastnod ok ?  id      alphalen

stock.dat     MASTER 3072   1024   4096    2       0       1147          9       64

offset

offset is the starting byte of the field in the record. which can be found by running align on any dec files in /u/ccr.xx/std/hdrs/

use stock.dec as an example

align /u/ccr.16/std/hdrs/stock.dec

following is a cut down version of the out.

/* total size of s_vstock = 1024 */

if the field is in the sstock , or static part of the record the

offset is simply the start byte use supp_cost as as example is 124.

if the field is in the vstock, or the variable part of the record the

offset is the start byte plus the size of the static part

use l_cost as example its 4+3072 = 3076.

datatype

datatype tell the program how to read the field. it can be one of the following

t -- align datatype = TEXT and no.of byte is bigger than 1(for string, e.g. descriptions. address)
b -- align datatype = TEXT and no.of byte is 1 (for options)
s -- align datatype is one of the following BRANCHSIZE, SMLPTR, SMLDEC, UCOUNT, TYPDATE, TYPTIME or COUNT
n -- align datatype is one of the following SHTDEC, RECPTR, EXTDEC THREDEC 
d -- align datatype = LNGDEC
