Try:

Code:
 awk '/^ATOM/ { v=substr($0,23,4) } END{print v}' file

To replace values try:
Code:
awk -vF=27 -vT=28 '/^ATOM/&&substr($0,23,4)+0==F{$0=substr($0,1,22) sprintf("%4d",T) substr($0,27)}1' file

NAME
dminfo - report information about a device entry in a device maps file SYNOPSIS
dminfo [-v] [-a] [-f pathname] dminfo [-v] [-a] [-f pathname] -n dev -name... dminfo [-v] [-a] [-f pathname] -d dev -path... dminfo [-v] [-a] [-f pathname] -t dev -type... dminfo [-v] [-f pathname] -u dm -entry DESCRIPTION
dminfo reports and updates information about the device_maps(4) file. OPTIONS
The following options are supported -a Succeed if any of the requested entries are found. If used with -v, all entries that match the requested case(s) are printed. -d dev-path Search by dev-path. Search device_maps(4) for a device special pathname in the device_list field matching the dev-path argument. This option cannot be used with -n, -t or -u. -f pathname Use a device_maps file with pathname instead of /etc/security/device_maps. -n dev-name Search by dev-name. Search device_maps(4) for a device_name field matching dev-name. This option cannot be used with -d, -t or -u. -t dev-type Search by dev-type. Search device_maps(4) for a device_type field matching the given dev-type. This option cannot be used with -d, -n or -u. -u dm-entry Update the device_maps(4) file. This option is provided to add entries to the device_maps(4) file. The dm-entry must be a complete device_maps(4) file entry. The dm-entry has fields, as in the device_maps file. It uses the colon (:) as a field separator, and white space as the device_list subfield separators. The dm-entry is not made if any fields are missing, or if the dm-entry would be a duplicate. The default device maps file can be updated only by the super user. -v Verbose. Print the requested entry or entries, one line per entry, on the standard output. If no entries are specified, all are printed. EXIT STATUS
0 Successful completion. 1 Request failed. 2 Incorrect syntax. FILES
/etc/security/device_maps ATTRIBUTES
