I have a set of files of multi-line records with the records separated by a blank line. I needed to add a record number to the front of each line followed by a colon and did the following:
so i would get something like:
1: XXX:CCCC:XYXYX
1: XTZ:CACC:XYXYX
1: XZZ:DDDD:XYXYX
2: XTZ:CACC:XYXYX
2: XZZ:DMMD:XYXYX
3: XZZ:DMMD:XYXYX
4: XZZ:DMMD:XYXYX
4: XVZ:DMHD:XYXYX
4: XVV:DLMD:XYXYX
4: XTZ:DCDD:XYXYX
Problem is my numbers are not coming out right. When i do a count like:
awk '{RS=""; print NR}' ~/Desktop/data98-1-25.txt > ~/Desktop/Count98-1-25.txt
I get the the number i am expecting for the last set of records in the file: 4959 but when i run the code up above for numbering each record the last set of records shows the end number as 4958. Is this one of those NR starts at zero and i started i at 1 or vice-versa type of problems; or is my code wrong to do what i was trying to do?
Another question i will have, is when i go to start processing the next file to start numbering it's records how do i get the count to start on 4960?

I'm pretty new to sed and awk, and I can't quite figure this one out. I've been trying with sed, as I'm more comfortable with it for the time being, but any tool that fits the bill will be fine.

HWDB(7) hwdb HWDB(7)NAME
hwdb - Hardware Database
DESCRIPTION
The hardware database is a key-value store for associating modalias-like keys to udev-property-like values. It is used primarily by udev to
add the relevant properties to matching devices, but it can also be queried directly.
HARDWARE DATABASE FILES
The hwdb files are read from the files located in the system hwdb directory /lib/udev/hwdb.d and the local administration directory
/etc/udev/hwdb.d. All hwdb files are collectively sorted and processed in lexical order, regardless of the directories in which they live.
However, files with identical filenames replace each other. Files in /etc have the highest priority and take precedence over files with the
same name in /lib. This can be used to override a system-supplied hwdb file with a local file if needed; a symlink in /etc with the same
name as a hwdb file in /lib, pointing to /dev/null, disables that hwdb file entirely. hwdb files must have the extension .hwdb; other
extensions are ignored.
Each hwdb file contains data records consisting of matches and associated key-value pairs. Every record in the hwdb starts with one or more
match strings, specifying a shell glob to compare the lookup string against. Multiple match lines are specified in consecutive lines. Every
match line is compared individually, and they are combined by OR. Every match line must start at the first character of the line.
The match lines are followed by one or more key-value pair lines, which are recognized by a leading space character. The key name and value
are separated by "=". An empty line signifies the end of a record. Lines beginning with "#" are ignored.
In case multiple records match a given lookup string, the key-value pairs from all records are combined. If a key is specified multiple
times, the value from the record with the highest priority is used (each key can have only a single value). The priority is higher when the
record is in a file that sorts later lexicographically, and in case of records in the same file, later records have higher priority.
The content of all hwdb files is read by systemd-hwdb(8) and compiled to a binary database located at /etc/udev/hwdb.bin, or alternatively
/lib/udev/hwdb.bin if you want ship the compiled database in an immutable image. During runtime, only the binary database is used.
EXAMPLES
Example 1. General syntax of hwdb files
# /lib/udev/hwdb.d/example.hwdb
# Comments can be placed before any records. This is a good spot
# to describe what that file is used for, what kind of properties
# it defines, and the ordering convention.
# A record with three matches and one property
mouse:*:name:*Trackball*:
mouse:*:name:*trackball*:
mouse:*:name:*TrackBall*:
ID_INPUT_TRACKBALL=1
# A record with a single match and five properties
mouse:usb:v046dp4041:name:Logitech MX Master:
MOUSE_DPI=1000@166
MOUSE_WHEEL_CLICK_ANGLE=15
MOUSE_WHEEL_CLICK_ANGLE_HORIZONTAL=26
MOUSE_WHEEL_CLICK_COUNT=24
MOUSE_WHEEL_CLICK_COUNT_HORIZONTAL=14
Example 2. Overriding of properties
# /lib/udev/hwdb.d/60-keyboard.hwdb
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn*
KEYBOARD_KEY_a1=help
KEYBOARD_KEY_a2=setup
KEYBOARD_KEY_a3=battery
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pn123*
KEYBOARD_KEY_a2=wlan
# /etc/udev/hwdb.d/70-keyboard.hwdb
# disable wlan key on all at keyboards
evdev:atkbd:*
KEYBOARD_KEY_a2=reserved
If the hwdb consists of those two files, a keyboard with the lookup string "evdev:atkbd:dmi:bvnAcer:bdXXXXX:bd08/05/2010:svnAcer:pn123"
will match all three records, and end up with the following properties:
KEYBOARD_KEY_a1=help
KEYBOARD_KEY_a2=reserved
KEYBOARD_KEY_a3=battery
