Reading specific contents from 1 input files and appending it to another input file
Hi guys,
I am new to AWK and unix scripting. Please see below my problem and let me know if anyone you can help.
I have 2 input files (example given below)
Input file 2 is a standard file (it will not change) and we have to get the name (second column after comma) from it and append it in the Input file 1 (see output file below highlighted in blue). The content of first input file Input file 1 will keep changing though.
If we get a match with first number [before first dot (.)] then concatenate the name from second file at the end with a comma (,).
Input file 1
Aug 14 10:37 123.XYZ.106.20061023160210.in
Aug 14 12:59 135.XYZ.107.20061023160210.in
Aug 14 13:15 234.XYZ.108.20061023160210.in
Input file 2
111,ABCD
123,EFGH
124,TYUI
125,RTYUGH
135,RTYT
139,REFG
234,GHJK
345,GHJK
346,JKHG
Output file
Aug 14 10:37 123.XYZ.106.20061023160210.in, EFGH
Aug 14 12:59 135.XYZ.107.20061023160210.in, RTYT
Aug 14 13:15 234.XYZ.108.20061023160210.in, GHJK
Appreciate your responses.

truncate
TRUNCATE(1) User Commands TRUNCATE(1)
NAME
truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
treat SIZE as number of IO blocks instead of bytes
-r, --reference=RFILE
base size on RFILE
-s, --size=SIZE
set or adjust the file size by SIZE bytes
--help display this help and exit
--version
output version information and exit
SIZE is an integer and optional unit (example: 10M is 10*1024*1024). Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ...
(powers of 1000).
SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round
down to multiple of, '%' round up to multiple of.
