Don,
Again, part of my confusion is me not interpreting your questions properly. Initially (#5), I was not sure what was the best way to sort/merge file1 and file2. I knew what result I needed (as I showed in output examples throughout), but I was still trying to figure out which time field would be better to sort on since these files are extracted from a binary file into a readable csv. Apparently the time fields "G_CCSDS_DOY,G_CCSDS_DOY(RAW),G_CCSDS_MSEC,G_CCSDS_MSEC(RAW),G_CCSDS_USEC,G_CCSDS_USEC(RAW)", contain the the actual timestamp (could range from 16-24 fields/columns) during process, however, the extraction tool converts it into a readable time and places it in field 1 (TIMEFORMATTED field). It appears now that field 1 time is not the best way to sort since it stops at seconds and even though the time may appear equal between the two files, they really are not when looking at milliseconds.
I uploaded my newest file1.txt and file2.txt files along with the files post "tail" command that you requested (file1_tail and file2_tail).
Take a look and see what you think, however, I fully understand if you need to abort this forum topic with me due to the lack of pertinent explainations and data I have provided. You guys have been more than helpful, Thank you!
Hi, i've two files (file1, file2) i want to take value (in column1) and search in file2 if the they match print the value from file2.
this is what i have so far.

FILENAME=="file2"
{print $0}

I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.

I have a file containing texts and indexes. I need the text between (and including ) INDEX and number "1" alone in line. I have managed this:
awk '/INDEX/,/1$/{if (!/1$/)print}' file1.txt
It works for all indexes.
And then I have second file with years and indexes per year, one per line... (3 Replies)

I have two files.
File 1 is a two-column index file, e.g.

comp11084_c0_seq3:201-539(-) comp12746_c0_seq2:191-529(+)

I am trying to use awk to find all the $2 values in file2 which is ~30MB and tab-delimited, that are between $2 and $3 in file1 which is ~2GB and tab-delimited.
I have just found out that I need to use $1 and $2 and $3 from file1 and $1 and $2of file2 must match $1 of file1 and be in the range... (6 Replies)
This is a question that is related to one I had last August when I was trying to sort/merge two files by millsecond time column (in this case column 6).

join
JOIN(1) BSD General Commands Manual JOIN(1)NAME
join -- relational database operator
SYNOPSIS
join [-a file_number | -v file_number] [-e string] [-o list] [-t char] [-1 field] [-2 field] file1 file2
DESCRIPTION
The join utility performs an ``equality join'' on the specified files and writes the result to the standard output. The ``join field'' is
the field in each file by which the files are compared. The first field in each line is used by default. There is one line in the output
for each pair of lines in file1 and file2 which have identical join fields. Each output line consists of the join field, the remaining
fields from file1 and then the remaining fields from file2.
The default field separators are tab and space characters. In this case, multiple tabs and spaces count as a single field separator, and
leading tabs and spaces are ignored. The default output field separator is a single space character.
Many of the options use file and field numbers. Both file numbers and field numbers are 1 based, i.e., the first file on the command line is
file number 1 and the first field is field number 1. The following options are available:
-a file_number
In addition to the default output, produce a line for each unpairable line in file file_number.
-e string
Replace empty output fields with string.
-o list
The -o option specifies the fields that will be output from each file for each line with matching join fields. Each element of list
has either the form file_number.field, where file_number is a file number and field is a field number, or the form '0' (zero), repre-
senting the join field. The elements of list must be either comma (',') or whitespace separated. (The latter requires quoting to
protect it from the shell, or, a simpler approach is to use multiple -o options.)
-t char
Use character char as a field delimiter for both input and output. Every occurrence of char in a line is significant.
-v file_number
Do not display the default output, but display a line for each unpairable line in file file_number. The options -v 1 and -v 2 may be
specified at the same time.
-1 field
Join on the field'th field of file1.
-2 field
Join on the field'th field of file2.
When the default field delimiter characters are used, the files to be joined should be ordered in the collating sequence of sort(1), using
the -b option, on the fields on which they are to be joined, otherwise join may not report all field matches. When the field delimiter char-
acters are specified by the -t option, the collating sequence should be the same as sort(1) without the -b option.
If one of the arguments file1 or file2 is '-', the standard input is used.
EXIT STATUS
The join utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
For compatibility with historic versions of join, the following options are available:
-a In addition to the default output, produce a line for each unpairable line in both file1 and file2.
-j1 field
Join on the field'th field of file1.
-j2 field
Join on the field'th field of file2.
-j field
Join on the field'th field of both file1 and file2.
-o list ...
Historical implementations of join permitted multiple arguments to the -o option. These arguments were of the form
file_number.field_number as described for the current -o option. This has obvious difficulties in the presence of files named 1.2.
These options are available only so historic shell scripts do not require modification and should not be used.

The join command conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
