Dear awk users,
I am trying to use awk to match records across two moderately large CSV files. File1 is a pattern file with 173,200 lines, many of which are repeated. The order in which these lines are displayed is important, and I would like to preserve it. File2 is a data file with 456,000... (3 Replies)

strextract
strextract(1) General Commands Manual strextract(1)NAME
strextract - batch string extraction
SYNOPSIS
strextract [-p patternfile] [-i ignorefile] [-d] [source-program...]
OPTIONS
Ignore text strings specified in ignorefile. By default, the strextract command searches for ignorefile in the current working directory,
your home directory, and /usr/lib/nls.
If you omit the -i option, strextract recognizes all strings specified in the patterns file. Use patternfile to match strings in
the input source program. By default, the command searches for the pattern file in the current working directory, your home direc-
tory, and finally /usr/lib/nls.
If you omit the -p option, the strextract command uses a default patterns file that is stored in /usr/lib/nls/patterns. Disables
warnings of duplicate strings. If you omit the -d option, strextract prints warnings of duplicate strings in your source program.
DESCRIPTION
The strextract command extracts text strings from source programs. This command also writes the string it extracts to a message text file.
The message text file contains the text for each message extracted from your input source program. The strextract command names the file by
appending to the name of the input source program.
In the source-program argument, you name one or more source programs from which you want messages extracted. The strextract command does
not extract messages from source programs included using the #include directive. Therefore, you might want a source program and all the
source programs it includes on a single strextract command line.
You can create a patterns file (as specified by patternfile ) to control how the strextract command extracts text. The patterns file is
divided into several sections, each of which is identified by a keyword. The keyword must start at the beginning of a new line, and its
first character must be a dollar sign ($). Following the identifier, you specify a number of patterns. Each pattern begins on a new line
and follows the regular expression syntax you use in the regexp(3) routine. For more information on the patterns file, see the patterns(4)
reference page.
In addition to the patterns file, you can create a file that indicates strings that extract ignores. Each line in this ignore file con-
tains a single string to be ignored that follows the syntax of the regexp(3) routine.
When you invoke the strextract command, it reads the patterns file and the file that contains strings it ignores. You can specify a pat-
terns file and an ignore file on the strextract command line. Otherwise, the strextract command matches all strings and uses the default
patterns file.
If strextract finds strings which match the ERROR directive in the pattern file, it reports the strings to standard error (stderr.) but
does not write the string to the message file.
After running strextract, you can edit the message text file to remove text strings which do not need translating before running strmerge.
It is recommended that you use extract command as a visual front end to the strextract command rather than running strextract directly.
RESTRICTIONS
Given the default pattern file, you cannot cause strextract to ignore strings in comments that are longer than one line.
You can specify only one rewrite string for all classes of pattern matches.
The strextract command does not extract strings from files include with #include directive. You must run the strextract commands on these
files separately.
% strextract -p c_patterns prog.c prog2.c % vi prog.str % strmerge -p c_patterns prog.c prog2.c % gencat prog.cat prog.msg prog2.msg % vi
nl_prog.c % vi nl_prog2.c % cc nl_prog.c nl_prog2.c
In this example, the strextract command uses the c_patterns file to determine which strings to match. The input source programs are named
prog.c and prog2.c.
If you need to remove any of the messages or extract one of the created strings, edit the resulting message file, prog.str. Under no condi-
tions should you add to this file. Doing so could result in unpredictable behavior.
You issue the strmerge command to replace the extracted strings with calls to the message catalog. In response to this command, strmerge,
creates the source message catalogs, prog.msg and prog2.msg, and the output source programs, nl_prog.c and nl_prog2.c.
You must edit nl_prog.c and nl_prog2.c to include the appropriate catopen and catclose function calls.
The gencat command creates a message catalog and the cc command creates an executable program.
