Hi,
I'm using AWK to try to extract data from multiple files (*.txt). The script should look for a flag that occurs at a specific position in each file and it should return the data to the right of that flag.
I should end up with one line for each file, each containing 3 columns:
Filename1.txt Data1 MoreData1
Filename2.txt Data2 MoreData2
Filename3.txt Data3 MoreData3
The trouble is, my output seems to be as follows:
Filename1.txt
Filename2.txt Data1 MoreData1
Filename3.txt Data2 MoreData2
I'm not sure what I've done wrong because I'm still struggling with the syntax and structure of AWK. Any idea what is wrong?
I'm very new to UNIX, AWK, etc. so simple language would be appreciated (if possible).
Thanks
Here's the code I have, it's in a file called "extract_data_from_files.awk":
Code:
#!/usr/bin/awk
BEGIN {
print "Starting script...";
}
{
if ( substr($0,2,3) == "UWI") # substr(s, a, b) and returns b number of
# chars from string s, starting at position a.
{
well = substr($0,11,20);
gsub(/^[ \t]+|[ \t]+$/, "", well); #trim spaces
}
if ( substr($0,2,3) == "LSR")
{
kb = substr($0,11,20);
gsub(/^[ \t]+|[ \t]+$/, "", kb); #trim spaces
}
if ( FNR == 1 || EOF ) #FNR=total lines in each file. EOF=End Of File
{
concat = FILENAME "\t\t\t" well "\t\t\t" kb; #no commas needed to separate variables
print concat;
}
}
END {
print "Ending script...";
}

innoextract(1) General Commands Manual innoextract(1)NAME
innoextract - tool to extract installers created by Inno Setup
SYNOPSIS
innoextract [-behlLqstv] [-ccolor] [-pprogress] installers ...
DESCRIPTION
innoextract is a tool that can extract installer executables created by Inno Setup.
innoextract will extract files from a installers specified on the command line.
To extract a multi-part installer with external data files, only the executable (.exe) file needs to be given as an argument to innoex-
tract.
OPTIONS -c --color [enable]
By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable color output accord-
ingly. Pass 1 or true to --color to force color output. Pass 0 or false to never output color codes.
--dump Don't convert Windows paths to UNIX paths and don't substitute variables in paths.
-e --extract
Extract all files to the current directory. This is the default action. You may only specify one of --extract , --list and --test
-h --help
Show a list of the supported options.
--language [lang]
Extract only language-independent files and files for the given language. By default all files are extracted.
--license
Show license information.
-l --list
List files contained in the installer but don't extract anything. You may only specify one of --extract , --list and --test
-L --lowercase
Convert filenames stored in the installer to lower-case before extracting.
-p --progress [enable]
By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable progress bar output
accordingly. Pass 1 or true to --progress to force progress bar output. Pass 0 or false to never show a progress bar.
-q --quiet
Less verbose output.
-s --silent
Don't output anything except errors and warnings.
-t --test
Test archive integrity but don't write any output files. You may only specify one of --extract , --list and --test
-v --version
Show the innoextract version number and supported Inno Setup versions.
LIMITATIONS
innoextract currently only supports extracting all the data. There is no support for extracting individual files, components or languages.
Included scripts and checks are not executed.
Data is always extracted to the current directory and the mapping from Inno Setup variables like the application directory to subdirecto-
ries is hard-coded.
innoextract does not check if an installer includes multiple files with the same name and will continually overwrite the destination file
when extracting.
Names for data files in multi-file installers must follow the standard naming scheme.
Encrypted installers are not supported.

No known bugs.
