Top Forums Shell Programming and Scripting FILE_ID extraction from file name and save it in CSV file after looping through each folders Post 302700671 by Don Cragun on Friday 14th of September 2012 12:09:03 AM

The following seems to do what you requested. You say that you want to create a CSV file, but by definition a CSV file has fields that are separated by commas. You don't show any commas in any of your sample output. This script uses a tab to separate output fields to get the headers to line up with the following data. Although it is written using ksh, it should also work with at least bash and sh:
Code:
#!/bin/ksh
printf "file_id\tfile_name\n"
find 2[0-9][0-9][0-9] -name 'sasmm_fsbc_durds_id000[0-9]*_t?*' | while read path
do
        file=$(basename "$path" .trnsfr.gz)
        id=${file#sasmm_fsbc_durds_id000}
        id=${id%%_t*}
        printf "%s\t%s\n" "$id" "$file"
done

Note that this will ignore any files found in and under the year directories that don't match your filename specifications.

To run it, save the above code in a file (e.g., extract) in the same directory where the year directories reside, make it executable by issuing the command:
Code:
chmod +x extract

and then issue the command:
Code:
./extract > output_file

If you leave off > output_file, the output will be written to your terminal. If you want to save the output in a file with a name other than output_file, replace it with any name you want.

Text::CSV::Encoded::Coder::EncodeGuess(3pm)		User Contributed Perl Documentation	       Text::CSV::Encoded::Coder::EncodeGuess(3pm)

NAME
Text::CSV::Encoded::Coder::EncodeGuess - Text::CSV::Encoded coder class using Encode::Guess SYNOPSIS
use Text::CSV::Encoded coder_class => 'Text::CSV::Encoded::Coder::EncodeGuess'; use Spreadsheet::ParseExcel; my $csv = Text::CSV::Encoded->new(); $csv->encoding( ['ucs2', 'ascii'] ); # guessing ucs2 or ascii? $csv->encoding_to_combine('shiftjis'); my $excel = Spreadsheet::ParseExcel::Workbook->Parse( $file ); my $sheet = $excel->{Worksheet}->[0]; for my $row ( $sheet->{MinRow} .. $sheet->{MaxRow} ) { my @fields; for my $col ( $sheet->{MinCol} .. $sheet->{MaxCol} ) { my $cell = $sheet->{Cells}[$row][$col]; push @fields, $cell->{Val}; } $csv->combine( @fields ) or die; print $csv->string, " "; } DESCRIPTION
This module is inherited from Text::CSV::Encoded::Coder::Encode. USE
Except for 2 attributes, same as Text::CSV::Encoded::Coder::Encode. encoding_in $csv = $csv->encoding_in( $encoding_list_ref ); The accessor to an encoding for pre-parsing CSV strings. If no encoding is given, returns current $encoding, otherwise the object itself. $encoding_list_ref = $csv->encoding_in() When you pass a list reference, it might guess the encoding from the given list. $csv->encoding_in( ['shiftjis', 'euc-jp', 'iso-20022-jp'] ); If it cannot guess the encoding, the first encoding of the list is used. encoding $csv = $csv->encoding( $encoding_list_ref ); $encoding_list_ref = $csv->encoding(); You can pass a list reference to this attribute only: * For list data consumed by combine(). * For list reference returned by getline(). In other word, in "combine" and "print", it might guess an encoding for the passing list data. If it cannot guess the encoding, the first encoding of the list is used. SEE ALSO
