Hi
I need to be search a file of fixed length records and when I hit a particular record that match a search string, substitute a known position field
In the example file below

Hi,
How to output the duplicate record to another file. We say the record is duplicate based on a column whose position is from 2 and its length is 11 characters.
The file is a fixed width file.

Hi,
I have a fixed width text file without any header row. One of the columns contains a date in YYYYMMDD format.
If the original file contains 3 dates, I want my shell script to split the file into 3 small files with data for each date.
I am a newbie and need help doing this. (14 Replies)

I have a fixed with file with header & trailer length having the same length of the detail record file.
The details record length of this file is 24, for Header and Trailer the records will be padded with spaces to match the record length of the file
Currently I am adding 3 spaces in header... (14 Replies)
Input eg:
Ouput Expected.
The #rd line had the unexpted new line, which need to be replaced with space.
I was planing to go with checking the length of each line using awk and if the length is less than the defeined limit, (12 in above case) will replace the newline with space.

All,
I used to use following command to replace specific location in a fixed width file.
Recently looks like my command stopped working as intended. We are on AIX unix.
awk 'function repl(s,f,t,v)
{ return substr(s,1,f-1) sprintf("%-*s", t-f+1, v) substr(s,t+1) }
NR<=10 {... (3 Replies)
Hi All,
I am trying to select the rows in a fixed width file based on values in the columns.
I want to select only the rows if column position 3-4 has the value AB

file::type::builder
File::Type::Builder(3) User Contributed Perl Documentation File::Type::Builder(3)NAME
File::Type::Builder - parse mime-magic and generate code
SYNOPSIS
my $build = File::Type::Builder->new();
while (<magic>) {
chomp;
my $parsed = $build->parse_magic($_);
my $code = $build->string_start($parsed);
(or string_offset or beshort)
}
DESCRIPTION
Reads in the mime-magic file format and translates it to code. (This documentation would be longer if I really expected anyone other than
me to run the code.)
METHODS
new
Creates a new File::Type::Builder object.
parse_magic
Pulls apart a line of a mime-magic file using a string of regular expressions.
An example mime-magic file can be found in cleancode CVS at http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1
<http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1>
string
Builds code to match magic that's of type string.
Has to do some cleverness to make the regular expression work properly.
be
Builds code to match 'beshort' and 'belong' magic (eg audio/mpeg, image/jpeg).
PRIVATE METHODS
_substr_matching
Sometimes the data is smaller than the offset we're looking for in the file. If this is the case, then the file is obviously not of that
type, and furthermore we should avoid issuing a couple of warnings that Perl would otherwise emit.
This subroutine generates this code.
_get_escapes
Returns a reference to a hash defining characters that should not be escaped.
TODO
* Add handlers for other magic types (bedate, byte, etc)
* Make verbosity/logging nicer.
* Find more edge cases.
* Remove redundant 'if (length $data > 0)' check.
Longer term:
* Fix for multiple magic format types?
BUGS
Incomplete. Some known issues with odd entries in mime-magic. Skips some mime-magic lines.
