Hi,
I have a file that looks like this (tab seperated):
read - DFHJ
read1 - IOPE
read2 + AAAB
read3 + MMMN
Basically what i want to do is reverse column 3 if column 2 has a - but leave it if its +
so the output would look like this:
read - JHFD
read1 - EPOI
read2 + AAAB... (3 Replies)
Hello, I am new to awk and I was wandering if I could reverse line and word order from a text file using awk. I figured out how to do them both separately, but can't quite figure out how to mix them.
Example:

1 2 3
I am new to awk
Output of the awk program:... (3 Replies)
My input is:
hello how are you
my chemistry book is lost
what is up

I found an earlier response to a similar question but it was not accurate as it required a certain string length for each line (2 Replies)

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.
