Thank you very much 47shailesh. I have tried the code you provided me and I am still not getting correct results. I got this error message while script was executing syntax error on line 1, teletype which I believe have to do with the bc command. Also, I am getting results with newer files that should not be removed.
This script was given to me to fix. I am a mainframe programmer with very little unix experience. The whole idea for this script is we have a text file with file names (like CM.WM449M.P010.M01.PREMMAST.M1007) and retention period in months. For this file, the period is 36 months.
I need to use the text files with the file names and retention period and match each file name with the directory where the actual files reside. If there is a match on the file name, then need to check how old the file is, if it is older than the retention period, for the above example, 36 months (1098 days), I need to move it to different folder so we can free up space. Does that make sense? Any help would be greatly appreciated.

Not sure what the use of all_files variable, later checking and storing if the filename is older than retention, which is dependent on incorrect value of period.
Then checking if nonempty filename exist greater than retention then store some info in file else store some other info in additional files. Do you need log of what files were deleted ?
There is no code to delete the obsolete file.
once the script displays right results replace ls {} with rm {}
Hi,
I'm the new user of linux/unix. Can I ask that anybody know how to use the linux/unix shortcut key to search a specific file from a list of directory?

Encode::Guess -- Guesses encoding from data
SYNOPSIS
# if you are sure $data won't contain anything bogus
use Encode;
use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
my $utf8 = decode("Guess", $data);
my $data = encode("Guess", $utf8); # this doesn't work!
# more elaborate way
use Encode::Guess;
my $enc = guess_encoding($data, qw/euc-jp shiftjis 7bit-jis/);
ref($enc) or die "Can't guess: $enc"; # trap error this way
$utf8 = $enc->decode($data);
# or
$utf8 = decode($enc->name, $data)
ABSTRACT
Encode::Guess enables you to guess in what encoding a given data is encoded, or at least tries to.
DESCRIPTION
By default, it checks only ascii, utf8 and UTF-16/32 with BOM.
use Encode::Guess; # ascii/utf8/BOMed UTF
To use it more practically, you have to give the names of encodings to check (suspects as follows). The name of suspects can either be
canonical names or aliases.
CAVEAT: Unlike UTF-(16|32), BOM in utf8 is NOT AUTOMATICALLY STRIPPED.
# tries all major Japanese Encodings as well
use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
If the $Encode::Guess::NoUTFAutoGuess variable is set to a true value, no heuristics will be applied to UTF8/16/32, and the result will be
limited to the suspects and "ascii".
Encode::Guess->set_suspects
You can also change the internal suspects list via "set_suspects" method.
use Encode::Guess;
Encode::Guess->set_suspects(qw/euc-jp shiftjis 7bit-jis/);
Encode::Guess->add_suspects
Or you can use "add_suspects" method. The difference is that "set_suspects" flushes the current suspects list while "add_suspects"
adds.
use Encode::Guess;
Encode::Guess->add_suspects(qw/euc-jp shiftjis 7bit-jis/);
# now the suspects are euc-jp,shiftjis,7bit-jis, AND
# euc-kr,euc-cn, and big5-eten
Encode::Guess->add_suspects(qw/euc-kr euc-cn big5-eten/);
Encode::decode("Guess" ...)
When you are content with suspects list, you can now
my $utf8 = Encode::decode("Guess", $data);
Encode::Guess->guess($data)
But it will croak if:
o Two or more suspects remain
o No suspects left
So you should instead try this;
my $decoder = Encode::Guess->guess($data);
On success, $decoder is an object that is documented in Encode::Encoding. So you can now do this;
my $utf8 = $decoder->decode($data);
On failure, $decoder now contains an error message so the whole thing would be as follows;
my $decoder = Encode::Guess->guess($data);
die $decoder unless ref($decoder);
my $utf8 = $decoder->decode($data);
guess_encoding($data, [, list of suspects])
You can also try "guess_encoding" function which is exported by default. It takes $data to check and it also takes the list of
suspects by option. The optional suspect list is not reflected to the internal suspects list.
my $decoder = guess_encoding($data, qw/euc-jp euc-kr euc-cn/);
die $decoder unless ref($decoder);
my $utf8 = $decoder->decode($data);
# check only ascii, utf8 and UTF-(16|32) with BOM
my $decoder = guess_encoding($data);
CAVEATS
o Because of the algorithm used, ISO-8859 series and other single-byte encodings do not work well unless either one of ISO-8859 is the
only one suspect (besides ascii and utf8).
use Encode::Guess;
# perhaps ok
my $decoder = guess_encoding($data, 'latin1');
# definitely NOT ok
my $decoder = guess_encoding($data, qw/latin1 greek/);
The reason is that Encode::Guess guesses encoding by trial and error. It first splits $data into lines and tries to decode the line
for each suspect. It keeps it going until all but one encoding is eliminated out of suspects list. ISO-8859 series is just too
successful for most cases (because it fills almost all code points in x00-xff).
o Do not mix national standard encodings and the corresponding vendor encodings.
# a very bad idea
my $decoder
= guess_encoding($data, qw/shiftjis MacJapanese cp932/);
The reason is that vendor encoding is usually a superset of national standard so it becomes too ambiguous for most cases.
o On the other hand, mixing various national standard encodings automagically works unless $data is too short to allow for guessing.
# This is ok if $data is long enough
my $decoder =
guess_encoding($data, qw/euc-cn
euc-jp shiftjis 7bit-jis
euc-kr
big5-eten/);
o DO NOT PUT TOO MANY SUSPECTS! Don't you try something like this!
my $decoder = guess_encoding($data,
Encode->encodings(":all"));
It is, after all, just a guess. You should alway be explicit when it comes to encodings. But there are some, especially Japanese,
environment that guess-coding is a must. Use this module with care.
TO DO
Encode::Guess does not work on EBCDIC platforms.
