I am trying to import compressed files using a pipe on a server, IBM AIX UNIX 3.4, with very little disk space
The command is:
nohup cat xaa xab xac xad xae xaf xag | uncompress - > imp_pip &
Then the imp_pip file is used in the import statement, files=imp_pip
Does this statement... (0 Replies)
I'm trying to delete files that were created/modified in the year 2005 that we compressed and have the .Z extension on them. I tried using the awk utility but the syntax is incorrect. I don't know how to use a wildcard to capture all the compressed files. Here's the code I used

Hi there,
not sure if I am in the right place but here is my question.
I have a file that is over 100mb and my host does not allow FTP of files above 100mb so I thought I would use a compression utility to compress it into smaller parts say 10mb each, upload them and then re-assemble them on... (7 Replies)

Hi Folks,
I have a tar.gz compressed file with me, and I want to know the number of files in the archive without uncompressing it.
Please let me know how I can achieve it.

Hello everybody,
I've seen some text documents where they publish blocks of text and tell you to save it as "file.tgz" for example, and when you decompress the file, it actually works.
How is that done? is there a program?
Because i tried cat and doesn't work, tried less, more, hexedit and... (2 Replies)
I have a large number (50,000) of pretty large compressed files and I need only certain lines of data from them (each relevant line contains a certain key word). Each file contains 300 such lines. The individual file names are indexed by file number (file_name.1, file_name.2, ... ,... (1 Reply)
All,
The bottom line is that im reading a file, storing it as variables, recursively grep searching it, and then piping it to allow word counts as well. I am unsure on how to open any .zip .tar and .gzip, search for keywords and return results.
Any help would be much appreciated!
Thanks (6 Replies)
I have many compressed files I want to search using awk and want to print some file contents along with the filename it came from on each output record (I simplified awk command).

archive::zip::memberread
Archive::Zip::MemberRead(3) User Contributed Perl Documentation Archive::Zip::MemberRead(3)NAME
Archive::Zip::MemberRead - A wrapper that lets you read Zip archive members as if they were files.
SYNOPSIS
use Archive::Zip;
use Archive::Zip::MemberRead;
$zip = Archive::Zip->new("file.zip");
$fh = Archive::Zip::MemberRead->new($zip, "subdir/abc.txt");
while (defined($line = $fh->getline()))
{
print $fh->input_line_number . "#: $line
";
}
$read = $fh->read($buffer, 32*1024);
print "Read $read bytes as :$buffer:
";
DESCRIPTION
The Archive::Zip::MemberRead module lets you read Zip archive member data just like you read data from files.
METHODS
Archive::Zip::Member::readFileHandle()
You can get a "Archive::Zip::MemberRead" from an archive member by calling "readFileHandle()":
my $member = $zip->memberNamed('abc/def.c');
my $fh = $member->readFileHandle();
while (defined($line = $fh->getline()))
{
# ...
}
$fh->close();
Archive::Zip::MemberRead->new($zip, $fileName)
Archive::Zip::MemberRead->new($zip, $member)
Archive::Zip::MemberRead->new($member)
Construct a new Archive::Zip::MemberRead on the specified member.
my $fh = Archive::Zip::MemberRead->new($zip, 'fred.c')
setLineEnd(expr)
Set the line end character to use. This is set to
by default except on Windows systems where it is set to
. You will only need
to set this on systems which are not Windows or Unix based and require a line end different from
. This is a class method so call as
"Archive::Zip::MemberRead"->"setLineEnd($nl)"
rewind()
Rewinds an "Archive::Zip::MemberRead" so that you can read from it again starting at the beginning.
input_record_separator(expr)
If the argument is given, input_record_separator for this instance is set to it. The current setting (which may be the global $/) is
always returned.
input_line_number()
Returns the current line number, but only if you're using "getline()". Using "read()" will not update the line number.
close()
Closes the given file handle.
buffer_size([ $size ])
Gets or sets the buffer size used for reads. Default is the chunk size used by Archive::Zip.
getline()
Returns the next line from the currently open member. Makes sense only for text files. A read error is considered fatal enough to
die. Returns undef on eof. All subsequent calls would return undef, unless a rewind() is called. Note: The line returned has the
input_record_separator (default: newline) removed.
getline( { preserve_line_ending => 1 } )
Returns the next line including the line ending.
read($buffer, $num_bytes_to_read)
Simulates a normal "read()" system call. Returns the no. of bytes read. "undef" on error, 0 on eof, e.g.:
$fh = Archive::Zip::MemberRead->new($zip, "sreeji/secrets.bin");
while (1)
{
$read = $fh->read($buffer, 1024);
die "FATAL ERROR reading my secrets !
" if (!defined($read));
last if (!$read);
# Do processing.
....
}
