UCSB Biogeography Laboratory FTP Help
What format are those files ending in ".gz" in?
Some of the data on our FTP
archive have been compressed with gzip. Gzip
is a public domain compression
program available for unix, ms-dos and mac platforms which
is similar in behavior to the unix "compress/uncompress"
You can obtain
your own copy of gzip
for your particular machine type from our archive, or
read up on gzip first.
What is "tar" format?
Tar is an archive program which allows the grouping of several
files into a single file. It is similar in nature to pkzip for MS-DOS
machines, but without the compression. If a file from our site ends in ".tar"
it needs to have its files extracted from it. Tar is most often
found on unix platforms, but we have
MS-DOS and macs.
What do I do when a file ends in ".tar.gz"?
When a file ends in ".tar.gz" it is a gzip compressed tar file.
First uncompress it with gzip, then extract it from the archive with tar.
On my unix machine, I could type
gzip -dc FILE.tar.gz | tar xvf -
to decompress and extract the contents from the tar file in
