WIP2

Table of Contents Previous Section Next Section Archive Command, tar

The tar command on Linux is often used to create .tar.gz or .tgz archive files (may be referred to as "tarballs"). The GNU tar command included with Linux distributions has integrated compression. It can create a .tar archive and then compress it with gzip or bzip2 compression in a single command. This is why the resulting file is a .tar.gz file or .tar.bz2 file.

Table of Contents Previous Section Next Section Company Overview

SIMOTIME Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SIMOTIME has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions or need assistance with converting non-relational data structures simply give us a call at 415 883-6565 or check the web site at http://www.simotime.com
