To whom it may concern,

I am a first year graduate student at the University of Memphis for the Center for Earthquake Research and Information. I need to use SAC for my global seismology class, but I'm very new to the terminal command line and I'm having difficulty installing SAC.

Neither < tar -xzf sac-102.0-mac.tar.gz > or < gzip -d -c sac-102.0-mac.tar.gz | tar -xf - >worked for me (the command prompts provided in the email with the file) when I entered them. I had been in the directory (Downloads) when I tried them. The first prompt didn't do anything and the second put out a bunch of nonsense characters and question marks that I couldn't make heads or tails of.

Instead, I've moved my <.tar > file to my Desktop and it has made a sac subdirectory I can see on my terminal command line. However, I am still uncertain how to properly install the sac program. I would appreciate any guidance you can provide.

Sincerely,
Ryann Lam

Subject: SAC Software: Mac

Attached is a compressed tar file that contains the SAC 102.0 binary
distribution for Mac (64 bit) OSX: sac-102.0-mac.tar.gz.

Built on 10.13 with a minimum system requirement of 10.8 using the default OSX
installation Unix programs and libraries. It has been tested successfully on
10.15. If XQuartz is not already on your system, it needs to be downloaded from https://www.xquartz.org/ and installed.

The first step is to expand the .tar.gz file. You can do this in one step:

tar -xzf sac-102.0-mac.tar.gz

Alternatively, you can enter

gzip -d -c sac-102.0-mac.tar.gz | tar -xf -

The result is the creation of a subdirectory ./sac .

If you have a problem getting to this point, reply to this e-mail message with a
detailed description of your problem.

File ./sac/License, contains the terms you agreed to honor when you requested
SAC software. In particular you agreed NOT TO DISTRIBUTE the SAC Software.

Instructions for setting environmental variables for your system are given in
file ./sac/README . The information in that file should be all you need to get
the package running on your system.

    Hi Ryann,
    Simply extracting the zipped folder isn't enough. There's a file containing
    the instructions for installation in the expanded folder, which is
    straight forward. Here's an old thread from the SAC archive if you need
    additional details:
