-- Dear list members.
I am a coastal engineer who is not familiar with seismology. for my
project, I have to use SAC in order to convert recorded data of
seismometers to acceleration and velocity. as far as i found in IRIS and
other seismic communities, SAC is the only program which can do it for me.
however, after 3 days working on different version of it (Linux 64 bit and
Cygwin) I couldn't mount it. I mean I cannot run it. it makes me nervous
cause I couldn't find an step by step guide.
i have installed UBUNTU 64 bit on my PC.
in the README file in SAC directory, it is written I have to just set the
environment. but I cannot understand what is the meaning of :
For csh and tcsh, edit ~/.cshrc adding the lines
setenv SACHOME /usr/local/sac
source ${SACHOME}/bin/sacinit.csh
After saving and exiting the file, enter
source ~/.cshrc
For bash, edit ~/.bashrc adding the lines
export SACHOME=/usr/local/sac
source ${SACHOME}/bin/sacinit.sh
After saving and exiting the file, enter
source ~/.bashrc
what is did is as follows:
1-download the sac-101.5c-linux_x86_64.tar.qz
2-copy it into HOME
3-run the terminal
4-write -xzf sac-101.5c-linux_x86_64.tar.gz in the terminal (the directory
called SAC is now in the same place (HOME))
5- go inside bin directory.
6-there is 2 files SACINIT.CSH and SACINIT.sh
7-when i open those files, what I have to do? what changes I have to do in
these 2 files and other content of bin?
do I need copy
setenv SACHOME /usr/local/sac
source ${SACHOME}/bin/sacinit.csh
in it and save it? or something else? what is BASH and what I need to do
for it? what sort of command I have to write in terminal to finish the
setting environment and what I have to write to run the SAC?
please consdier that it makes me confused and I don't know what I have to
do? it is due to lack of knowledge.
is there anybody who know what I have to do? I really appreciate your help.
with my kindest regards
Ali

Hi Ali,
You can follow the instructions in the README file after
uncompressing the distribution.
Then you must define some environment variables, in your .bash_profile or .profile
file in your HOME directory.
below an example for yuur system but it is the same on Linux system
# SAC Environment variables
export SACHOME=/home/ali/sac
export PATH=$PATH:$SACHOME/bin
export SACAUX=$SACHOME/aux
export SACLIB=$SACHOME/lib/sacio.a
export SAC_USE_DATABASE=0
export SAC_PPK_LARGE_CROSSHAIRS=1
Important is the shell, in OSX i use bash shell, so you must use the same,
On Linux you have bash shell
Change the PATH of the variable according your system.
After you edit you .bash_profile or .profile,
do:
prompt> source .bash_profile
in order to set the environment variables.
Finally run sac.
HTH.
