[SAC-HELP] writing blackboard and header values to ascii

[Kris Walker]

Hi Dylan,

It's been awhile since I used SAC, but a workaround for the header  
values is to write to an ascii file using "write alpha test.txt",  
then execute a unix command to grab from that new file header the  
values you want and redirect them to another ascii file like this "sc  
sed -n 2p test.txt | awk '{print $3}' > valued_data.txt && rm -rf  
test.txt".  A kludge, but this approach will work.  One thing about  
this though, you have to figure out how to escape SAC interpretation  
of certain characters.  I forget the escape sequence(s) required to  
make that command work from within SAC.  You could also however write  
a shell script that essentially is this line, then call that shell  
script with the sc command from within SAC instead, after the alpha  
write.  Good luck.
