[SAC-HELP] 3 questions

[andreas wessel]

Hi there,

for the first problem I would try to write a script that edits just one file
at a time. Then one could run that script in a for loop for all files..

something like
for j in *.sac; do
"script" $j
done

or something similar..


ps: can you please not send 2.5 kilometers of old text with your mails :)
