Thread: select waveform with sac

Dear Xuzhang -

SAC is reading input from the shell script, not your terminal. It is probably giving an end-of-file to the REPLY function.
Use a review procedure structured like this:

# Define sac macro called /tmp/view.m
cat << 'EOF' > /tmp/view.m
message "Processing $1$"
read $1$
setbb resp "(reply Enter t to trash the file)"
if _%resp% eq _t
sc mv $1$ Trash
endif
'EOF'
# Create sac input file
ls *.SAC | awk '{print "m /tmp/view.m",$1}' > /tmp/sac.in
# Run SAC once, process all files
sac
qdp off
ygrid on
message "Many questions about files will happen now ..."
m /tmp/sac.in
quit

Hello everyone,
I met a question to select waveform with sac. I hope I can check the waveform and save some good data in a folder or put bad data in another folder. The following is the part of my shell script.
for fil in *.SAC
do
sac <<ENDD
qdp off
ygrid on
r AA.SAC
p1
setbb resp (REPLY "Enter t to trash the file ")
if %resp eq "t" then
sc mv AA.SAC Trash
endif
q
ENDD
done
After excuting the shell script, there was no any pause and just put the *.SAC into the Trash folder. What' s problem in my script and how to solve it.
Thank you.
Cheers, Xuzhang
