Thread: Error in SAC macro command bound within bash script

Dear Riddhi Dave -

Where’s the macro? Thats a file that is invoked with SAC’s “macro”
command (abbreviated “m”). What you are showing is command line input to
SAC.

If you want to avoid this message, put your SAC commands into a file and
then invoke that as a macro. Try:

cat << EOF > /tmp/runmacro

xlim off
cut off

r *BHZ*
synch r on
ch evla $EVLA evlo $EVLO evdp $EVDP
#change O for different event
ch O gmt $year $jday $hour $min $sec $msec
setbb otime &1,O
evaluate to cotime %otime * (-1.0)
ch ALLT %cotime IZTYPE IO
wh
if &1,DELTA NE 1.0
interp d 1.0
w over
endif
#p1
w over
quit
EOF

and then run SAC like this:
echo ‘m /tmp/runmacro’ | sac

or like this:
sac /tmp/runmacro

One way gives SAC a single command to run the macro, and the other runs
the macro as a startup file.

Hi,

I’m working on SAC macro within the bounds of a bash script.
Following is a portion of my script

#!/bin/bash
tail event_info > temp
year=`awk '{print substr($1,1,4)}' < temp `
jday=`awk '{print substr($1,5,3)}' < temp `
hour=`awk '{print substr($2,1,2)}' < temp`
min=`awk '{print substr($2,3,2)}' < temp`
sec=`awk '{print substr($2,5,2)}' < temp `
msec=`awk '{print $2}' < temp | awk -F. '{print $2}' `
EVLA=`awk '{print $3}' < temp `
EVLO=`awk '{print $4}' < temp `
EVDP=`awk '{print $5}' < temp `

rm -f temp

sac <<EOF

xlim off
cut off

r *BHZ*
synch r on
ch evla $EVLA evlo $EVLO evdp $EVDP
#change O for different event
ch O gmt $year $jday $hour $min $sec $msec
setbb otime &1,O
evaluate to cotime %otime * (-1.0)
ch ALLT %cotime IZTYPE IO
wh
if &1,DELTA NE 1.0
interp d 1.0
w over
endif
#p1
w over
quit
EOF



However, I keep getting this error:
ERROR 1017: Illegal macro command: 'if' can only be used within a macro
ERROR 1017: Illegal macro command: 'endif' can only be used within a macro


I am unable to see how that portion of my script isn’t within the SAC
macro. I would really appreciate an insight in this error.
