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.

    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.
