Hi Sac Users,



Can you please help me in listing all my SAC files in increasing order of
their back-azimuth values and assigning integer weights starting from “1”
to each file in their “user8” header? If there are 8 sac files then file
with minimum back-azimuth will have "1" weight in user8, while maximum
back-azimuth file will have "8" weight in its sac header.

Thanks

    Hi Sachin,

    You can write small scripts.

    Something similar like this.

    write in sort_baz.sh file and run inside all sac file
    assume your sac file end with "*sac"*
    and run by *sh sort_baz.sh *
    #!!!!!!!!!!
    #!/bin/sh
    rm -rf baz.list
    for fname in *.*sac*
    do
    baz=`saclst BAZ f $fname | awk '{print $2}'`
    echo $fname $baz >>baz.list

    done
    cat listbaz. | sort -k2n | awk '{print NR,$1,$2}' | while read line
    do
    fln=`echo $line | awk '{print $2}'`
    num=`echo $line | awk '{print $1}'`
    sac<<!
    r $fln
    ch user8 $num
    wh
    q
    !
    done
    #!!!!!!!!!!
