[SAC-HELP] calling sac commands within shell scripts

[Onur Tan]

Hi ,

This Cshell script may run (I cannot test at this time) .

the file a.csh  :
----
foreach dir ( ` cat folder_list.txt ` )   #  note that there two backquotes

cd  $dir
echo macro ../sac_cut.macro   > macro.tmp    # the last line of the sac_cut.macro must be ‘exit’ to quit from sac
sac < macro.tmp
cd ..

end
\rm tmp
----

to  run type
> csh a.csh

Hi again,
I've had a couple of responses from the members, thanks for your time! However, none of them worked. I still get the same error. I am calling sac within a while read line loop. Should there be a special way of calling sac and executing commands if I do it in a loop? I haven't come across this problem with other programs like GMT and taup at all.

my error msg: SAC> readline: readline_callback_read_char() called with no handler!

and bash script:

while read line
do
    cd $line

        sac
        gawk '{print "macro ../sac_cut.macro"}'

    cd ../
done < folder_list.txt

commands I've tried so far:

       (1) echo -e "macro ../sac_cut.macro" | sac

       (2) sac << EOF and  !
            macro ../sac_cut.macro
            EOF and !      ==> doesn't work within a while loop

       (3) printf  "macro ../sac_cut.macro" | sac
       (4) echo  "macro ../sac_cut.macro" | sac


Thanks again !

Januka.

Greetings,
I am trying to call sac within a shell script as follows.

while read line
do
    cd $line

        sac
        gawk '{print "macro ../sac_cut.macro"}'

    cd ../
done < folder_list.txt


folder_list.txt holds the names of all the directory names that the script is suppose to look in.
I see that sac is initiated but the problem is in executing commands within sac once it is initiated. I have tried several ways of doing that including printf and piping to sac with back quotes. Still I get the following error.

SAC> readline: readline_callback_read_char() called with no handler!

How should one execute sac commands within a shell script?

I am using sac Version 101.3b

Thanks a lot.

Januka.
