Hi all,<br><br>Frequently I have used this instruction within or not of a loop:<br><br>sac << EOF<br>macro ../sac_cut.macro<br>EOF<br><br>EOF (end of file, or what ever other string) is used to identify or close the end of sac (or other program like matlab or R) intructions. Between sac<<EOF and EOF you can put sac instructions. But you must care dont put space or tabs before the onset of each line, usually done when we put code within a loop. If EOF has, for instance, 3 spaces before EOF, the open intruction of sac must have them:<br><br>sac << EOF<br>
macro ../sac_cut.macro<br>
EOF<br><br>I am using cshell. I have not tested in other type of shell. If you dont want echo of the process you can use this:<br><br>sac << EOF>/dev/null<br>
macro ../sac_cut.macro<br>
EOF<br><br>If you want extract results to a file:<br><br>sac << EOF>my.file<br>
macro ../sac_cut.macro<br>
EOF<br><br>regards,<br>P.<br><br><br><hr id="stopSpelling">Date: Mon, 25 Oct 2010 14:21:44 -0400<br>From: jattanayake@gmail.com<br>To: sac-help@iris.washington.edu<br>Subject: Re: [SAC-HELP] calling sac commands within shell scripts<br><br>Hi again, <br>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.<br>
