<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Hi All,</div><div><br></div><div>Is it possible to assign a <span style="font-weight: bold; font-style: italic;">stdout </span>to a <span style="font-style: italic; font-weight: bold;">string </span>variable in Swift ? <br></div><div><br></div><div>I need to get the IP of a machine by executing an shell script and then assign it to a string variable. Please see the sample code pasted below (Here the string variable is written to a file to verify program works correctly). But the program didn't make any progress and swift was repeatedly printing a message called "Initializing site shared directory:1" on the console.</div><div><br></div><div>Any ideas ? Is this swift code is correct ? or swift does not support this feature ? In case if swift does not support this feature, is there a way to use the stdout without writing
to a file ?</div><div><br></div><div>Thank you</div><div>Emalayan<br></div><div><br></div><div>1) Source code</div><div><br></div><div><span style="font-style: italic;">t<span style="color: rgb(0, 0, 127);">ype messagefile;</span></span><br style="font-style: italic; color: rgb(0, 0, 127);"><br style="font-style: italic; color: rgb(0, 0, 127);"><span style="font-style: italic; color: rgb(0, 0, 127);">app (string machine) get_machine (string fileName) {</span><br style="font-style: italic; color: rgb(0, 0, 127);"><span style="font-style: italic; color: rgb(0, 0, 127);"> getIP fileName stdout = machine;</span><br style="font-style: italic; color: rgb(0, 0, 127);"><span style="font-style: italic; color: rgb(0, 0, 127);">}</span><br style="font-style: italic; color: rgb(0, 0, 127);"><br style="font-style: italic; color: rgb(0, 0, 127);"><span style="font-style: italic; color: rgb(0, 0, 127);">app (messagefile t) printIP (string m)
