unix - tc shell script: undefined variable -

-

can tell me doing wrong set flag1.. getting error of flag1: undefined variable.

if($notloaded1 > 0)   echo "rows not loaded due data errors in first load: $notloaded1"   set flag1=1 endif  if($notloaded2 > 0)   echo "rows not loaded due data errors in second load: $notloaded2"   set flag2=1 endif  if($notloaded3 > 0)   echo "rows not loaded due data errors in third load: $notloaded3"   set flag3=1 endif  echo $flag1 echo $flag2 echo $flag3

is there way check 3 of them in 1 if statement or rather using 3 if statements

if ($flag1 > 0)   exit 1 endif  if ($flag2 > 0)   exit 1 endif  if ($flag3 > 0)   exit 1 endif

thank you

what need 3 flag variables for?

set error=0  if ($notloaded1 > 0)   echo "rows not loaded due data errors in first load: $notloaded1"   set error=1 endif  if ($notloaded2 > 0)   echo "rows not loaded due data errors in second load: $notloaded2"   set error=1 endif  if ($notloaded3 > 0)   echo "rows not loaded due data errors in third load: $notloaded3"   set error=1 endif  if ($error)   exit 1 endif

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
