Help with global variables

[tmf33uk]

Hi,

I am trying to concatenate the output of a while loop to a $message variable that will be printed once the loop has completed, but as it stands, it returns nothing from the inside $message variable.

I am currently not very interested in the else condition. As long as $inexistent has contained any value, I want $message to report on the list at the end. If none are listed, I will set a message to say that "Everything is hunky dory".

##################################################################
if [ ! -f ${oratab} ]
then
print "em_result=there is no oratab found in $oratab"
exit
else
awk -F":" '{ print $2 }' $oratab | while read line
do
if [ ! -f "${line}/network/admin/sqlnet.ora" ];
then
inexistent="${line}/network/admin"
route="${route} ${inexistent}, "
message="No sqlnet.ora file found in the following directories: ${route}."
else
existent=""${line}"/network/admin"
route2="${route2} ${existent}, "
message="An sqlnet.ora file was found in ${route2}"
exit
fi
done
print $message
fi
exit
#################################################################

Can anyone help with this?

Thanks in advance!

Regards,
T.

Hi

When you pipe into a compound command, it is executed as a child process.
Is impossible to set a process' environment from a child process.
Is impossible to access a process' environment after it terminates.

So instead of piping, set its input from somewhere else, like file, here document or here string :

[b]if[/b] [teal][[/teal] [teal]![/teal] -f [green][i]"${oratab}"[/i][/green] [teal]][/teal]
[b]then[/b]
  print [green][i]"em_result=there is no oratab found in $oratab"[/i][/green]
  [COLOR=chocolate]exit[/color]
[b]else[/b]
  [b]while[/b] [COLOR=chocolate]read[/color] line
  [b]do[/b]
    [b]if[/b] [teal][[/teal] [teal]![/teal] -f [green][i]"${line}/network/admin/sqlnet.ora"[/i][/green] [teal]][/teal]
    [b]then[/b]
      [navy]inexistent[/navy][teal]=[/teal][green][i]"${line}/network/admin"[/i][/green]
      [navy]route[/navy][teal]=[/teal][green][i]"${route} ${inexistent}, "[/i][/green]
      [navy]message[/navy][teal]=[/teal][green][i]"No sqlnet.ora file found in the following directories: ${route}."[/i][/green]
    [b]else[/b]
      [navy]existent[/navy][teal]=[/teal][green][i]"${line}/network/admin"[/i][/green]
      [navy]route2[/navy][teal]=[/teal][green][i]"${route2} ${existent}, "[/i][/green]
      [navy]message[/navy][teal]=[/teal][green][i]"An sqlnet.ora file was found in ${route2}"[/i][/green]
      [COLOR=chocolate]exit[/color]
    fi
  [b]done[/b] [highlight][teal]<<[/teal]ENDOFINPUT[/highlight]
[highlight][navy]$([/navy] awk -F[green][i]":"[/i][/green] [green][i]'{ print $2 }'[/i][/green] [navy]$oratab[/navy] [teal])[/teal][/highlight]
[highlight]ENDOFINPUT[/highlight]
  print [green][i]"$message"[/i][/green]
fi
[COLOR=chocolate]exit[/color]
