Return code of background process
Hi,

I have a process that I run in the background that looks like this

Code:
${BASEDIR}/ksh/sqler.ksh   ${compnames003[$i]} &

and I would like to get the return code of the sqler.ksh script.

so my code is like this

Code:
${BASEDIR}/ksh/sqler.ksh   ${compnames003[$i]} &

retcode=$?

but this always returns 0 becuase the last statment it run was the & so is there a way to get the return code of the sqler script rather than the return code of the background process.

If I remove the background processing it works..

so

Code:
${BASEDIR}/ksh/sqler.ksh   ${compnames003[$i]}

retcode=$?

works but its not running in the background

Thanks
