Top Forums Shell Programming and Scripting Export variable, as a background process Post 302447767 by Cranie on Tuesday 24th of August 2010 08:43:40 AM

I can't, the "td" command connects to the database and returns the rows. Initially I had:

Code:
export NUMROWS=`td "select * from dbc.database" 2> /dev/null | 
    grep "Query completed" | sed -e 's/.*Query completed. //g' -e 's/row.*found.*//g'`

That works. What I need is to run that in the background as it can take minutes or hours to run the SQL, if after, say in our test, 30minutes, this process is still running I want to kill it. So need the & to run in background. But without writing the results to a file can't see any obvious way of doing it...

NAME
shell - run a command using shell SYNOPSIS
shell command [command] ... DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise /usr/bin/sh). EXAMPLES
Example 1: A sample output of shell command. Since the Form and Menu Language does not directly support background processing, the shell function can be used instead. `shell "build prog > /dev/null &"` If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe- cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing. shell can also be used to execute a command that has the same name as an FMLI built-in function. NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments will not be expanded by the shell because "local" means "local to the current process." ATTRIBUTES
