by default, each of your three recipe lines is running in its own subshell.
thus the export in first line is not seen by subsequent lines. if you end each command with a semi-colon and a backslash followed by your neline, then the three commands will execute in the same subshell. see: http://www.gnu.org/software/make/manual/html_node/Execution.html and http://www.gnu.org/software/make/manual/html_node/Splitting-Lines.html#Splitting-Lines you might prefer an "&&" instead of a ";" if you want to stop execution after the first command that fails. ~ [email protected] ________________________________________ From: [email protected] [[email protected]] on behalf of Jack Bates [[email protected]] Sent: Thursday, August 29, 2013 10:34 AM To: [email protected] Subject: Output of one recipe in arguments to subsequent recipes? Is there any way to use the standard output of one command (recipe) in arguments to subsequent recipes? How would you approach something like the following (which doesn't work): > school: > export HOST=$$(php /usr/share/cacti/cli/add_device.php \ > --description=school \ > --ip=172.23.0.1 \ > --template=1 | sed -n 's/Success - new device-id: (\([0-9]\+\))/\1/p') > > php /usr/share/cacti/cli/add_tree.php \ > --type=node \ > --node-type=host \ > --tree-id=$$DEFAULT_TREE \ > --host-id=$$HOST > > php /usr/share/cacti/cli/add_graphs.php \ > --graph-type=ds \ > --graph-template-id=$$TRAFFIC \ > --host-id=$$HOST \ > --snmp-query-id=$$INTERFACE_STATISTICS \ > --snmp-query-type-id=$$IN_OUT_BITS \ > --snmp-field=ifOperStatus \ > --snmp-value=Up I want to assign the standard output to the HOST variable and then use that in arguments to subsequent commands. I guess the above doesn't work because variables from one recipe aren't propagated to subsequent recipes, but is there any way to do it correctly?
