Question Using 'defaults read' and storing the output in a variable

Hi all,

I'm creating a script which uses 'defaults read' to retrieve details from an Info.plist like this;

defaults read "/Path/Contents/Info" CFBundleShortVersionString

This works fine in Terminal and returns the expected values.

Is it possible to use this command in a script, and store the output into a variable?

Many thanks in advance Smilie

Dave

NAME
SNMP::Info::Layer2 - SNMP Interface to network devices serving Layer2 only. AUTHOR
Max Baker SYNOPSIS
# Let SNMP::Info determine the correct subclass for you. my $l2 = new SNMP::Info( AutoSpecify => 1, Debug => 1, DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost. "; my $class = $l2->class(); print "SNMP::Info determined this device to fall under subclass : $class "; # Let's get some basic Port information my $interfaces = $l2->interfaces(); my $i_up = $l2->i_up(); my $i_speed = $l2->i_speed(); foreach my $iid (keys %$interfaces) { my $port = $interfaces->{$iid}; my $up = $i_up->{$iid}; my $speed = $i_speed->{$iid} print "Port $port is $up. Port runs at $speed. "; } DESCRIPTION
This class is usually used as a superclass for more specific device classes listed under SNMP::Info::Layer2::* Please read all docs under SNMP::Info first. Provides abstraction to the configuration information obtainable from a Layer2 device through SNMP. Information is stored in a number of MIBs. For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above. my $l2 = new SNMP::Info::Layer2(...); Inherited Classes SNMP::Info SNMP::Info::Bridge SNMP::Info::Entity Required MIBs Inherited Classes MIBs required by the inherited classes listed above. MIBs can be found in netdisco-mibs package. GLOBALS
These are methods that return scalar value from SNMP Overrides $l2->model() Cross references $l2->id() with product IDs in the Cisco MIBs. For HP devices, removes 'hpswitch' from the name For Cisco devices, removes c<'sysid'> from the name $l2->vendor() Tries to discover the vendor from $l2->model() and $l2->description() $l2->serial() Returns serial number if available through SNMP Globals imported from SNMP::Info See documentation in "GLOBALS" in SNMP::Info for details. Globals imported from SNMP::Info::Bridge See documentation in "GLOBALS" in SNMP::Info::Bridge for details. Globals imported from SNMP::Info::Entity See documentation in "GLOBALS" in SNMP::Info::Entity for details. TABLE METHODS
These are methods that return tables of information in the form of a reference to a hash. Overrides $l2->interfaces() Creates a map between the interface identifier (iid) and the physical port name. Defaults to "ifDescr" but checks and overrides with "ifName" $l2->i_ignore() Returns reference to hash. Increments value of IID if port is to be ignored. Ignores ports with "ifType" of loopback, propvirtual, other, and cpu Table Methods imported from SNMP::Info See documentation in "TABLE METHODS" in SNMP::Info for details.
