Top Forums Shell Programming and Scripting Take input from read and place it a string in another file Post 302593015 by Corona688 on Wednesday 25th of January 2012 11:42:26 AM

Why insert it? Why not just use it? This is a strange-sounding system.

You could export it, and set it only in that script if it's not already set.

Code:
# outside the script
read IPADDRESS
export IPADDRESS
./myscript

Code:
#inside myscript, set the variable if nothing else did
[ -z "$IPADDRESS" ] && IPADDRESS="default.ip.address"

That way you don't need to hack apart your scripts with sed all the time, which sounds a recipe for disaster if I ever heard one...

NAME
snmpset - communicates with a network entity using SNMP SET requests SYNOPSIS
snmpset [COMMON OPTIONS] OID TYPE VALUE [OID TYPE VALUE]... DESCRIPTION
snmpset is an SNMP application that uses the SNMP SET request to set information on a network entity. One or more object identifiers (OIDs) must be given as arguments on the command line. A type and a value to be set must accompany each object identifier. Each variable name is given in the format specified in variables(5). The TYPE is a single character, one of: i INTEGER u UNSIGNED s STRING x HEX STRING d DECIMAL STRING n NULLOBJ o OBJID t TIMETICKS a IPADDRESS b BITS Most of these will use the obvious corresponding ASN.1 type. 's', 'x', 'd' and 'b' are all different ways of specifying an OCTET STRING value, and the 'u' unsigned type is also used for handling Gauge32 values. If you have the proper MIB file loaded, you can, in most cases, replace the type with an '=' sign. For an object of type OCTET STRING this will assume a string like the 's' type notation. For other types it will do "The Right Thing". For example: snmpset -c private -v 1 test-hub system.sysContact.0 s dpz@noc.rutgers.edu ip.ipforwarding.0 = 2 will set the variables sysContact.0 and ipForwarding.0: system.sysContact.0 = STRING: "dpz@noc.rutgers.edu" ip.ipForwarding.0 = INTEGER: not-forwarding(2) If the network entity has an error processing the request packet, an error packet will be returned and a message will be shown, helping to pinpoint in what way the request was malformed. OPTIONS
snmpset takes the common options described in the snmpcmd(1) manual page. SEE ALSO
