I have a comma-separated record and I'd like to use sed to pull the Nth record from it.
It seems like it'd need to be something like this: sed -n 's/'"\,$1\,"'/&/p'
Am I close? (3 Replies)
does anyone have an awk one-liner to:
print the first line, the second line, then every Nth line, and the last line of a file.
Thanks,
Kenny. (5 Replies)

netsnmp::oid
OID(3) User Contributed Perl Documentation OID(3)NAME
NetSNMP::OID - Perl extension for manipulating OIDs
SYNOPSIS
use NetSNMP::OID;
my $oid = new NetSNMP::OID('sysContact.0');
if ($oid < new NetSNMP::OID('ifTable')) {
do_something();
}
my @numarray = $oid->to_array();
# appending oids
$oid = new NetSNMP::OID('.1.3');
$oid += ".6.1";
# -> .1.3.6.1
# appending index strings
$oid2 = $oid + ""wes"";
# -> .1.3.6.1.3.119.101.115
$oid3 = $oid + "'wes'";
# -> .1.3.6.1.119.101.115
$len = $oid3->length();
# -> 7
# retrieving indexes from an oid:
$arrayref = $tableoid->get_indexes()
DESCRIPTION
The NetSNMP::OID module is a simple wrapper around a C-based net-snmp oid (which is an array of unsigned integers). The OID is internally
stored as a C array of integers for speed purposes when doing comparisons, etc.
The standard logical expression operators (<, >, ==, ...) are overloaded such that lexographical comparisons may be done with them.
The + operator is overloaded to allow you to append stuff on to the end of a OID, like index segments of a table, for example.
EXPORT
int snmp_oid_compare(oid1, oid2) int compare(oid1, oid2)
