Thanks Klashxx
Can you explain what this means.
awk -F'|' '$2 !~ /^abc$/' input_file.txt > output_file.txt
does !~ means equal to? i thought its not equal to?

mosy(8) System Manager's Manual mosy(8)
NAME
mosy - The managed object syntax compiler.
SYNOPSIS
/usr/sbin/mosy [-d] [-i] [-o output_file] [-s] [-1] input_file
OPTIONS
Specifies no duplicate entries in the output file. By default, if duplicate entries exist in the input file, they will also exist in the
output file. Specifies that errors are ignored. This option causes the mosy program to create an output file even if it encounters errors.
The default behavior is that the mosy program generates no output file when errors are encountered. Specifies the file to create for mosy
output. If not specified, the output file is derived from the input file name by replacing the suffix with or appending input_file is not
specified (or is specified as a hyphen (-) for standard input), output goes to standard output.
You can also use a hyphen (-) to specify the output file name, which means output to standard out. Indicates silent mode which
turns off the default behavior of printing out objects names, type names, and identifiers. Specifies that the mosy program will
perform only the first validation pass when compiling. The mosy program prints the input_file contents as it parses, which is useful
when debugging syntax errors.
OPERANDS
Specifies a text file in MIB format describing a set of managed objects. If you do not specify an input_file or specify a hyphen (-), the
program accepts input from standard input.
DESCRIPTION
The mosy program reads a description of an SNMP-managed objects module (extracted from a MIB) and produces a simple ASCII file containing
equivalent definitions. The output file is used by various management applications. In particular, mosy output files are used as input to
the snmpi program when developing extensible SNMP subagents for Tru64 UNIX.
The input_file is typically obtained by cleaning up an RFC file that defines a MIB. (You can use the /usr/examples/esnmp/mib_converter.sh
script to perform this task.)
For a complete description of using mosy and developing subagents refer to the Network Programmer's Guide.
EXAMPLES
Compile the file chess.my with the output going to the file chess.defs. # mosy chess Clean up the MIB defined in RFC1514.txt and compile
it, placing the output in file fred.objects # /usr/examples/esnmp/mib-converter.sh < rfc1514.txt > rfc1514.my # /usr/sbin/mosy -o
fred.objects rfc1514.my
You must copy the /usr/examples/esnmp/mib-converter.sh program to another directory and make it executable in order to perform this
operation.
