Top Forums Shell Programming and Scripting AIX equivalent to GNU grep's -B and -A [print lines after or before matching lines] Post 302416398 by zaxxon on Monday 26th of April 2010 11:32:09 AM

In this case you might have to write something in awk for example to have a similar functionality.
Althoug there is an old version of GNUgrep in the official IBM Linux toolbox available, just in case you were allowed to install this one.

Without focus on parsing input etc., here a solution in awk how it could look like:
Code:
$> cat infile
bla 1
bla 2
bla 3
bla 4
bla 5
bla 6
bla 7
bla 8
bla 9
bla 10


$cat mach.ksh
awk -v direction="$1" -v offset="$2" -v pattern="$3" '

$0 ~ pattern {s=NR; _[NR]=$0; next}
{_[NR]=$0; next}

END{
        if( direction == "B" ){
                x=(s-offset)
                while( s >= x ){
                        print _[x]
                        x++
                }
        }
        if( direction == "A" ){
                x=(s+offset)
                while( s <= x ){
                        print _[s]
                        s++
                }
        }
}' $4

Examples:
Code:
$> ./mach.ksh B 2 'bla 5' infile
bla 3
bla 4
bla 5
$> ./mach.ksh A 4 'bla 5' infile
bla 5
bla 6
bla 7
bla 8
bla 9

NAME
Config::Model::DumpAsData - Dump configuration content as a perl data structure VERSION
version 2.021 SYNOPSIS
use Config::Model ; use Log::Log4perl qw(:easy) ; use Data::Dumper ; Log::Log4perl->easy_init($WARN); # define configuration tree object my $model = Config::Model->new ; $model ->create_config_class ( name => "MyClass", element => [ [qw/foo bar/] => { type => 'leaf', value_type => 'string' }, baz => { type => 'hash', index_type => 'string' , cargo => { type => 'leaf', value_type => 'string', }, }, ], ) ; my $inst = $model->instance(root_class_name => 'MyClass' ); my $root = $inst->config_root ; # put some data in config tree the hard way $root->fetch_element('foo')->store('yada') ; $root->fetch_element('bar')->store('bla bla') ; $root->fetch_element('baz')->fetch_with_id('en')->store('hello') ; # put more data the easy way my $step = 'baz:fr=bonjour baz:hr="dobar dan"'; $root->load( step => $step ) ; print Dumper($root->dump_as_data); # $VAR1 = { # 'bar' => 'bla bla', # 'baz' => { # 'en' => 'hello', # 'fr' => 'bonjour', # 'hr' => 'dobar dan' # }, # 'foo' => 'yada' # }; DESCRIPTION
This module is used directly by Config::Model::Node to dump the content of a configuration tree in perl data structure. The perl data structure is a hash of hash. Only CheckList content will be stored in an array ref. Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the data structure will contain 'a','b'. CONSTRUCTOR
new ( ) No parameter. The constructor should be used only by Config::Model::Node. Methods dump_as_data(...) Return a perl data structure Parameters are: node Reference to a Config::Model::Node object. Mandatory full_dump Also dump default values in the data structure. Useful if the dumped configuration data will be used by the application. (default is yes) skip_auto_write Skip node that have a "perl write" capability in their model. See Config::Model::AutoRead. auto_vivify Scan and create data for nodes elements even if no actual data was stored in them. This may be useful to trap missing mandatory values. ordered_hash_as_list By default, ordered hash (i.e. the order of the keys are important) are dumped as Perl list. This is the faster way to dump such hashed while keeping the key order. But it's the less readable way. When this parameter is 1 (default), the ordered hash is dumped as a list: [ A => 'foo', B => 'bar', C => 'baz' ] When this parameter is set as 0, the ordered hash is dumped with a special key that specifies the order of keys. E.g.: { __order => [ 'A', 'B', 'C' ] , B => 'bar', A => 'foo', C => 'baz' } Methods dump_annotations_as_pod(...) Return a string formatted in pod (See perlpod) with the annotations. Parameters are: node Reference to a Config::Model::Node object. Mandatory experience master, advanced or beginner check_list Yes, no or skip AUTHOR
