Using a bash for loop to pass variables into a nawk loop to capture a string in an sftp log. Tried several different syntax methods to have the variable treated as a regex so the loop will capture the string.
The contents of /tmp/dar3.out.2 are all sftp session log ID's.
Is it possible to make the search in regular exprecion or in matching parts of sed, nawk and others to IGNORE the case of the search string?
I mean, like if used 'grep' with -i option:
> grep -i "abc" file
I would like to be able to do the same, say, by nawk:
> nawk '/abc/ {print $0}'... (4 Replies)

Hi again,
I'm looking for some help with nawk, I can print a line which has a regex match in it from a file using /pattern/ but I'm looking for a way to only print the $tring which contains the pattern, rather than the whole line.
This $tring may be of variable length, may occur at any point... (1 Reply)
I have a scripting problem that I'm trying to solve, whereby I want to match that a string contains either of three strings. I'm thinking this is probably just me not understanding how to craft the appropriate regex. However, here's what I would like to do:

I have a file with the contents below "lets say the name of the file is abcxyz" shown at the end of this.

I stumbled upon a problem, which I simplified to this:

There is a number that should be compared against this list. For demonstration I use user input - read VALUE

io::async::pid
IO::Async::PID(3pm) User Contributed Perl Documentation IO::Async::PID(3pm)NAME
"IO::Async::PID" - event callback on exit of a child process
SYNOPSIS
use IO::Async::PID;
use POSIX qw( WEXITSTATUS );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $kid = $loop->fork(
code => sub {
print "Child sleeping..
";
sleep 10;
print "Child exiting
";
return 20;
},
);
print "Child process $kid started
";
my $pid = IO::Async::PID->new(
pid => $kid,
on_exit => sub {
my ( $self, $exitcode ) = @_;
printf "Child process %d exited with status %d
",
$self->pid, WEXITSTATUS($exitcode);
},
);
$loop->add( $pid );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits.
For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data
to and receiving data from it.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_exit $exitcode
Invoked when the watched process exits.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
pid => INT
The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object.
on_exit => CODE
CODE reference for the "on_exit" event.
Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object.
METHODS
$process_id = $pid->pid
Returns the underlying process ID
$pid->kill( $signal )
Sends a signal to the process
