Some of my scripts have very long commands that go beyond the horizontal scroll limits of my screen (1024 x 768), even with a very small font. Is there a continuation character (like the option+l "ell") in AppleScript that will let me break up the line?
Right now I just press a hard return to... (2 Replies)
I have written a basic fetching script. The script logs into an FTP site, downloads a .zip file, then unzips and moves the files to the necessary folders, then deletes them, etc.
The problem I have is if one of the files no longer exists on the FTP site or another part of the script fails, then... (3 Replies)
Hello. I'm trying to write a script to take a 5 field file, do some math, and extend it to 9 fields. Problem is, the script keeps wrapping it to two lines, even tho 9 fields, tab separated (even comma separated) doesn't fill the screen. Even if it did, I'm eventually copying it to an excel ...

Hello everyone...
I need to find out, how to find longest line or possibly lines in several files which are arguments for script. The thing is, that I tried some possibilities before, but nothing worked correctly.
Example
when i use:
awk ' { if ( length > L ) { L=length ;s=$0 } }END{ print... (23 Replies)
I am using the echo command to send the output to the file.
I am using the following code:
echo "service started successfully\n" > log
But when I do:
cat log
I get:
service started successfully\n
Instead of a newline after the "successfully"
Why is that and how can I fix it? (3 Replies)
Why does echo supress line breaks in bash?
I'm working on a script that starts like this:
words=`sort list.txt | uniq`
echo $words | wc -l
I need to number the lines and then do other stuff. I'd use jot, but it's not installed, so I hope I can get seq to do what I want. But first I need to... (2 Replies)

I'm working on a new exercise that calls for a script that will take in two arguments on the command line (representing the range of line numbers) and will subsequently print those lines from a a specified file. Command line would look like this: ./lines_script.bash 5 15 <file.txt. The script would... (8 Replies)
I can not figure out how to capture the $filename variable store by the bash.

I am parsing a log with this format:
06:36:12.230 details here
06:36:12.250 details here
06:36:12.260 details here
continuation here
06:36:12.360 details here
As you can see, some detail info contains one or more "\n" and it breaks my line-oriented parsing.
I need to get those... (3 Replies)

io::async::protocol::linestream
IO::Async::Protocol::LineStream(3pm) User Contributed Perl Documentation IO::Async::Protocol::LineStream(3pm)NAME
"IO::Async::Protocol::LineStream" - stream-based protocols using lines of text
SYNOPSIS
Most likely this class will be subclassed to implement a particular network protocol.
package Net::Async::HelloWorld;
use strict;
use warnings;
use base qw( IO::Async::Protocol::LineStream );
sub on_read_line
{
my $self = shift;
my ( $line ) = @_;
if( $line =~ m/^HELLO (.*)/ ) {
my $name = $1;
$self->invoke_event( on_hello => $name );
}
}
sub send_hello
{
my $self = shift;
my ( $name ) = @_;
$self->write_line( "HELLO $name" );
}
This small example elides such details as error handling, which a real protocol implementation would be likely to contain.
DESCRIPTION EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_read_line $line
Invoked when a new complete line of input is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_read_line => CODE
CODE reference for the "on_read_line" event.
METHODS
$lineprotocol->write_line( $text )
Writes a line of text to the transport stream. The text will have the end-of-line marker appended to it; $text should not end with it.
