I have this Korn shell script that runs via a cron entry. It runs in a loop "watching" a specific file system for files with a certain name. The file system that it is watching is an upload file system for an FTP server. When files that are the correct name come in, it takes the extension of the... (1 Reply)
I have to solve some exercises in Korn Shell, but i'm having some problems. For example:
Write a korn shell script with an alfanumeric string as argument. The script lists the file's names in the current directory that contain the given string as substring and that can be read and written.

I'm learning bash and have discovered that the shell can only work with integers and not decimals.
I'd like to run my scripts in korn to account for this, but just now, when I tried to run my script, I got an error message that said 'no such file or directory,' even though when I'm in the shell... (3 Replies)
There are 4 parameters that I have to pass from korn shell to sql script.
1) I have to check if $1 , $2 , $3 and $4 are null values or not .
How can I do that ?
2) Once its determined that these values are null (in the sense they are empty) how can I pass null values to sql script... (11 Replies)
Very new to the Korn Shell, but I've been looking up loops online and it seems this should work. I'm just trying to convert an ip range in variables $A and $B and iterate the individual ip's out to new lines. Unfortunately I get {152..155} instead of 152, 153, 154, and 155.

LEARN ABOUT PHP
echo
ECHO(3) 1 ECHO(3)echo - Output one or more stringsSYNOPSIS
void echo (string $arg1, [string $...])
DESCRIPTION
Outputs all parameters.
echo is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo (unlike some other
language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if you want
to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.
echo also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. Prior to PHP 5.4.0, this short syn-
tax only works with the short_open_tag configuration setting enabled.
I have <?=$foo?> foo.
PARAMETERS
o $arg1
- The parameter to output.
o $...
-
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
echo examples
<?php
echo "Hello World";
echo "This spans
multiple lines. The newlines will be
output as well";
echo "This spans
multiple lines. The newlines will be
output as well.";
echo "Escaping characters is done "Like this".";
// You can use variables inside of an echo statement
$foo = "foobar";
$bar = "barbaz";
echo "foo is $foo"; // foo is foobar
// You can also use arrays
$baz = array("value" => "foo");
echo "this is {$baz['value']} !"; // this is foo !
// Using single quotes will print the variable name, not the value
echo 'foo is $foo'; // foo is $foo
// If you are not using any other characters, you can just echo variables
echo $foo; // foobar
echo $foo,$bar; // foobarbarbaz
// Some people prefer passing multiple parameters to echo over concatenation.
echo 'This ', 'string ', 'was ', 'made ', 'with multiple parameters.', chr(10);
echo 'This ' . 'string ' . 'was ' . 'made ' . 'with concatenation.' . "
";
echo <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;
// Because echo does not behave like a function, the following code is invalid.
($some_var) ? echo 'true' : echo 'false';
// However, the following examples will work:
($some_var) ? print 'true' : print 'false'; // print is also a construct, but
// it behaves like a function, so
// it may be used in this context.
echo $some_var ? 'true': 'false'; // changing the statement around
?>
NOTES
Note
Because this is a language construct and not a function, it cannot be called using variable functions.
