Korn Shell Array maximum value less than other value
I have a text file with several key words that I am trying to isolate. I have grepped for the unknowns in the text file, but each unknown has a corresponding location. I have created an array that holds all the unknowns and another array that holds all of the locations and compares them based on the line number in the report. the locations are always before the unknowns, so I compare positions in the array to check that the location line number is less than the unknown line number. However, the problem is there are multiple locations and multiple unknowns, so if the unknown is above several locations it prints all of those locations whereas I want the closes one. Please see the code:
Output is as follows:
Output should be:

I'm attempting to populate an array in ksh using the following command:

SELECT_INVOICE is a function that executes the SQL query.

I read it is possible to provide values for an array with the -A option to the read statement; however, I have not been able to get this to work. When I execute a script with the -A option to the read statement, the shell complains that it is an illegal option. If this works, can someone provide... (5 Replies)
Hello,
I'm currently messing around with arrays for the first time in scripting (Unix Korn Shell). All I'm trying to do right now before I make things complicated is read through and print out to screen whether the read file is or is not a directory.
Here is my directory:
ls -l

I have a script that contains

but if I do this at the command prompt I am able to create it

I have a korn shell script that reads a file with just one column in the file. If the file has more than 5 entries it is split using split -5. This means that is we have 15 entries I will end up with 3 files with 5 entries/lines in each and if I have 23 entries I will end up with 5 files with the... (2 Replies)

unknown
unknown(n) Tcl Built-In Commands unknown(n)
__________________________________________________________________________________________________________________________________________________NAME
unknown - Handle attempts to use non-existent commands
SYNOPSIS
unknown cmdName ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command is invoked by the Tcl interpreter whenever a script tries to invoke a command that does not exist. The default implementation
of unknown is a library procedure defined when Tcl initializes an interpreter. You can override the default unknown to change its func-
tionality, or you can register a new handler for individual namespaces using the namespace unknown command. Note that there is no default
implementation of unknown in a safe interpreter.
If the Tcl interpreter encounters a command name for which there is not a defined command (in either the current namespace, or the global
namespace), then Tcl checks for the existence of an unknown handler for the current namespace. By default, this handler is a command named
::unknown. If there is no such command, then the interpreter returns an error. If the unknown command exists (or a new handler has been
registered for the current namespace), then it is invoked with arguments consisting of the fully-substituted name and arguments for the
original non-existent command. The unknown command typically does things like searching through library directories for a command proce-
dure with the name cmdName, or expanding abbreviated command names to full-length, or automatically executing unknown commands as sub-pro-
cesses. In some cases (such as expanding abbreviations) unknown will change the original command slightly and then (re-)execute it. The
result of the unknown command is used as the result for the original non-existent command.
The default implementation of unknown behaves as follows. It first calls the auto_load library procedure to load the command. If this
succeeds, then it executes the original command with its original arguments. If the auto-load fails then unknown calls auto_execok to see
if there is an executable file by the name cmd. If so, it invokes the Tcl exec command with cmd and all the args as arguments. If cmd
cannot be auto-executed, unknown checks to see if the command was invoked at top-level and outside of any script. If so, then unknown
takes two additional steps. First, it sees if cmd has one of the following three forms: !!, !event, or ^old^new?^?. If so, then unknown
carries out history substitution in the same way that csh would for these constructs. Finally, unknown checks to see if cmd is a unique
abbreviation for an existing Tcl command. If so, it expands the command name and executes the command with the original arguments. If
none of the above efforts has been able to execute the command, unknown generates an error return. If the global variable auto_noload is
defined, then the auto-load step is skipped. If the global variable auto_noexec is defined then the auto-exec step is skipped. Under nor-
mal circumstances the return value from unknown is the return value from the command that was eventually executed.
EXAMPLE
Arrange for the unknown command to have its standard behavior except for first logging the fact that a command was not found:
# Save the original one so we can chain to it
rename unknown _original_unknown
# Provide our own implementation
proc unknown args {
puts stderr "WARNING: unknown command: $args"
uplevel 1 [list _original_unknown {*}$args]
}
