I find it's handy to create a Log() function, to keep the messges format consistent and also allow output to several places and/or options.
I write something like:
Code:
#!/bin/ksh
# myscript
# Globals.
PROG=${0##*/}
LOGFILE=/var/tmp/mylog.txt
# Function to do logging.
Log()
{
timestamp=`date '+%Y%m%d.%H%M%s'`
echo "[$PROG.$timestamp] $*" >> $LOGFILE
}
# your code...
if [ ..... ]
then
Log "It was successful"
else
Log "Oh no!"
fi
You can then have logic in the Log function to raise OpenView alerts, send emails, write to syslog, or whatever, without having to trawl through your entire script looking at each echo command.
I have a matrix , how do I compare all the elements of a column , lets say I want to check if the columns contain the alphabets "S","H","A","R","A","T".

Yet another question. I want to make something like this:

but that apparently is not right. I want either the first condition to be true OR the second AND third conditions to be true for the "then" to be processed. How can I do this? (1 Reply)
Pardon the pseudo code below, but I'm wondering how I would do something along the lines of this...
#!/bin/sh

echo $theItem

Hi was wonderring about the syntax for the following peice of code:
while ] ; do
This is apparently incorrect. I want the loop to continue WHILE $life is not equal to zero or $mask is not equal to $word. Should ONE of these conditions fail to be met, loop should break out. Any ideas? ... (8 Replies)
Hi,

The problem is, that server is continously sending files to our server via FTP. But the observation is that some files missing in our Server but in that server it shows the files FTPed... (2 Replies)
Hi there, I have a table that stores multiple records for many different servers, each of which is timestamped ... I wanted to write a query that would enable me to only output the "latest" record (based on timestamp) for each "unique" server. So for example my main table looks like this

__________________________________________________________________________________________________________________________________________________NAME
term::ansi::ctrl::unix - Control operations and queries
SYNOPSIS
package require Tcl 8.4
package require term::ansi::ctrl::unix ?0.1?
::term::ansi::ctrl::unix::import ?ns? ?arg...?
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::columns
::term::ansi::ctrl::unix::rows
_________________________________________________________________DESCRIPTION
WARNING: This package is unix-specific and depends on the availability of two unix system commands for terminal control, i.e. stty and
tput, both of which have to be found in the $PATH. If any of these two commands is missing the loading of the package will fail.
The package provides commands to switch the standard input of the current process between raw and cooked input modes, and to query the size
of terminals, i.e. the available number of columns and lines.
API
INTROSPECTION
::term::ansi::ctrl::unix::import ?ns? ?arg...?
This command imports some or all attribute commands into the namespace ns. This is by default the namespace ctrl. Note that this is
relative namespace name, placing the imported command into a child of the current namespace. By default all commands are imported,
this can howver be restricted by listing the names of the wanted commands after the namespace argument.
OPERATIONS
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to raw input mode. This means that from then on all characters typed
by the user are immediately reported to the application instead of waiting in the OS buffer until the Enter/Return key is received.
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to cooked input mode. This means that from then on all characters
typed by the user are kept in OS buffers for editing until the Enter/Return key is received.
::term::ansi::ctrl::unix::columns
This command queries the terminal connected to the standard input for the number of columns available for display.
::term::ansi::ctrl::unix::rows
This command queries the terminal connected to the standard input for the number of rows (aka lines) available for display.
