reading lines from a file between two search patterns
Hi,
I am new to shell scripting and is working on a script to extract lines from a log file between two time stamps using awk command. After some research I used following command:
This works fine. But now i want to convert the hard coded dates to variable and have following command, but that does not work. I do not see any error message either
Any help on this would be greatly appreciated. If you think there is a better way of doing this then please suggest.
I have one file:
123*100*abcd*10
123*101*abcd*-29*def
123*100*abcd*-10
123*102*abcd*-105*asd
I would like to parameterize the search patterns in the following way so that the user could dynamically change the search pattern.
*100* and *- (ie *minus)
*102* and *-
The output that is... (6 Replies)

I have a file say for ex. file1 which has 3500 lines in it which are different account numbers and another file (file2) which has 230000 lines in it. I want to read all the lines in file1 and delete all those lines from file2 which has that same pattern as in file1. I am not quite... (4 Replies)
Hi everyone,
I am trying to retrieve certain log from a big file. The log size can be from 200 - 600 lines. I have 3 search patterns, out of which 2 (first and last lines) search patterns are common for all the transactions but 3rd search pattern (occurs in the middle of transaction) is... (5 Replies)

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
