Programming logic help

Hi,

I was having a problem regarding this thread:

HTML Code:

https://www.unix.com/shell-programming-scripting/225221-setting-variable-using-variables-loop.html

I have not been able to solve that issue. So i was thinking maybe my logic to solve the overall problem is wrong, so i am looking for a bit of help on what would be a good way to approach the following task.

I have a list of 24 files that are produced daily. On some days all 24 files may not be produced. The filenames are in the format filename-2digitnumber ( e.g. log-01). In each of the files, i need to search for an occurrence of a particular word and see how many times it occurs. Once i have the occurrences per file, i then need to total up all the occurrences per file into a grand total.

The way i have gone about this was to do a for loop, which had an if statement within it which did a check to see if the file existed. Then I would do a count on the file and assign it to a variable, that is also a variable. I get stuck at this stage as in the above thread. Code example:

Code:

file=log

for i in 01 02 03; do
if [ -f $file-$i ]; then
count$i=`grep -c word $file-$i`
fi
done

for i in 01 02 03; do 
if [ ! -z "$count$i" ]; then
:
else Tcount=`expr $Tcount + $count$i`
fi
done

Any ideas on how to go about this will be appreciated.

Thanks

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
