I'm working on a script to send emails with logs attached based on one single rule..."check if the number of errors has increased since the last time the script ran"
Basically what my script does is read from a previous file with the last trace of errors the previous error count, read the main log file to see if more errors has came out since the last time and compare those values. If the current count are greater than the previous one, then collect the logs and send them by email, here is the code:
When I run this script this throws me this output:
So my concern here is that '>' is not a valid identifier for boolean expressions, or do I need to fix something else?
Any help will be highly appreciate.
Best Regards

let
let(1) User Commands let(1)NAME
let - shell built-in function to evaluate one or more arithmetic expressions
SYNOPSIS
ksh
let arg...
ksh93
let [expr...]
DESCRIPTION
ksh
Each arg is a separate arithmetic expression to be evaluated.
ksh93
let evaluates each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...)) syn-
tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.
EXIT STATUS
ksh
ksh returns the following exit values:
0 The value of the last expression is non-zero.
1 The value of the last expression is zero.
ksh93
ksh93 returns the following exit values:
0 The last expr evaluates to a non-zero value.
>0 The last expr evaluates to 0 or an error occurred.
