OK I have an input file (e.g. imput.txt) which looks something like :-
Code:
Server 1 | Group 1 | 34586 | Alive
Server 2 | Group 1 | 92876 | Alive
Server 1 | Group 2 | 87321 | Alive
Server 2 | Group 2 | 18763 | Alive
Then I do :-
Code:
while read line
do
if [[ `awk -F \| '{gsub(/[[:space:]]*/,"",$4); print $4 }'` != "Alive" ]]; then
print "Server :" `awk -F\| '{print $1}'` " is " `awk -F\| '{print $4}'`
fi
done < input.txt
Now this doesn't work in that even though all servers are "Alive", the code still enters the if statement.
Hi,
Is there a way to evaluate an equation contained in a string within an AWK script?
For example:
A = "(5*2)-1" (this equation is read from a file and varies line by line)
In this example, I can't see any way to get an answer of 9 unless I do:
cmd = "awk 'BEGIN{print "A"}'"

Hello guys,
I'm actually working on my master thesis which has for subject the evaluation of virtual firewall in a cloud environment. To do so, I installed my own cloud using OpenNebula (as a frontend) and Xen (as a Node) on two different machines. The Xen machine is my virtual firewall thanks... (2 Replies)

Hello,
IBM offers a evaluation version of their XL C/C++ compiler. Unfortunatly v16.1 (from Developerworks) can not be installed on AIX 5.3 (I can not upgrade my old 32 Bit RS/6000 to a later version) and I have not found any older versions on the IBM and Developerworks pages.

Could somebody please explain to me why and how the highlighted line(s) (?) of code puts the "test" evaluation into "result" and then to $enable_static ? Or does not ?
I did comment out the original code and changed it to what I feel is less cryptic , but the "result" is still wrong =... (3 Replies)

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.
