Hi All,
I came across a bit of code that seems to work, even though I didn't expect it to (now that's wierd!)
#!/bin/sh
set -x
nn=15
if
then
echo "is true"
fi
The above code ends up comparing the string "nn" to number 15, but still evaluates to true. Here's the output when i run it... (1 Reply)

Hi,
This should be a simple one.
All I am doing is adding an email address to my email.
Example abc@xyz.com
I understand that the @ means arrays in PERL. So, I coded the backtick (`) to dereference it. But now I get abc`@`xyz.com
Your help is appreciated.
Thanks

Simple enough problem I think, I just can't seem to get it right.
The below doesn't work as intended, it's just a function defined in a much larger script:
CheckValues() {
for field in \

while
while(n) Tcl Built-In Commands while(n)
__________________________________________________________________________________________________________________________________________________NAME
while - Execute script repeatedly as long as a condition is met
SYNOPSIS
while test body
_________________________________________________________________DESCRIPTION
The while command evaluates test as an expression (in the same way that expr evaluates its argument). The value of the expression must a
proper boolean value; if it is a true value then body is executed by passing it to the Tcl interpreter. Once body has been executed then
test is evaluated again, and the process repeats until eventually test evaluates to a false boolean value. Continue commands may be exe-
cuted inside body to terminate the current iteration of the loop, and break commands may be executed inside body to cause immediate termi-
nation of the while command. The while command always returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the while command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
set x 0
while {$x<10} {
puts "x is $x"
incr x
}
