There's something to be said for both [[ ... ]] and && || and something against.
Personally I prefer [ ... ] and quotes where needed, and an if [ ... ]; then else where the && part could itself fail.
[[ ]] is testing the test, and leaves you not knowing necessarily why the inner test failed. Was the condition false? Was the variable not declared when it should have been?

Hello,
I'm currently messing around with arrays for the first time in scripting (Unix Korn Shell). All I'm trying to do right now before I make things complicated is read through and print out to screen whether the read file is or is not a directory.
Here is my directory:
ls -l

Hi,
The logic is very simple but I can't seem to make this work in Korn shell.
I need to check two files to make sure there is no errors. Each of the file will have number. For example, first file btt.txt will have 112 which is good. Second file bgg.txt will have 6 which is also good. If I... (4 Replies)

Hi All
I have writing a Korn Shell script to execute it on many of our servers. But some servers don't have Korn Shell installed, they use Borne Shell.
Some operations like calculation don't work :

Is it possible to activate Korn Shell... (3 Replies)

Mail::SpamAssassin::Plugin::Shortcircuit(3pm) User Contributed Perl Documentation Mail::SpamAssassin::Plugin::Shortcircuit(3pm)NAME
Mail::SpamAssassin::Plugin::Shortcircuit - short-circuit evaluation for certain rules
SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::Shortcircuit
report Content analysis details: (_SCORE_ points, _REQD_ required, s/c _SCTYPE_)
add_header all Status "_YESNO_, score=_SCORE_ required=_REQD_ tests=_TESTS_ shortcircuit=_SCTYPE_ autolearn=_AUTOLEARN_ version=_VERSION_"
DESCRIPTION
This plugin implements simple, test-based shortcircuiting. Shortcircuiting a test will force all other pending rules to be skipped, if
that test is hit. In addition, a symbolic rule, "SHORTCIRCUIT", will fire.
Recomended usage is to use "priority" to set rules with strong S/O values (ie. 1.0) to be run first, and make instant spam or ham
classification based on that.
CONFIGURATION SETTINGS
The following configuration settings are used to control shortcircuiting:
shortcircuit SYMBOLIC_TEST_NAME {ham|spam|on|off}
Shortcircuiting a test will force all other pending rules to be skipped, if that test is hit.
Recomended usage is to use "priority" to set rules with strong S/O values (ie. 1.0) to be run first, and make instant spam or ham
classification based on that.
To override a test that uses shortcircuiting, you can set the classification type to "off".
on Shortcircuits the rest of the tests, but does not make a strict classification of spam or ham. Rather, it uses the default score
for the rule being shortcircuited. This would allow you, for example, to define a rule such as
body TEST /test/
describe TEST test rule that scores barely over spam threshold
score TEST 5.5
priority TEST -100
shortcircuit TEST on
The result of a message hitting the above rule would be a final score of 5.5, as opposed to 100 (default) if it were classified as
spam.
off Disables shortcircuiting on said rule.
spam
Shortcircuit the rule using a set of defaults; override the default score of this rule with the score from
"shortcircuit_spam_score", set the "noautolearn" tflag, and set priority to "-100". In other words, equivalent to:
shortcircuit TEST on
priority TEST -100
score TEST 100
tflags TEST noautolearn
ham Shortcircuit the rule using a set of defaults; override the default score of this rule with the score from
"shortcircuit_ham_score", set the "noautolearn" and "nice" tflags, and set priority to "-100". In other words, equivalent to:
shortcircuit TEST on
priority TEST -100
score TEST -100
tflags TEST noautolearn nice
shortcircuit_spam_score n.nn (default: 100)
When shortcircuit is used on a rule, and the shortcircuit classification type is set to "spam", this value should be applied in place
of the default score for that rule.
shortcircuit_ham_score n.nn (default: -100)
When shortcircuit is used on a rule, and the shortcircuit classification type is set to "ham", this value should be applied in place of
the default score for that rule.
TAGS
The following tags are added to the set available for use in reports, headers etc.:
_SC_ shortcircuit status (classification and rule name)
_SCRULE_ rulename that caused the shortcircuit
_SCTYPE_ shortcircuit classification ("spam", "ham", "default", "none")
