Operating Systems HP-UX Difference between [condition] and [[condition]] and ((condition)) when used with if condition Post 302520345 by methyl on Friday 6th of May 2011 01:03:21 PM
Old 05-06-2011
Within "man sh-posix" see the section on "Conditonal Expressions" for the explanation of conditions within [[ ]] .
See "man test" for an explanation of "Test" within [ ] .
Though there is some common syntax between a "Conditional Expression" and a "Test" there is also much syntax which is exclusive. For example the AND and OR operators are quite different.
As far as I know, there is no ">" operator.

I have never found use for (( )) as an Arithmetic Test and cannot comment. Others may have seen it used.


BEWARE. The ">" sign you are using is not valid syntax. Your test scripts may not be doing what you expect.
Quote:
if [ 234 > 71 ];then
echo "correct"
else
echo "wrong"
fi
The above script creates a FILE called "71" and the "if" test is "true" because this process worked.
Suggest you check all your examples for this problem and check the directory list after each try!

Test::Fixme(3pm)					User Contributed Perl Documentation					  Test::Fixme(3pm)

NAME
Test::Fixme - check code for FIXMEs. SYNOPSIS
# In a test script like 't/test-fixme.t' use Test::Fixme; run_tests(); # You can also tailor the behaviour. use Test::Fixme; run_tests( where => 'lib', # where to find files to check match => 'TODO', # what to check for skip_all => $ENV{SKIP} # should all tests be skipped ); DESCRIPTION
When coding it is common to come up against problems that need to be addressed but that are not a big deal at the moment. What generally happens is that the coder adds comments like: # FIXME - what about windows that are bigger than the screen? # FIXME - add checking of user priviledges here. Test::Fixme allows you to add a test file that ensures that none of these get forgotten in the module. Arguments By default run_tests will search for 'FIXME' in all the files it can find in the project. You can change these defaults by using 'where' or 'match' as follows: run_tests( where => 'lib', # just check the modules. match => 'TODO' # look for things that are not done yet. ); where Specifies where to search for files. This can be a scalar containing a single directory name, or it can be a listref containing multiple directory names. match Expression to search for within the files. This may be a simple string, or a qr//-quoted regular expression. For example: match => qr/[T]ODO|[F]IXME|[B]UG/, filename_match Expression to filter file names. This should be a qr//-quoted regular expression. For example: match => qr/.(:pm|pl)$/, would only match .pm and .pl files under your specified directory. HINTS
If you want to match something other than 'FIXME' then you may find that the test file itself is being caught. Try doing this: run_tests( match => 'TO'.'DO' ); You may also wish to suppress the tests - try this: use Test::Fixme; run_tests( skip_all => $ENV{SKIP_TEST_FIXME} ); You can only run run_tests once per file. Please use several test files if you want to run several different tests. SEE ALSO
