You are not allowed to put relative paths in LD_LIBRARY_PATH. That is a very insecure thing to do.

Hello,
I'm wondering what is the naming conventions for *.so shared libraries in linux. For example, a library in /lib, say libcrypt-2.7.so has a symbolic link called libcrypt.so.1 pointing to it, yet libncursesw.so.5.6 has a symbolic link called libncursesw.so.5 pointing to it. What is the... (2 Replies)

pm_which
PM_WHICH(1p) User Contributed Perl Documentation PM_WHICH(1p)
NAME
pm_which - find installed modules
SYNOPSIS
pm_which [ options ] module(s)
Returns the path to the given module(s)
OPTIONS
-q, --quiet Just print paths
-p, --paths Just convert the module name into a relative path
-a, --all Print all paths, not just the first one found
-n, --namespace Print all modules in the given namespace
-m Only print module names, not paths
-V Show module version
-I libpath Add a path to search (like perl -I)
-d, --dump Dump paths that would be searched (@INC by default)
-h, --help Print this message
-v, --version Print version information
- Read modules from stdin, one per line
DESCRIPTION
This tool reports the locations of installed perl modules.
By default it lists the location of each specified module that would be loaded by require.
OPTION DETAILS
quiet
Under quiet mode, module names are suppressed and missing modules are not reported.
Normal output:
$ pm_which Module::One Module::Two Missing::Module
Module::One - /path/to/Module/One.pm
Module::Two - /path/to/Module/Two.pm
Missing::Module - not found
Under --quiet:
$ pm_which -q Module::One Module::Two Missing::Module
/path/to/Module/One.pm
/path/to/Module/Two.pm
paths
In "paths" mode, each module is simply converted into a relative file path. This is possible even when the module is not installed.
$ pm_which -p Missing::Module
Missing/Module.pm
all
When the "all" switch is specified, all installed modules will be reported, not just the first one. This is useful for determining when
there is a module installed in multiple locations.
$ pm_which -a MyModule
/path/to/MyModule.pm
/home/me/perl/MyModule.pm
namespace
Arguments are taken as namespaces to search under.
$ pm_which -n MyModule
MyModule - /path/to/MyModule.pm
MyModule::Foo - /path/to/MyModule/Foo.pm
MyModule::Foo::Bar - /path/to/MyModule/Foo/Bar.pm
-m
Disables printing of module paths. This is only really useful in conjunction with --namespace.
$ pm_which -nm MyModule
MyModule
MyModule::Foo
MyModule::Foo::Bar
-V
Prints the version of each module, according to ExtUtils::MakeMaker.
$ pm_which -V MyModule
MyModule - /path/to/MyModule.pm [ 1.00 ]
$ pm_which -Vnm MyModule
MyModule [ 1.00 ]
MyModule::Foo [ 0.01 ]
MyModule::Foo::Bar [ undef ]
dump
Dumps the paths that would be searched and exits. This is @INC modified by any -I switches.
$ pm_which --dump
/usr/lib/perl5/site_perl/5.8.6
/usr/lib/perl5/vendor_perl/5.8.6
...
$ pm_which -I lib --dump -I blib/lib
lib
blib/lib
/usr/lib/perl5/site_perl/5.8.6
...
version
Prints the version number of the script, plus the version and path of Module::Util that was loaded.
EXIT CODES
o 0 - Everything was OK
o 1 - Initialisation failed (bad switches?)
o 2 - Some modules were not installed
SEE ALSO
This utility comes with Module::Util.
