ld.so
Dynamic linker/loader
root@kali:~# ld.so --help
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
You have invoked 'ld.so', the program interpreter for dynamically-linked
ELF programs. Usually, the program interpreter is invoked automatically
when a dynamically-linked executable is started.
You may invoke the program interpreter program directly from the command
line to load and run an ELF executable file; this is like executing that
file itself, but always uses the program interpreter you invoked,
instead of the program interpreter specified in the executable file you
run. Invoking the program interpreter directly provides access to
additional diagnostics, and changing the dynamic linker behavior without
setting environment variables (which would be inherited by subprocesses).
--list list all dependencies and how they are resolved
--verify verify that given object really is a dynamically linked
object we can handle
--inhibit-cache Do not use /etc/ld.so.cache
--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH
--glibc-hwcaps-prepend LIST
search glibc-hwcaps subdirectories in LIST
--glibc-hwcaps-mask LIST
only search built-in subdirectories if in LIST
--inhibit-rpath LIST ignore RUNPATH and RPATH information in object names
in LIST
--audit LIST use objects named in LIST as auditors
--preload LIST preload objects named in LIST
--argv0 STRING set argv[0] to STRING before running
--list-tunables list all tunables with minimum and maximum values
--list-diagnostics list diagnostics information
--help display this help and exit
--version output version information and exit
This program interpreter self-identifies as: /lib64/ld-linux-x86-64.so.2
Shared library search path:
(libraries located via /etc/ld.so.cache)
/lib/x86_64-linux-gnu (system search path)
/usr/lib/x86_64-linux-gnu (system search path)
/lib (system search path)

Machine-readable data files, shared objects and programs used by the C library for localization (l10n) and internationalization (i18n) support.
This package contains tools to generate locale definitions from source files (included in this package). It allows you to customize which definitions actually get generated. This is a space-saver over how this package used to be, with all locales generated by default. This created a package that unpacked to an excess of 30 megs.
Installed size: 15.48 MB
How to install: sudo apt install locales

Options:
--help display this message and exit

--locale-file=FILE file containing locale variables
(Default: /etc/locale.conf)
--no-checks do not perform sanity checks on locale variables
validlocale
Test if a given locale is available
root@kali:~# man validlocale
validlocale(8) validlocale(8)
NAME
validlocale - Test if a given locale is available
SYNTAX
validlocale <locale>
DESCRIPTION
Test if the locale given as argument is a valid locale. If it isn't,
print on stdout the string to add to /etc/locale.gen to make locale-gen
generate the locale (if it exists at all).
FILES
/usr/sbin/validlocale
/usr/share/i18n/SUPPORTED
ENVIRONMENT VARIABLES
DEFAULTCHARSET
Which charset to assume if the given locale is missing from the
list of supported locales.
EXAMPLES
If you give a valid locale as parameter, it outputs a string specifying
this on stderr:
% validlocale C
locale 'C' valid and available
When given a invalid (not generated or just nonexistent), it outputs a
string on stderr telling that this is an invalid locale, and a string to
stdout with the string to add to /etc/locale.gen to have this locale
generated:
% validlocale de_AU@euro
locale 'de_AU@euro' not available
de_AU@euro ISO-8859-15
