--help
The C++ and Java languages provides function overloading, which means that you can write many
functions with the same name (providing each takes parameters of different types). All C++ and Java
function names are encoded into a low-level assembly label (this process is known as mangling). The
1 program does the inverse mapping: it decodes (demangles) low-level names into user-level
c++filt
names so that the linker can keep these overloaded functions from clashing.
Every alphanumeric word (consisting of letters, digits, underscores, dollars, or periods) seen in the
input is a potential label. If the label decodes into a C++ name, the C++ name replaces the low-level
name in the output.
You can use

If no arguments are given,

the demangled names to the standard output. All results are printed on the standard output.
-_
-strip-underscores
On some systems, both the C and C++ compilers put an underscore in front of every name.
For example, the C name
underscore. Whether
-j
-java
Prints demangled names using Java syntax. The default is to use C++ syntax.
-n
-no-strip-underscores
Do not remove the initial underscore.
-p
-no-params
When demangling the name of a function, do not display the types of the function's parameters.
