TGAMMA(3) BSD Library Functions Manual TGAMMA(3)NAME
tgamma, lgamma, gamma -- gamma and log of gamma
SYNOPSIS
#include <math.h>
double
tgamma(double x);
float
tgamma(float x);
double
lgamma(double x);
float
lgamma(float x);
double
gamma(double x);
DESCRIPTION
tgamma() calculates the gamma function of x. lgamma() calculates the natural logorithm of the absolute value of the gamma function of x.
gamma() is the same function as tgamma. Its use is deprecated.
SPECIAL VALUES
tgamma(+-0) returns +-infinity and raises the "divide-by-zero" floating-point exception.
tgamma(x) returns a NaN and raises the "invalid" floating-point exception if x is a negative integer.
tgamma(-infinity) returns a NaN and raises the "invalid" floating-point exception.
tgamma(+infinity) returns +infinity.
tgamma(x) generates a domain error if x is a negative integer or if the result cannnot be respresented when x is 0.
A range error may occur if the magnitude of x is too large or too small.
gamma() has the same behavior as tgamma()
lgamma(1) returns +0.
lgamma(2) returns +0.
lgamma(x) returns +infinity and raises the "divide-by-zero" floating-point exception if x is a negative integer or 0.
lgamma(+-infinity) returns +infinity.
lgamma(x) generates a range error if x is too large.
A range error may occur if x is a negative integer or 0.
SEE ALSO math(3)STANDARDS
The tgamma() , tgammf() , lgamma() , and lgammaf() functions conform to ISO/IEC 9899:1999(E).

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
ââWord FinderÂŽ Plusâ˘
12FX009:5 dpontius$ rm... (29 Replies)
