3. UNIX for Dummies Questions & Answers
I'm coming from a c-shell environment where I was spoiled with the tab completion on the command line, only to find that using korn-shell I don't have this capability. The only thing I can find by googling is to use 'set filec' - but that doesn't work (and I think is only for c-shell anyway).

NICE(2) Linux Programmer's Manual NICE(2)
NAME
nice - change process priority
SYNOPSIS
#include <unistd.h>
int nice(int inc);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
nice(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE
DESCRIPTION
nice() adds inc to the nice value for the calling process. (A higher nice value means a low priority.) Only the superuser may specify a
negative increment, or priority increase. The range for nice values is described in getpriority(2).
RETURN VALUE
On success, the new nice value is returned (but see NOTES below). On error, -1 is returned, and errno is set appropriately.
ERRORS
EPERM The calling process attempted to increase its priority by supplying a negative inc but has insufficient privileges. Under Linux the
CAP_SYS_NICE capability is required. (But see the discussion of the RLIMIT_NICE resource limit in setrlimit(2).)
CONFORMING TO
SVr4, 4.3BSD, POSIX.1-2001. However, the Linux and (g)libc (earlier than glibc 2.2.4) return value is nonstandard, see below. SVr4 docu-
ments an additional EINVAL error code.
NOTES
SUSv2 and POSIX.1-2001 specify that nice() should return the new nice value. However, the Linux syscall and the nice() library function
provided in older versions of (g)libc (earlier than glibc 2.2.4) return 0 on success. The new nice value can be found using getprior-
ity(2).
Since glibc 2.2.4, nice() is implemented as a library function that calls getpriority(2) to obtain the new nice value to be returned to the
caller. With this implementation, a successful call can legitimately return -1. To reliably detect an error, set errno to 0 before the
call, and check its value when nice() returns -1.
