4. Shell Programming and Scripting
I know that when using 'while (<FILE>) {}', Perl reads only one line of the file at one time, and store it in '$_'.
Can I change some parameters so that 'while (<>) {}' can read more than one lines, like 2 or 5 lines at one time?
Thanks for the help! (1 Reply)

NICE(3) BSD Library Functions Manual NICE(3)
NAME
nice -- set program scheduling priority
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
nice(int incr);
DESCRIPTION
This interface is obsoleted by setpriority(2).
The nice() function obtains the scheduling priority of the process from the system and sets it to the priority value specified in incr. The
priority is a value in the range -20 to 20. The default priority is 0; lower priorities cause more favorable scheduling. Only a process
with appropriate privileges may lower priorities.
Children inherit the priority of their parent processes via fork(2).
RETURN VALUES
Upon successful completion, nice() returns the new nice value minus NZERO. Otherwise, -1 is returned, the process' nice value is not
changed, and errno is set to indicate the error.
ERRORS
The nice() function will fail if:
[EPERM] The incr argument is negative and the caller does not have appropriate privileges.
SEE ALSO
nice(1), fork(2), setpriority(2), renice(8)
STANDARDS
The nice() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'').
HISTORY
A nice() syscall appeared in Version 6 AT&T UNIX.
BSD
April 30, 2011 BSD
