The histogram scale is logaritmic, to avoid very short bars for smaller files or very long bars for bigger files.

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(1) BSD General Commands Manual NICE(1)
NAME
nice -- execute a utility with an altered scheduling priority
SYNOPSIS
nice [-n increment] utility [argument ...]
DESCRIPTION
nice runs utility at an altered scheduling priority. If an increment is given, it is used; otherwise an increment of 10 is assumed. The
super-user can run utilities with priorities higher than normal by using a negative increment. The priority can be adjusted over a range of
-20 (the highest) to 20 (the lowest). A priority of 19 or 20 will prevent a process from taking any cycles from others at nice 0 or better.
Available options:
-n increment
A positive or negative decimal integer used to modify the system scheduling priority of utility.
EXIT STATUS
The nice utility exits with one of the following values:
1-125 An error occurred in the nice utility.
126 The utility was found but could not be invoked.
127 The utility could not be found.
Otherwise, the exit status of nice will be that of utility.
COMPATIBILITY
The historic -increment option has been deprecated but is still supported in this implementation.
SEE ALSO
csh(1), getpriority(2), setpriority(2), renice(8)
STANDARDS
The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
HISTORY
A nice utility appeared in Version 6 AT&T UNIX.
BUGS
nice is built into csh(1) with a slightly different syntax than described here. The form 'nice +10' nices to positive nice, and 'nice -10'
can be used by the super-user to give a process more of the processor.
