This thread today reminded me of it: Larger window
This is OSX 10.13.6 and greater centric only.
This expands the terminal window on the fly in bash.
You initially need to put the standard terminal window to the top left hand side as far as it goes.
I wrote this for my 19 month old grandson, (17-06-2018), as he loves punching the computer keyboard.
It is a simple keyboard plaything that prints a coloured squared in a random position inside an expanded terminal window. The window size is for a MBP 13 inch device so that is the reason for the odd terminal size.
If the first argument is set to [Yy] then a single alpha-numeric character is spoken so little one can learn said characters as well as printing the random coloured square. If the second argument is set to [Yy] then you can write a sentance of not more than 40 characters to aid in speech learning also with the random coloured square.
If there are no arguments then just the random coloured square is generated per keystroke.
Have fun little ones.

Hi
I would like to test for a max number value. It may be a decimal so I know I have to pipe into bc.
I just cannot get the syntax for this to work. I cannot get passed an error with the bracket - see below.
Any help appreciated.

Hello All,
I am trying to come up with a shell script to count a specific word in a logfile on each day of this month, last month and the month before. I need to produce this report and email it to customer.
Any ideas would be appreciated! (5 Replies)
Hi,
I have a script that accepts an input date from the user in yyyy-mm-dd format.
I need to get the mm-dd part and convert it to month name.
example:
2011-11-15
I want that to become "Nov 15"
I don't have the GNU date, I am using an AIX os.
Thanks. (1 Reply)

random
RANDOM(3) Linux Programmer's Manual RANDOM(3)NAME
random, srandom, initstate, setstate - random number generator.
SYNOPSIS
#include <stdlib.h>
long int random(void);
void srandom(unsigned int seed);
char *initstate(unsigned int seed, char *state, size_t n);
char *setstate(char *state);
DESCRIPTION
The random() function uses a non-linear additive feedback random number generator employing a default table of size 31 long integers to
return successive pseudo-random numbers in the range from 0 to RAND_MAX. The period of this random number generator is very large, approx-
imately 16*((2**31)-1).
The srandom() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned by random(). These
sequences are repeatable by calling srandom() with the same seed value. If no seed value is provided, the random() function is automati-
cally seeded with a value of 1.
The initstate() function allows a state array state to be initialized for use by random(). The size of the state array n is used by init-
state() to decide how sophisticated a random number generator it should use -- the larger the state array, the better the random numbers
will be. seed is the seed for the initialization, which specifies a starting point for the random number sequence, and provides for
restarting at the same point.
The setstate() function changes the state array used by the random() function. The state array state is used for random number generation
until the next call to initstate() or setstate(). state must first have been initialized using initstate() or be the result of a previous
call of setstate().
RETURN VALUE
The random() function returns a value between 0 and RAND_MAX. The srandom() function returns no value. The initstate() and setstate()
functions return a pointer to the previous state array, or NULL on error.
ERRORS
EINVAL A state array of less than 8 bytes was specified to initstate().
NOTES
Current "optimal" values for the size of the state array n are 8, 32, 64, 128, and 256 bytes; other amounts will be rounded down to the
nearest known amount. Using less than 8 bytes will cause an error.
