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.

I want that to become "Nov 15"
I don't have the GNU date, I am using an AIX os.
Thanks. (1 Reply)

echo
echo(1) User Commands echo(1)NAME
echo - echo arguments
SYNOPSIS
/usr/bin/echo [string]...
DESCRIPTION
The echo utility writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. If there are no arguments,
only the NEWLINE character is written.
echo is useful for producing diagnostics in command files, for sending known data into a pipe, and for displaying the contents of environ-
ment variables.
The C shell, the Korn shell, and the Bourne shell all have echo built-in commands, which, by default, is invoked if the user calls echo
without a full pathname. See shell_builtins(1). sh's echo, ksh's echo, ksh93's echo, and /usr/bin/echo understand the back-slashed escape
characters, except that sh's echo does not understand a as the alert character. In addition, ksh's and ksh93's echo does not have an -n
option. sh's echo and /usr/bin/echo have an -n option if the SYSV3 environment variable is set (see ENVIRONMENT VARIABLES below). csh's
echo and /usr/ucb/echo, on the other hand, have an -n option, but do not understand the back-slashed escape characters. sh and ksh deter-
mine whether /usr/ucb/echo is found first in the PATH and, if so, they adapt the behavior of the echo builtin to match /usr/ucb/echo.
OPERANDS
The following operand is supported:
string A string to be written to standard output. If any operand is "-n", it is treated as a string, not an option. The following char-
acter sequences is recognized within any of the arguments:
a Alert character.
Backspace.
c Print line without new-line. All characters following the c in the argument are ignored.
f Form-feed.
New-line.
Carriage return.
Tab.
v Vertical tab.
\ Backslash.
n Where n is the 8-bit character whose ASCII code is the 1-, 2- or 3-digit octal number representing that character.
USAGE
Portable applications should not use -n (as the first argument) or escape sequences.
The printf(1) utility can be used portably to emulate any of the traditional behaviors of the echo utility as follows:
o The Solaris 2.6 operating environment or compatible version's /usr/bin/echo is equivalent to:
printf "%b
" "$*"
o The /usr/ucb/echo is equivalent to:
if [ "X$1" = "X-n" ]
then
shift
printf "%s" "$*"
else
printf "%s
" "$*"
fi
New applications are encouraged to use printf instead of echo.
EXAMPLES
Example 1 Finding how far below root your current directory is located
You can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o Echo your current-working-directory's full pathname.
o Pipe the output through tr to translate the path's embedded slash-characters into space-characters.
o Pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo $PWD | tr '/' ' ' | wc -w
See tr(1) and wc(1) for their functionality.
Below are the different flavors for echoing a string without a NEWLINE:
Example 2 /usr/bin/echo
example% /usr/bin/echo "$USER's current directory is $PWDc"
Example 3 sh/ksh shells
example$ echo "$USER's current directory is $PWDc"
Example 4 csh shell
example% echo -n "$USER's current directory is $PWD"
Example 5 /usr/ucb/echo
example% /usr/ucb/echo -n "$USER's current directory is $PWD"
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of echo: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
SYSV3 This environment variable is used to provide compatibility with INTERACTIVE UNIX System and SCO UNIX installation scripts. It is
intended for compatibility only and should not be used in new scripts. This variable is applicable only for Solaris x86 platforms,
not Solaris SPARC systems.
EXIT STATUS
The following error values are returned:
0 Successful completion.
>0 An error occurred.

When representing an 8-bit character by using the escape convention n, the n must always be preceded by the digit zero(0).
For example, typing: echo 'WARNING: 7' prints the phrase WARNING: and sounds the "bell" on your terminal. The use of single (or double)
quotes (or two backslashes) is required to protect the "" that precedes the "07".
Following the , up to three digits are used in constructing the octal output character. If, following the n, you want to echo addi-
tional digits that are not part of the octal representation, you must use the full 3-digit n. For example, if you want to echo "ESC 7" you
must use the three digits "033" rather than just the two digits "33" after the .
2 digits Incorrect: echo "
