computerdeal 8 | sed -r 's/[0123456789JQKAHSDC]+/ * /g'
and
Code:
echo " The Card in Play is: "$(deal) | tee /home/cogiz/cardinplay.txt
In both cases the deal and computerdeal function are executed in a subshell, in the first case as the left hand side of a pipe, in the second case as part of a command substitution. The global variables that are set inside those functions are local to that subshell. When the subshell finishes, those variables and their values will be lost...
By contrast the first time the deal function is called:
Code:
deal 8
it is done in the current shell itself and the value of global variable cards_remaining that gets set inside that function is the value that gets printed at the end..
So instead you could run those functions in the current shell and then use the global variables that are being set inside them...

How can I get a bash script to wait and read and count $i messages that a running program (drbl clonezilla) sends to the console (terminal) and only then move on to the next line in the script when the count is matched (the next line is the last line of the script and is a reboot)?

So, I made a script beginning with #!/bin/bash on gedit.
And I double clicked it to run in terminal and I end up with "The child process exited normally with status 127" and "command not found".
If I run the same script from the terminal as "tcsh (script name)" it runs just fine.

variable
variable(n) Tcl Built-In Commands variable(n)
__________________________________________________________________________________________________________________________________________________NAME
variable - create and initialize a namespace variable
SYNOPSIS
variable ?name value...? name ?value?
_________________________________________________________________DESCRIPTION
This command is normally used within a namespace eval command to create one or more variables within a namespace. Each variable name is
initialized with value. The value for the last variable is optional.
If a variable name does not exist, it is created. In this case, if value is specified, it is assigned to the newly created variable. If
no value is specified, the new variable is left undefined. If the variable already exists, it is set to value if value is specified or
left unchanged if no value is given. Normally, name is unqualified (does not include the names of any containing namespaces), and the
variable is created in the current namespace. If name includes any namespace qualifiers, the variable is created in the specified names-
pace. If the variable is not defined, it will be visible to the namespace which command, but not to the info exists command.
If the variable command is executed inside a Tcl procedure, it creates local variables linked to the corresponding namespace variables (and
therefore these variables are listed by info locals.) In this way the variable command resembles the global command, although the global
command only links to variables in the global namespace. If any values are given, they are used to modify the values of the associated
namespace variables. If a namespace variable does not exist, it is created and optionally initialized.
A name argument cannot reference an element within an array. Instead, name should reference the entire array, and the initialization value
should be left off. After the variable has been declared, elements within the array can be set using ordinary set or array commands.
