I have no idea what the relevence of DGPickett's post is.
The ctrl/z is being picked up by shell before it gets to your program. In foreground ctrl/z is commonly mapped to SUSP (suspend). The program can be brought to foreground with the "fg" Shell command.
To see the mapping of the various control keys in your session:
Each and every one of these can (and often will) be disabled or changed to suit individual terminals or applications. See "man stty" for your O/S.
Many people re-map INTR to ctrl/c for consistency with MSDOS but on many terminals it is not mapped to anything by default.
Hi,

"Execution: 85328 Signal d'alarme".
If I edit this file with "vi", I ve got the same error after a while (about 1 minute).
If I try with another user I still have the problem.
But if I rename this file, no problem.

Hi everyone,
Is there a variable or built in function in the Unix env. for me to obtain the name of a signal that is caught? As far as I understand only a numeric value of the signal is returned to the handler.
For example:
void handler (int signum)

Hello e'bdy,
We have WebSphere MQ running on AIX 5.1
Every weekend MQ receives a kill -30 signal from some process or user and offloads a big error file. There is no way in MQ through which that process can be tracked.
Is there something which i can do on UNIX level to trap the process?

Hello,
I'm doing a project of OS simulation (Process Scheduling, to be very specific). Can anyone, please, explain what exactly happens in the background when we see "Sending all processes the KILL signal...........". How is it sent to each process? Is it that something like a boolean is stored... (3 Replies)

__________________________________________________________________________________________________________________________________________________NAME
term::ansi::ctrl::unix - Control operations and queries
SYNOPSIS
package require Tcl 8.4
package require term::ansi::ctrl::unix ?0.1?
::term::ansi::ctrl::unix::import ?ns? ?arg...?
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::columns
::term::ansi::ctrl::unix::rows
_________________________________________________________________DESCRIPTION
WARNING: This package is unix-specific and depends on the availability of two unix system commands for terminal control, i.e. stty and
tput, both of which have to be found in the $PATH. If any of these two commands is missing the loading of the package will fail.
The package provides commands to switch the standard input of the current process between raw and cooked input modes, and to query the size
of terminals, i.e. the available number of columns and lines.
API
INTROSPECTION
::term::ansi::ctrl::unix::import ?ns? ?arg...?
This command imports some or all attribute commands into the namespace ns. This is by default the namespace ctrl. Note that this is
relative namespace name, placing the imported command into a child of the current namespace. By default all commands are imported,
this can howver be restricted by listing the names of the wanted commands after the namespace argument.
OPERATIONS
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to raw input mode. This means that from then on all characters typed
by the user are immediately reported to the application instead of waiting in the OS buffer until the Enter/Return key is received.
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to cooked input mode. This means that from then on all characters
typed by the user are kept in OS buffers for editing until the Enter/Return key is received.
::term::ansi::ctrl::unix::columns
This command queries the terminal connected to the standard input for the number of columns available for display.
::term::ansi::ctrl::unix::rows
This command queries the terminal connected to the standard input for the number of rows (aka lines) available for display.
