So, I'm writing a shell script to help automate a process I'm doing. Basically I want to take input from the user for 2 variables, then create a file that consists of:
then run an awk script. I'm pretty new to unix though, and so far I've been creating new files by hitting ctrl-d at the end of my input, like so:
Code:
cat > script.awk
{
do stuff
}
(ctrl-d)
My google-fu is failing me. Is there a way I can tell the script "this is where the file you're making ends" without hitting ctrl-d? Really stupid question I know, but hopefully there's a simple answer!
I'm having trouble with Abnormal Termination errors. What are they, what causes them and how can I prevent them from happening? Are they application specific? (2 Replies)
Hello all,
Here is the problem:
A ksh script (let's call it abc.sh) gets kicked off from a menu program using "nohup abc.sh &". The process ID of abc.sh can be recieved (pid=$!).
abc.sh runs an Oracle PL/SQL script (it creates a child process).
In order to stop the abc.sh (and the child)... (5 Replies)
I'm writing a script to archive data. First, the files are all rsync'd to the archive directory via NFS mounts(I know not the most efficient, but the only choice in this situation), then I use md5sum to validate the transfers. During execution of the script, it will exit for no apparent reason. It... (6 Replies)

readkey
readkey(3alleg4) Allegro manual readkey(3alleg4)NAME
readkey - Returns the next character from the keyboard buffer. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int readkey();
DESCRIPTION
Returns the next character from the keyboard buffer, in ASCII format. If the buffer is empty, it waits until a key is pressed. You can see
if there are queued keypresses with keypressed().
The low byte of the return value contains the ASCII code of the key, and the high byte the scancode. The scancode remains the same whatever
the state of the shift, ctrl and alt keys, while the ASCII code is affected by shift and ctrl in the normal way (shift changes case,
ctrl+letter gives the position of that letter in the alphabet, eg. ctrl+A = 1, ctrl+B = 2, etc). Pressing alt+key returns only the scan-
code, with a zero ASCII code in the low byte. For example:
int val;
...
val = readkey();
if ((val & 0xff) == 'd') /* by ASCII code */
allegro_message("You pressed 'd'
");
if ((val >> 8) == KEY_SPACE) /* by scancode */
allegro_message("You pressed Space
");
if ((val & 0xff) == 3) /* ctrl+letter */
allegro_message("You pressed Control+C
");
if (val == (KEY_X << 8)) /* alt+letter */
allegro_message("You pressed Alt+X
");
This function cannot return character values greater than 255. If you need to read Unicode input, use ureadkey() instead.
