I'm a new user to unix and I want to be able to pick and choose different xterm colors via 3rd botton menu. I'm currently pico'd into my .fvwm2rc file and this is what I have under my bottons:
Please advise

my shell is /sbin/sh. i added stty susp '^Z' with the intention of being able to switch between foreground and background. but the result was strange.
i had 2 servers. one is sun the os is 8 and the other is hpux v11. both of them had the same shell. but on hpux, it works perfectly fine while... (9 Replies)
When I telnet (ssh) over to my Fedora system, I find the colors horrible. For instance, regular files are white text, which is fine, but directories show up as dark blue which is virtually invisible against the black background). Additionally, when using vi, I find the colors great doing perl... (3 Replies)
I am using a telnet session (VT100) and need to modify my .profile so that it will set the color of the telnet session. I am not using Xterm (ie: can't use .Xdefaults). I am able to change the colors via menu's but need to preset in .profile. Is this possible??? Can't find anything at all on how... (3 Replies)
hi, i am just wondering that wen we give the following code we make a process run in background...can the viceversa be performed?i.e can this be made foreground again

I don't know exactly when or why, maybe running less or some command, my white text on a black background gets inverted and all the text looks like it is "selected", it is white background with black text.

What are all the difference between a Background and Foreground processes ?!
A Background process does not have access to STDIN and OUT.. What else ?
Is there any detailed description available somewhere ? (5 Replies)
Hi, guys:
I am working on my own shell using c. When I put a process into the background, how can I put it back to the foreground using tcsetpgrp?
Thanks (3 Replies)
Hi,
Need an urgent help. I have a program executing in foreground. I need to execute it in background and also to remove terminal dependency.
Thanks In advance.

random
RANDOM(3) Library Functions Manual RANDOM(3)NAME
random, srandom, initstate, setstate - better random number generator; routines for changing generators
SYNOPSIS
#include <stdlib.h>
long random(void)
void srandom(unsigned seed)
char *initstate(unsigned seed, char *state, int n)
char *setstate(char *state)
DESCRIPTION
Random 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 (2**31)-1. The period of this random number generator is very large, approximately
16*((2**31)-1).
Random/srandom have (almost) the same calling sequence and initialization properties as rand/srand. The difference is that rand(3) pro-
duces a much less random sequence -- in fact, the low dozen bits generated by rand go through a cyclic pattern. All the bits generated by
random are usable. For example, ``random()&01'' will produce a random binary value.
Unlike srand, srandom does not return the old seed; the reason for this is that the amount of state information used is much more than a
single word. (Two other routines are provided to deal with restarting/changing random number generators). Like rand(3), however, random
will by default produce a sequence of numbers that can be duplicated by calling srandom with 1 as the seed.
The initstate routine allows a state array, passed in as an argument, to be initialized for future use. The size of the state array (in
bytes) is used by initstate to decide how sophisticated a random number generator it should use -- the more state, the better the random
numbers will be. (Current "optimal" values for the amount of state information 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). The seed for the initialization (which specifies
a starting point for the random number sequence, and provides for restarting at the same point) is also an argument. Initstate returns a
pointer to the previous state information array.
Once a state has been initialized, the setstate routine provides for rapid switching between states. Setstate returns a pointer to the
previous state array; its argument state array is used for further random number generation until the next call to initstate or setstate.
Once a state array has been initialized, it may be restarted at a different point either by calling initstate (with the desired seed, the
state array, and its size) or by calling both setstate (with the state array) and srandom (with the desired seed). The advantage of call-
ing both setstate and srandom is that the size of the state array does not have to be remembered after it is initialized.
With 256 bytes of state information, the period of the random number generator is greater than 2**69 which should be sufficient for most
purposes.

DIAGNOSTICS
If initstate is called with less than 8 bytes of state information, or if setstate detects that the state information has been garbled,
error messages are printed on the standard error output.
SEE ALSO rand(3).
NOTES
initstate and setstate are not declared in <stdlib.h>, programmers must provide their own declarations.
BUGS
About 2/3 the speed of rand(3).
