Programming :: Closing Parenthesis Script - Two Missing
Aug 30, 2010
I have a file with several parentheses, both () and []. All of them should be closed, but apparently, one of them is open. In order to run a program, I need all of them to be closed... For example, if I write: ((bla (bla (bla)) I would have two parentheses missing. That's what I mean. But I have several parentheses in the file... it would take me ages to do it manually. Is there a way to check which parenthesis is open? can it be done?

Is there any method for placing translations in parenthesis at first occurrence? I need something similar to the acronym package, but instead, storing translations and printing brackets only after the first occurrence.
E.g. (pseudo-code):
Results in:
Do you like to eat bananas (xiangjiao)? No I don't like to eat bananas.

In C++ language, we can do the following compound tests,
Code:
std::string a, b, c, d;
if ((a == "Yes" && b == "Yes" ) || (c == "Yes" && d == "Yes")) { ... }
In bash scripts, how can we do the parenthesis around compound tests?
Code:
if [ "$a" = "Yes" ] && [ "$b = "Yes" ] [ "$c" = "Yes" ] && [ "$d" = "Yes" ]; then
...

As we know, every process has a table with a file descriptor table, in which each entry contains a file pointer pointing to the corresponding file table which contains a v-node pointer pointing to the v-node table.
When closing a file descriptor, are all these data structure deleted?

I have written a server application which has select for both incoming new client connection requests and incoming data from client. I am able to process incoming connection requests and client data.
For example, server has 8 clients connected to it. If client 3 disconnects from server, how will server come to know this client has disconnected and to close its client socket fd gracefully? Does server's select get data on that client socket fd as 'close' data or any error code in recv() function that notifies server to close this client socket fd? Also if client disconnects abruptly without sending close request to server, how should server handle this? Does server get "EPIPE" error?

I have a pthread waiting forever on a POSIX message queue and then call mq_close and mq_unlink on the POSIX message queue. I've found that the pthread never wakes up from it's call to mq_receive and remains blocked indefinitely. Is there a way to wakeup all pthreads blocked on a POSIX message queue after calling mq_close/mq_unlink? The goal is to include error handling during message queue deletion to avoid leaving any pthreads blocked forever.

i was wondering if there is away to avoid application from closing if a specific library not found? for example: if my application uses libPng and it wasn't found on the system running my app (binary and not source), is there anyway to just disable the part that uses png from my application?

When I see a typical reference to a Unix manual, it often follows by a number surrounded by parentheses. For instance syslog.conf (5). I am sure this means something, but Googling it is impossible.

I am using an imx27 and have a timer set up for 100 ms and a loop to count the pulses while the timer has not expired. I get about 90 % reliable results but every once in a while i get one that is out to lunch. I am reading in a signal that is about 500khz and counting on an transition. I usually get around 85k count. But i will randomly get a 50k count.

I have been using Ubuntu 10.04 LTS for several months and recently the system has stopped closing down cleanly. It starts okay and runs just fine, but when I come to closing down it doesn't do anything after I've clicked on the shut down button. The same happens with the restart button. I have been closing the system by pressing the power button on the front of my tower. I have no idea as to why it won't close ... I haven't installed any extra software, so I guess it's a system problem. Closing down by pressing the power button cannot be doing the OS any good, so I could do with a fix ASAP on this one.

Since my laptop went back to DELL to be repaired closing the lid does nothing. It used to put the laptop into suspend. I even tried on my windows partition and closing it still does nothing. I suspected that the switch(?) that controls this is not sending any data to the laptop - is there away to see if any input is being received when the lid is closed? Or does anyone have any other thoughts on what might be at fault?

Is there a way to stop conky from closing when I click on it? I have a few set up as a system monitor bar on the desktop, and I'd like to anchor them there from accidental clicking so I don't have to restart my script.

I have some screen questions. First, can you give screens names (such as whatever app you're screening), and second, how do you exit from a screen without closing the app (ie exit screen back to the command prompt, do your thing, then screen -r it)?

This is probably a stupid question, but I haven't been able to figure it out on my own.
If I run Amarok and then click on Amarok -> Quit, the main Amarok window disappears but a tray icon remains:
How do I open Amarok again?
Choosing Amarok from the main menu does nothing. Running amarok in the terminal produces:
multi@aux:~$ amarok
Amarok is already running!
