How Can I Solve Open Gl Problem

hi all,
I'm new here.
I have similar problem with running a C project that uses GLUT/OpenGL graphics...


every run result with the two lines:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

sometimes the graphics works ok sometimes there is an infinite loop, but every execution result with the two lines above.

what is the meaning of these 2 lines?
Is it an Error or Warning?
How can I fix the code?

My guess is that there is a fundamental problem with the graphics Glut Library...Or that I didn't write the MakeFile OK

Please help me, I would extremly appriciate it.

I want to And search grep shell

but It's hard to grep variable


---------------------------------------------------------------
#!/bin/bash


if [ $# -eq 0 ]
then
echo "Ussage: phone searchfor [...searchfor]"
echo "(You didn't tell me what you want to search for )"

else

pass=0
find=""

for idx in $*
do
if [ -n "$idx" ]
then
if [ $pass -eq 0 ]
then
find=$(egrep "$idx" mydata)
pass=1

else

find=$("$find" | grep "$idx")

echo $find
fi
fi

done

if [ -z "$find" ]
then
echo "There is no such thing"
else

echo $find | awk -f display.awk

fi

fi

-----------------------------------------------------

there is one error : command not found

in find=$("$find" | grep "$idx")

how can I grep variable and store it into variable?

I've been using this a lot:

find <directory to start search at> -name "<files to search in>" -type f | xargs grep "<string to search for>"

e.g.

find /usr/include -name "*.h" -type f | xargs grep "#define UINT"

now what if I wanted to output the results to a file?

I am writing a script to check whether a "sysinfo" is installed in a system or not. sysinfo is a tool that gives information about the system. Its is installed in /usr/local/bin. so at CLI when I type sysinfo, it will display output.

#!/bin/bash
sysinfo=`/usr/local/bin/sysinfo`
echo "$sysinfo"
if [ "$?" = 0 ];then
echo "sysinfo installed"
else
echo "Please install sysinfo"
fi

Concept is, I run the command if it is present, it will show output and exit status of command is 0 else it is not installed. But it is not working as expected. Any thoughts , idea, suggestion.

Hi All..

I need to give four lines of gap(Freespace) between two command outputs.

what i did was below

Code:

echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
print "***************** LEVEL 2: Truncating  Tables: Success:  tables Truncated ***********************" >> $LOG/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
echo "" >>$LOG_DIR/$LOG_NAME
# Run the load scripts.
echo "***************** LEVEL 3: Loading Dupe Check Tables: Success: Dupe Check tables Loaded***********************" >> $LOG/$LOG_NAME

Is there any better way of writing this command to leave multiple lines between two commands.

Please advise...

Hello, I'm trying to get bumblebee to work running Ubuntu 15.04.
I've followed this guide to get to the point I am now, but I'm getting an error that I couldn't even google the way out of it.

This is what I get from demencia@demencia-laptop:~$ primusrun glxinfo | grep OpenGL


primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Failed to load module "mouse" (module does not exist, 0)

But I was told that that error is not really important that I should have a look at my /var/log/Xorg.8.log, where I found my dead end.

Here's my /var/log/Xorg.8.log
file.

Any ideas?

I need to execute this .bashrc string:

alias lml='grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' mail.log | grep "relay=" | awk '{print $8}'' #list mail log

I have tried enclosing the string in alias as lml="..." and alias lml=`...` to no avail. The problem is apparently with the grep "relay=" in that it has to be enclosed in "", as well as the awk that has to be enclosed in ''.

Any ideas on how to get this setup? Thanks.

Hi Forum members,

I'm interested to get the date on which particular command was ran.

I've below in my .bashrc

Code:

export HISTTIMEFORMAT="%d/%m/%y %T "

I ran history | grep "cp" | less

I get an output like:

Quote:
1288 27/05/15 09:12:55 sacct -j 767151 --format=elapsed,ncpus,state
27/05 is today's date. But I'm interested for the date, the above output was ran.

What am I missing?

Hi,

I am running awk command on remote server it is not giving desired results but if i run the same command on local server. it works as expected. Can anybody help me to resolve this and let me know the logic behind this?

Remote server

# ssh test 'free -g | grep Mem | awk -F " " '{ print $2 }''
awk: cmd. line:1: {
awk: cmd. line:1: ^ unexpected newline or end of string

local server
# free -g | grep Mem | awk -F " " '{ print $2 }'
31


Thanks in advance.

Hi,
I made some little applications with qt creator and i wanted to run them on an embedded linux board (linux 2.6.24). To transfer the files i use a SD card. If i move the applications to "/bin" after having mounted the SD card and then "chmod a+x" them then i have no problem running them.
But if i mount the SD card and try to run the applications directly in the folder where i mount it i have an error : "Permission denied". Also when using the command "ls" i notice that if i keep the files in the mounting folder and try to "chmod a+x" them, the modification don't happen. They stay "greyed" and don't go "green". (I don't know if this color code is a standart for linux terminal but maybe this could help you understand the problem).
When mounting the SD card i use the command :
Code:

mount -t vfat /dev/mmcblk0p1 /mnt/SD

So the files are located in /mnt/SD.

Am i missing something or is it not possible to run something like that ?

EDIT :
I tried "mount -t vfat -o umask=0000 /dev/mmcblk0p1 /mnt/SD" to chnage how i am mounting the SD card.

Still "Permission Denied".

With "ls -l" i can see that the permissions are staying :
-rw-rw-rw-

Even if i try something like "chmod 777".

It seems to be a problem related to the fact that the sd card is formated as fat32 but it must stay like that.
