for one of my script i need to print text between 2 pattern when a match if found inside, i dont find how to make it simple.
the content of the file is:

if i seach enclosure-7 for exemple i would like it return :

It's a mix between a grep and a sed -n "/===== /,/^$/p" but can't find it...
Thanks in advance for your answers :)
This is the answer:
perl -0777 -lne 'print for grep /enclosure-7/, /^=====.*?^$.*?\n/mgs' file.txt
p will be treated as a regular expression
awk -v p='enclosure-7' -v RS= '$0~p' file.dat
Empty RS means that records are separated by one or more blank lines and nothing else.
With sed:
sed '/^=====/{:a;N;/\n$/!ba;/enclosure-7/!d}' file

I'm trying to setup a Concourse CI environment with a Windows 7 worker.
I have one machine under Ubuntu Server (16.04) hosting my TSA server and one worker (for the support of git resources), and a second one under Windows 7 hosting a worker.
Everything seems to work fine as:
I can login into the web ui
the fly -t my_concourseci workers command returns :
name containers platform tags team state version
ubuntu 1 linux none none running 1.1
windows7 0 windows none none running 1.1
the fly -t my_concourseci execute -c test.yml command returns:
executing build 146
initializing
running echo Hello World!
Hello World!
with the following content in test.yml file:
platform: windows
run:
path: echo
args: [ "Hello World!" ]
Nevertheless when I add an input to my task:
platform: windows
> inputs:
> - name: concourse
run:
path: echo
args: [ "Hello World!" ]
I get the following error:
executing build 148

If I look at the windows worker log I got this error that comes up:
{"timestamp":"1500642862.643555164",
"source":"baggageclaim",
"message":"baggageclaim.api.volume-server.stream-in.bad-stream-payload",

"session":"2.1.8730",
"volume":"15bf1fc6-0727-4962-6c84-18446e54ab96"}
}
Any ideas about what can cause a not in gzip format error ? Knowing that if I run the exact same task on a linux platform every works fine.

running echo Hello World!
succeeded
Thanks.
Launch powershell as Administrator, and run the concourse_worker.exe from there. That worked for me.
I am running a Windows Server 2016 Base on AWS based on this AMI ami-e1876a98
Thanks for your answers, it helps me solve my problem.
I were starting my concourse worker within a MSYS 1.0 environment. The thing is that MSYS contains tar and gunzip binaries within the $PATH. When I started concourse worker inside a Power Shell or cmd.exe without any MSYS unix-like binaries in the $PATH it worked like a charm !
Note: Be sure to have no MSYS binaries in the $PATH Windows environment variable for this to work, especially check that Git-Bash environment tools are not added to your windows $PATH environment variable.
Thanks again.
I'm trying to change the value of GPIO port manually.
To change the value of gpio18 (physical port 12), I did as follow:
# gpio unexportall
# echo 18 > /sys/class/gpio/export
# echo out > /sys/class/gpio/gpio18/direction
# cat /sys/class/gpio/gpio18/value #output is 0
# echo 1 > /sys/class/gpio/gpio18/value
# cat /sys/class/gpio/gpio18/value #output is 1
For gpio7 (physical port 26) I perform the exact commands as above. But the value remains 0:
# echo 7 > /sys/class/gpio/export
# echo out > /sys/class/gpio/gpio7/direction
# cat /sys/class/gpio/gpio7/value #output is 0
# echo 1 > /sys/class/gpio/gpio7/value
# cat /sys/class/gpio/gpio7/value #output is 0 again
I've tried with all other gpio ports. All ports function properly except gpio7 and gpio11 (the value is always 0).
By the way before using this raspberry pi, I was working with another raspberry pi2. Strangely the gpio7 in the previous raspberry pi had the same problem too. Is it a hardware problem or I am doing something wrong?
EDIt: I have also used Wiringpi and J4Pi, the result is the same.
Drag and Drop isnt work, resizing too. Only copy-paste is work sometimes.
I thought that it is becouse vmblock errors, but after "emerge vmware-modules" vmblock errors gone and problem still exists.

I am not a linux expert, but if I understand it right, there is just 15Mb free memory, but no task uses more than 0.6%. Than why is not there more free?
Memory is not exclusively allocated by Processes.
The bootloader and the init ram filesystem is stored in memory.
The kernel (could be very big) is loaded into memory.
The kernel reserve memory for it's processes. ps shows 0.0% for these system processes.
Driver allocate buffer memory
The graphics card needs memory
If you have not configured your swap space on a harddrive or SD card, it uses memory.
The network system allocates memory for unix sockets and shared memory.
100 processes with 0.1 % are 10%.
And, if you start a process and stop it not all of it memory will be released.
Try it. Show the memory usage with free. Start a process that need some memory. Stop the process and use free again. I would bet that there is more memory usage than before.
Edit
Here is an example of a pi with less memory usage. I have no problems running java on it. I have a WLAN Dongle and a original NOIR CAM installed.
I installed Raspbian Wheezy. I used a kernel that I compiled from sources:
> uname -a
