find open port on machine

You can use the NETSTAT command to quickly see all the used and listening ports on your computer. Note it is not a complete substitute for a port scanning tool. If you’d like to have your computer remotely scanned for open ports use our Security Scan instead.

To see a list of listening ports, open Command Prompt and type:

C:\> netstat -an |find /i “listening”

You can change “listening” to “established” to see what ports your computer actually communicates with.

It is also useful to use the -o switch with the NETSTAT command to also get a list of all the owning process ID associated with each connection. You can then use those process ids (PIDs) to find out the name of the processes associated with open/listening ports in the Windows Task Manager

C:\> netstat -ao |find /i “listening”

To see all open, closing, established and listening ports, simply use:

C:\> netstat -a (or netstat -ao in XP/Win2k3)

You can also make the netstat command refresh periodically by adding a number of seconds at the end, for example, to make it refresh every 5 seconds, use something like:

C:\> netstat -an 5

Create and apply Patch in git

Creating Patch in git is quite easy and useful when you want to transfer your changes from one branch to another or from one machine to another.

so here is the command you use:

once you clone repo from git using :

git clone git://github.com/xyx/xyx.git
cd xyx
git checkout -b branch_1

git checkout -b : it will create new branch with branch_1 name

creating patch

git log --pretty=oneline -3
git format-patch master --stdout > patch_name.patch

above command create new patch file with name patch_name.patch.

now applying patch:
use following command to easily apply patch to branch, apply command shows what are the changes patch will do in your current branch

git apply --check patch_name.patch

use following command to apply the patch

git am --signoff < patch_name.patch
