Liunx Common Commands
================================================================================

1. Remotely copy files
---------------------------------------------------------------------------------
scp-r [email protected]:/home2/xyf/a20/android4.0./android/

2. Telnet
---------------------------------------------------------------------------------
SSH [email protected]

Convert L:/fs:ntfs//L is your disk character formatted USB drive, when your disk is larger than 4G, want to copy larger than 4G file

3. Log in to the drive configuration file
---------------------------------------------------------------------------------
Make Menuconfig Arch=arm

Select platform for ARM the default is x86.

4. Printing information
---------------------------------------------------------------------------------
ADB shell Logcat-b Radio > Logcat-radio.log-3g dongle

At the end of preinstall.sh, add the following command:

echo 8 >/PROC/SYS/KERNEL/PRINTK

Echo 1 >/sys/class/axppower/axpdebug
cat/proc/kmsg >/data/local/kmsg ' Date +%y%m%d_%h%m%s ' &

Logcat >/data/local/logcat ' Date +%y%m%d_%h%m%s ' &

ADB shell
ls | BusyBox grep DRM

The above command generates log information under/data/local/logcat and is named after the boot time.

5. After we have modified the tool SYS_CONFIG1, if we can not upgrade the entire firmware let it take effect
---------------------------------------------------------------------------------

After modifying the SYS_CONFIG1, if you can not upgrade the entire firmware let it take effect

1>. In Android Shell, Mount/dev/block/nanda to a node:
Mount-t Vfat/dev/block/nanda/mnt/nand

2>. Modify the build firmware after SYS_CONFIG1, and then locate Scrpt.bin and Script0.bin under Lichee\tools\pack\out\bootfs

3>. Then, after connecting with ADB, push Scritp.bin and Script0.bin to the root of the Mount node and replace the original file with the same name:
ADB push script*.bin/mnt/nand/

4>. Last sync restart

ADB shell
Sync
Reboot

6. How to replace the kernel separately
---------------------------------------------------------------------------------
1>. The Android Shell will mount/dev/block/nanda to a node:
Mount-t Vfat/dev/block/nanda/mnt/nand

2>. After connecting with ADB, push the bimage directly to the Linux directory of the Mount node and replace the Bimage:
ADB push Bimage/mnt/nand/linux

3>. Sync reboot

ADB shell
Sync
Reboot

7.git and Repo basic commands

Repo forall-p-c ' git log--oneline--name-only--committer=cqq '//view files that have been modified
Repo forall-c git config core.filemode false//ignore permission modifications

Update, it is recommended that a backup branch be built before the update.
This way, even if there is a problem with the new code, you can switch the old Code sub-expenditure software, the new code is stable after the backup branch can be deleted
Repo Checkout Develop
Repo Forall-p-C git pull exdroid develop//android

Git saves the progress of the work

Git stash Save
git checkout xxx

git checkout Xxx_
Git stash pop recovery

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

Problem point:

If no other git process are currently running, this probably means a
Git process crashed in this repository earlier. Make sure no other git
Process is running and remove the file manually to continue.

Method:
Rm-f./.git/index.lock

8. Find Command View
---------------------------------------------------------------------------------

1. Find./-name "string"

Find. -type F | Xargs sed-i ' s/a31st/xxx/g '

2. grep "string"./-rn

3. Cat/system/usr/device.info

4. Cat/data/device.info

9. Logcat
---------------------------------------------------------------------------------
Basic commands

1. ADB logcat-c clears all previous logs

2.ADB logcat-d This command is in the reverse of time. The log that you first operated and then knocked on the command was the log that you just manipulated and automatically exited log mode.

3.adb logcat-s "XXX" This is set to filter for example you just want to view Firstdemo's log to replace the last XXX

Filter

1.ADB Logcat activitymanager:i Myapp:d *:s

Eg:activitymanage:
I/activitymanager (585): Starting activity:intent {action=android.intent.action ...}

The last element of the expression above *:s, is to set all the labels as "silent", all the logs are only shown with "View" and "MyApp", another use of *:s is to be able to ensure that the log output is in accordance with the filter description limit, Also let the filter output to the log as an item.

2.ADB Logcat *:w
The above filter statement refers to the display of log information with priority warning or higher

3. ADB logcat-v thread-to [ADB] logcat [-v]

Here is the log format generated with thread:
Note that you only have the-V option to specify the output format options.

4. View the available log buffers

The Android log system has a loop buffer, and not all log systems have a default loop buffer. In order to get the log information, you need to start logcat with the-B option. If you want to use a loop buffer, you need to see the remaining loop buffer period:

radio-View the information about the buffer.

events-view the buffer associated with the event.

main-viewing the primary log buffer

[ADB] logcat [-b]

The following example shows how to view the log buffer containing radio and telephony information:

ADB logcat-b Radio

5. Logcat-v time-s "xxx"

10. Kernel Print Level
---------------------------------------------------------------------------------

echo 8 > PROC/SYS/KERNEL/PRINTK to see all kernel prints
Echo 1 >/sys/class/axppower/axpdebug

Logcat-v Time >/sdcard/log1 $
Cat/proc/kmsg >/SDCARD/KMSG1 & directed to SD card

20.ssh
---------------------------------
Use Ssh-keygen to set up SSH without password login

Git is a distributed Code management tool, remote code management is SSH-based, so to use the remote git requires SSH configuration.

The SSH configuration for GitHub is as follows:
One

Set the user name and email for git:
$ git config--global user.name "Xuhaiyan"
$ git config--global user.email "[Email protected]"

Second, the process of generating SSH key:
1. See if you already have an SSH key: CD ~/.ssh
If there is no key then there will be no such folder, there is a backup to delete
2. Survival key:
$ ssh-keygen-t rsa-c "[Email protected]"
Press 3 to enter, the password is empty.
Your identification has been saved In/home/tekkub/.ssh/id_rsa.
Your public key has been saved in/home/tekkub/.ssh/id_rsa.pub.
The key fingerprint is:
..................

Finally, two files were obtained: Id_rsa and Id_rsa.pub

3. Add the encryption key to the Ssh:ssh-add file name
Enter the password before you need it.
4. Add the SSH key on GitHub, which adds the public key in "Id_rsa.pub".

Open https://github.com/, log in to xuhaiyan825, and then add SSH.

5. Test: SSH [email protected]

The authenticity of host ' github.com (207.97.227.239) ' can ' t be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Is you sure want to continue connecting (yes/no)? Yes
Warning:permanently added ' github.com,207.97.227.239′ (RSA) to the list of known hosts.
Error:hi tekkub! You ' ve successfully authenticated, and GitHub does not provide shell access
Connection to github.com closed.

Third, start using GitHub
1. Get the source code:

$ git clone [email protected]:billyanyteen/github-services.git

2. So there's a repo on your machine.
3.git different from SVN is that git is distributed and there is no server concept. All the people have a repo on the machine, each submission is to their own machine repo
Warehouse initialization:

Git init

Generate a snapshot and deposit the project index:

git add

Files, git rm,git mv, etc...
Project Index submission:

Git commit

4. Collaborative programming:
Merge the local repo with repo from the remote origin,
Push local update to remote:

Git push Origin Master

Update remote updates to Local:

Git pull Origin Master

Add:
To add a remote repo:

$ git remote add upstream git://github.com/pjhyett/github-services.git

To rename a remote repo:

$ git://github.com/pjhyett/github-services.git to "upstream"

21.VI encryption
--------------------------------

Using the name X to save the file is encrypted.
eg
: X
Please enter your password

Decryption method:
: Set key=//setting key is not empty
: W
: X
Decryption complete

Forget the password, this has not been solved.

Tar unpacking compression command set --------------------------------

23.apktools
--------------------------------
dochiphdpreapk ~/a31box_g2000/android/device/softwinner/xx/preapk

24.touch--------------------------------
Update all C and C + +
Find $path-name ' *. [hhcc]* ' | Xargs touch-c

The issue of ADB occupancy
--------------------------------
One, command: ADB Nodaemon server to see which port is occupied

Second, command: Netstat-ano | Findstr "5037" lists the processes on which the ports are occupied

Third, in the task Manager to find the corresponding port-occupied process, and then kill the process.

or kill the process with a command: Ntsd-c q-p ""
