I'm writing a script to sync P4 code with an existing label using command "p4 sync #labelname".
I have a network folder mapped as (S:) where i have the workspace "check".
The issue i'm facing is when i issue the sync command, it is creating a duplicate directory as "SUVHTV~2"
in S: and updating the changes instead of updating in S:/check
Note: Workspace "check" is created using Perforce and Root is provided as (S:/check)
This seems like your environment variable for P4CLIENT is not set properly. Please explicitly set this variable in your script.
I am assuming you have cygwin/mks toolkit or some other unix-shell-on-windows software.
Try adding this line before you make the call to p4 sync command and see if it helps.
export P4CLIENT='check'

I have a ros (kinetic) environment set up on a raspberry pi 3 and am trying to get ros to execute upon startup via a simple bash script which calls roslaunch. Ros works in the user domain but fails when called from root.
Here is my launch_ros.sh script:
#!/bin/bash
source /home/pi/ros_catkin_ws/devel/setup.bash
export PYTHONPATH=/opt/ros/kinetic/lib/python2.7/dist-packages
roslaunch my_pkg pkg_launch.launch
When I run sudo /home/pi/Desktop/ros_launch.sh the roscore crashes with
ERROR: cannot launch node of type [rosout/rosout]: can't locate node
[rosout] in package [rosout] failed to start core service [/rosout]
The traceback for the exception was written to the log file
But, if I comment out
source /home/pi/ros_catkin_ws/devel/setup.bash
and execute /home/pi/Desktop/ros_launch.sh, ros works fine.
Also worthy of noting is if I leave the above source line uncommented when running in the user domain I get the same error as I do in the root. I think this might be pointing me to the solution but I am still very new to ros.
Has anyone come across this issue and found a solution?
In order to run a node as root after changing your shell to root using commands like sudo -i, You can source your current bash profile thats located inside your normal user .bashrc and use it inside root shell.
Try the following code:
#!/bin/bash
source /opt/ros/kinetic/setup.bash
source /home/pi/ros_catkin_ws/devel/setup.bash
export PYTHONPATH=/opt/ros/kinetic/lib/python2.7/dist-packages
roslaunch my_pkg pkg_launch.launch
You need to source your workspace devel to be able to find your own package.
But, you need to source ROS devel to be able to use roscd, roslaunch, ...
In the code below I added:
source /opt/ros/kinetic/setup.bash
to source ROS and be able to use it.
PS: If it's still not working you should try a short delay before running roslaunch.
I was accidentally in a conda environment (base only) and it was messing up big-time. Try disabling any Python virtual environments.
It really worked and it inspired me to report that I didn't have rosnode as a program when I was planning to call ROS scripts in my own applications. Calling source .bashrc directly from the Raspberry Pi's system would refresh the terminal, but there was no way for my program to take over. The solution was to place the required ROS environment scripts in a separate script like name init_env.sh and then call source init_env.sh before any other ROS scripts were executed.
i'm beginer in nativescript,i have correctly install ANDROID_HOME environment variable which return my sdk path after echo $ANDROID_HOME but despite this it return me The ANDROID_HOME environment variable is not set or it points to a non-existent directory. You will not be able to perform any build-related operations for Android
but if i put my project in the same directory with sdk directory it return me
Cannot resolve the specified connected device by the provided index or identifier. To list currently connected devices and verify that the specified index or identifier exists, run 'tns device'
I also notice that after each computer restarting environment variable disappear and i must resume a same process , i have edit .profile file, .bashrc file and zshrc file for environnement variable i have a same result
please tell me what wrong ... thank in advance
my ~./bashrc file
export ANDROID_HOME=/home/user/Android/Sdk
export PATH=$PATH:/home/user/Android/Sdk/tools
export PATH=$PATH:/home/user/Android/Sdk/platform-tools
export LD_LIBRARY_PATH=/home/user/Android/Sdk/emulator/lib64
In /home/user/Android/Sdk should be tools and platform-tools folders.
That's enough for me. (Linux Mint 18)
Maybe this information will be useful to someone:
Linux environment variables configuration files
.bashrc
This file is a variable for a particular user. It is loaded every time the user creates a terminal session, that is, in other words, opens a new terminal. All the environment variables created in this file take effect every time a new terminal session begins.
.bash_profile
These variables take effect every time the user connects remotely over SSH. If this file is missing the system will look for .bash_login or .profile.
/etc/environment
This file is for creating, editing and deleting any environment variables at the system level. The environment variables created in this file are available for the entire system, for each user and even for a remote connection.
/etc/bash.bashrc
System bashrc. This file is executed for each user, each time he creates a new terminal session. This only works for local users, when connected through the Internet, such variables will not be visible.
/etc/profile
System file profile. All variables from this file are accessible to any user on the system only if he entered remotely. But they will not be available when creating a local terminal session, that is, if you just open the terminal.
All the Linux environment variables created with these files can be deleted only by removing them from there. Only after each change, you need to either log out and log in, or execute this command:
$ source file_name
So, the environment variable can be of three types:
Local environment variables
These variables are defined only for the current session. They will be irretrievably erased after the session is completed, whether it is remote access or terminal emulator. They are not stored in any files, but are created and deleted using special commands.
Custom shell variables
These shell variables in Linux are defined for a specific user and are loaded each time it logs in using the local terminal, or it is remotely connected. Such variables are usually stored in configuration files: .bashrc, .bash_profile, .bash_login, .profile or in other files located in the user's directory.
System environment variables
These variables are available throughout the system, for all users. They are loaded when the system starts from the system configuration files: / etc / environment, / etc / profile, /etc/profile.d/ /etc/bash.bashrc.
If you are using nvm to manage different nodejs version, then try disabling nvm and using only one global nodejs version.
Regarding the environment variables that are being volatile, make sure that you track down the proper profile file that is being parse and place your changes there.
It would help if you can be more specific about your current platform. Then, people will be able to respond with more precision.
hi i solve my problem by adding in profile file environnement variable
export ANDROID_HOME=~/Android/Sdk
export ANDROID_HOME=~/Android/Sdk/tools
export ANDROID_HOME=~/Android/Sdk/platforms-tools
then i erased all path generate by all commands line entries from my terminal in .bashrc file(i think that it was that the problem source) . finally it work well thanks a lot to everybody for your helps
I want to make build automation tool using perforce as version control system.
When I run some batch to automatically download the latest version from the repository I want to check if a current working directory is valid.
For example, when I run
p4 add file.txt
for a file not under workspace, I get this message with error code = 1
Path 'c:\file.txt' is not under client's root 'D:\workspace'.
Is there some way to explicitly check if a directory is under client's root?
Do:
p4 where ...
to see where (if anywhere) your current directory is mapped in the current client view.
Note that when you're syncing (downloading) files from the depot the current working directory isn't necessarily important. Just run p4 sync to sync your entire workspace, or use p4 sync //depot/path/... to sync an absolute depot path if that's easier than getting your script to find the correct path relative to the current client machine.
I have created jekyll site. Regarding the deployment I don't want to host on github pages. To host private domain I came know from documentation to copy the all files from _site folder. That's all wicked.
Question:
Each time I add new blog post, I am running cmd>jekyll build then I am copying newly created html to hosted domain. Is there any easy way to update without compiling each time ?
The reason, Why I am asking is because it will updated by non technical person
Thanks for the help!!
If you don't want to use GitHub Pages, AFAIK there's no other way than to compile your site each time you make a change.
But of course you can script/automate as much as possible.
That's what I do with my own blog as well. I'm hosting it on my own webspace instead of GitHub Pages, so I need to do these steps for each update:
Compile on local machine
Upload via FTP
I can do this with a single click (okay, a single double-click).
Note: I'm on Windows, so the following solution is for Windows.
But if you're using Linux/MacOS/whatever, of course you can use the tools given there to build something similar.
I'm using a batch file (the Windows equivalent to a shell script) to compile my site and then call WinSCP, a free command-line FTP client.
WinSCP allows me to store session configurations, so I saved the connection to my server there once.
Because of this, I didn't want to commit WinSCP to my (public) repository, so my script expects WinSCP in the parent folder.
The batch file looks like this:
call jekyll build
echo If the build succeeded, press RETURN to upload!
pause
set uploadpath=%~dp0\_site
%~dp0\..\winscp.com /script=build-upload.txt /xmllog=build-upload.log
pause
The first parameter in the WinSCP call (/script=build-upload.txt) specifies the script file which contains the actual WinSCP commands
This is in the script file:
option batch abort
option confirm off
open blog
synchronize remote -delete "%uploadpath%"
close
exit
Some explanations:
%~dp0 (in the batch file) is the folder where the current batch file is
The set uploadpath=... line (in the batch file) saves the complete path to the generated site into an environment variable
The open blog line (in the script file) opens a connection to the pre-saved session configuration (which I named blog)
The synchronize remote ... line (in the script file) uses the synchronize command to sync from the local folder (saved in %uploadpath%, the environment variable from step 2) to the server.
IMO this solution is suitable for non-technical persons as well.
If the technical person in your case doesn't know how to use source control, you could even script committing & pushing, too.
There are a number of options available which are mentioned in the documentation: http://jekyllrb.com/docs/deployment-methods/
If you are using Git, I would recommend the Git Post-Receive Hook approach. It simply builds the site after the new code is received:
GIT_REPO=$HOME/myrepo.git
TMP_GIT_CLONE=$HOME/tmp/myrepo
PUBLIC_WWW=/var/www/myrepo
git clone $GIT_REPO $TMP_GIT_CLONE
jekyll build -s $TMP_GIT_CLONE -d $PUBLIC_WWW
rm -Rf $TMP_GIT_CLONE
exit
Since you mentioned that it will be updated by a non-technical person, you might try something like rack-jekyll to automatically rebuild when new files are FTP'd.
I'm using Jenkins to do continuous integration builds. I have quite a few jobs that have much of the same configuration code. I'm in the midst of pulling this all out into a common script file that I'd like to run pre and post build.
I've been unable to figure out how to set some environment variables within that script, so that both the Xcode build command, and the Jenkins build can see them.
Does anyone know if this is possible?
It is not possible to do exactly what you ask. A process cannot change the environment variables of another process. The pre and post and actual build steps run in different processes.
But you can create a script that sets the common environment variables and share that script between all your builds.
The would first call your shell to execute the commands in the script and then call xcodebuild:
# Note the dot in the beginning of the next line. It is not a typo.
. set_environment.sh
xcodebuild myawesomeapp.xcodeproj
The script could look like this:
export VARIABLE1=value1
export VARIABLE2=value2
How exactly your jobs will share the script depends on your environment and use case. You can
place the script in some well-known location on the Jenkins host or
place the script in the version controlled source tree if all your jobs share the same repository or
place the script in a repository of its own and make a Jenkins build which archives the script as a build artifact. All the other jobs would then use Copy Artifact plugin to get a copy of the script from the artifacts of script job.
From Apple's Technical Q&A QA1067 it appears that if you create the file /Users/YOU/.MacOSX/environment.plist and populate it with your desired environment variables that all processes (launched by the user with the environment.plist file in their home dir) will pick up these environment variables. You may need to restart your computer (or just log out and back in) before a newly launched process will pick up the variables.
This article also claims that Xcode will also pass these variables to a build phase script. I have not tested it yet but next time I restart my MacBook I will let you know if it worked.

Q: How do I set environment for all processes launched by a specific
user?
A: It is actually a fairly simple process to set environment variables
for processes launched by a specific user.
There is a special environment file which loginwindow searches for
each time a user logs in. The environment file is:
~/.MacOSX/environment.plist (be careful it's case sensitive). Where
'~' is the home directory of the user we are interested in. You will
have to create the .MacOSX directory yourself using terminal (by
typing mkdir .MacOSX). You will also have to create the environment
file yourself. The environment file is actually in XML/plist format
(make sure to add the .plist extension to the end of the filename or
this won't work).
