Pycharm - command line to build cache/index for a project - command-line

In brief
Opening a PyCharm project takes long time due to index/cache build process - to speed it up, I'm looking for how to call PyCharm to build that via a command line.
This question is also posted as PyCharm ticket here
In details
PyCharm index build takes long time to finish which is quite annoying when start working with project.
I want that run to be executed via command line so that I can run them at night e.g. 03:00 AM. That will help us to open the project quickly since the cache/index has been prepared by our scheduled command-line above.
So the question is, what is the command to do so?
My google search on this topic and on our site is empty so I asked here.
p.s.
We can open a PyCharm project via command line as discussed here; though I cannot find an option for building index/cache.
$ charm --help
Usage:
/usr/local/bin/charm -h | -? | --help
/usr/local/bin/charm [project_dir]
/usr/local/bin/charm [-l|--line line] [project_dir|--temp-project] file[:line]
/usr/local/bin/charm diff <left> <right>
/usr/local/bin/charm merge <local> <remote> [base] <merged>

This is the workaround for now on my Ubuntu Desktop 16.04
Please make sure charm command is installed on your system to call reload_pycharm_projects bash command as defined below.
function reload_pycharm_projects() {
cd $path_to_code_home
echo 'Running PyCharm...'
charm &
sleep 16 # wait 16s for PyCharm window to be opened; put in the time suitable on your machine
# open pycharm projects - list all projects of your interest below
echo 'Loading projects...'
charm p1
charm p2
charm p3
sleep 90 # wait 90s for all project load & index/cache refreshed; put in more time as you want
cd --
echo 'Closing Pycharm...'
kill -9 $(ps x | grep -E .+java.+PyCharm | awk '{print $1}') # kill pycharm window
exit
}

How to setup zsh personal config (.dotfiles/zsh/zshrc) at every start on Raspberry Pi 400

I am training myself on Linux with a Raspberry Pi 400 (OS: Raspbian) and I would like to setup my personal config file for apps (notably the Terminal in Zsh). I am able to setup my config onto the terminal with the following:
$ cd .dotfiles
$ ./export.sh
$ cd zsh/
$ source ./zshrc
The problem comes when I quit the terminal or if I open a new terminal or if I reboot the computer, the config is not "saved".
I am not an expert, but for changing bash to zsh and maintaining it as default shell language, I did the following:
$ nano /etc/passwd
and changed the following line from :
pi:x:1000:1000:,,,:/home/pi:/bin/bash
to:
pi:x:1000:1000:,,,:/home/pi:/bin/zsh
This move managed to get me zsh from start every time now. I am wondering if i can directly source my .zshrc with the same technique ... Or would you have any better idea?
I would like to avoid repeating the sourcing steps at every start in the terminal ...

Terminal prompt disappears when a named pipe is used

I'm trying to use named pipes in a project. I have two terminals open, Terminal A and Terminal B.
In terminal A, I issued this command:
mkfifo myFifo && tail -f myFifo | csh -s
It seems as if standard out is being redirected somewhere else, though, because my prompt disappears and some commands aren't reflected in terminal A.
For example, if in terminal B I begin a python session via issuing echo "python" > myFifo, then echo "print 'Hello, World'" > myFifo, I don't see Hello, World in terminal A.
However, if I issue echo ls > myFifo within terminal B, I see the correct output from ls in terminal A.
Does anyone know why sometimes the output appears and sometime it doesn't?
I'm running on CentOS 6.6
Thanks,
erip
You read from the FIFO with csh, if you start an interactive Python shell in csh, then it won't be reading from the FIFO because it's busy running python.
Python doesn't somehow automagically do a REPL on the FIFO. How should it even know about the FIFO? It has no knowledge of it.
You could, perhaps, tell Python to read commands from the FIFO with something like:
>>> import os, sys, time
>>> fifo = open(os.open('myFifo', os.O_NONBLOCK), 'r')
And then:
$ echo 'print(42+5)' > ! myFifo
Will give you:
>>> eval(fifo.read())
47
Perhaps there's also a way to tell Python to read commands from myFifo by overwriting sys.stdin, but I can't get that working in my testing.
It's a bit unclear to me what exactly you're trying to achieve here, though. I suspect there might be another solution which is much more appropriate to the problem you're having.

OpenSuse - Command for Beep Sound (System Bell)

I have a source code that runs perfectly fine on Ubuntu, it does some copumtations, and at some points it beeps like this
system("beep -f 400 -l 500");
On Ubuntu I had to do
apt-get install beep
However, I migrated to OpenSuse (not my choice) and now I get this message "sh: beep: command not found", as the command and package are obviously different.
Does anybody know hot to trigger the system beep sound and define the duration and frequency? I have been able to find only one way to change the parameters
setterm -bfreq 500 -blength 500
, but no way to actually trigger the system bell (beep). The following things don't work
echo ^G
echo -e "\a"
PS - the system Bell is enabled at
Configure Desktop -> Application and System Notifications -> System Bell
and you can actually play with this
So, I did what #fvu proposed.
However, one needs to have sudo rights, to do so, otherwise (e.g. at my work-place we don't have sudo rights) there is this output message
Could not open /dev/tty0 or /dev/vc/0 for writing open: No such file or directory
In this case, you should:
sudo chmod 4755 /usr/bin/beep
as proposed here
I noticed that on my OpenSuse 12.3 system, the bell is working in xterm or gnome-terminal, but not in konsole or xfce4-terminal.
If the same applies to your system, then maybe a work-around could be creating a shell script called "beep" which calls xterm and rings the bell:
#!/bin/sh
xterm -e "echo -e '\a'; sleep 1"

"time" command in Cygwin works, but not in NetBean

I can do this in Cygwin, adding time Command
USER#USER_PC ~
$ time ./HelloWorld
shows smthing like
Hello World!!!
real 0m0.270s
user 0m0.270s
sys 0m0.270s
I've deployed an similar C/C++ Project #NetBean7.2 #Win 7.
It shows error message at Run time, Only when I add time Command ,like:
time "${OUTPUT_PATH}"
,at the Text Field of Projcet_file-> R_Click -> Properties -> Run -> Run_Command:
,and default value ${OUTPUT_PATH} only.
Error message is
C:\ProjectFolder\time does not exist or is not an executable
,seems that NetBean consider time as an excutable
Any better ways to solve it??
full command to bash needs to be in quotes if calling from cmd shell
bash -c "time ls"
time is a builtin command of bash. On my cygwin installation the proper command is:
c:\cygwin\bin\bash -c time
You have to adjust the path to bash.

Cygwin - run script silenty from "run command"

I have script lets say:
C:\foo.bsh
I want to be able to run this command via the windows run command:
Start -> Run
Windows Key + R
and type something small like 'foo' and hitting return.
However, I do not want a cmd prompt to be visible. This script does some preprocessing for an IDE. I do not want the cmd prompt to be open for the lifetime of the IDE process.
I have tried:
1) Creating a bat file with the following contents:
c:\cygwin\bin\bash --login "C:\foo.bsh" (this fails because it keeps a cmd open)
2) Converting the above bat file to an exe using bat_2_exe_converter (does not make the cmd silent)
thoughts?
EDIT: The solution so far suggests something to type from an actual cygwin shell. I am trying to get a faster solution by having something short I can type in the Windows run command. Also, the nohup command; exit doesn't automatically kill the box - however I can manually kill it without killing the IDE process. The run command accepts shortcuts (.lnk's), bat's, exe's.
Try the run.exe command of cygwin. It is a big install, a complete unix environment for your Windows machine. Suppose you installed it at c:\cygwin\.
No mystery, just run c:\cygwin\bin\run.exe <your command here> and you will have your no dos window execution.
You can run it from any DOS window (run cmd.exe from the start menu). You don't need to run it from cygwin.
To make it easier, append C:\cygwin\bin to your %PATH% env var (My Computer → Properties → Advanced → Environment Variables) (Kudos to Felipe Alvarez comment).
Now you can just type
c:\cygwin\bin\run.exe "C:\foo.bsh"
You must create a link in your Start Menu with this command so will be able to run it with Win-R.
Here is the man page of the runcommand:
$ man run
RUN(1) run 1.3.0 RUN(1)
NAME
run - start programs with hidden console window
SYNOPSIS
run [ -p path ] command [ -wait ] arguments
runcommand [ -p path ] [ -wait ] arguments
DESCRIPTION
Windows programs are either GUI programs or console programs. When
started console programs will either attach to an existing console
or create a new one. GUI programs can never attach to an exiting con‐
sole. There is no way to attach to an existing console but hide it if
started as GUI program.
run will do this for you. It works as intermediate and starts a pro‐
gram but makes the console window hidden.
With -p path you can add path to the PATH environment variable.
Issuing -wait as first program argument will make run wait for program
completition, otherwise it returns immediately.
The second variant is for creating wrappers. If the executable is
named runcommand (eg runemacs), run will try to start the program (eg
emacs).
EXAMPLES
run -p /usr/X11R6/bin xterm
run emacs -wait
runemacs -wait
run make -wait

You can use either...
c:\cygwin\bin\bash -l /path/to/script_to_interpret.sh
...or...
c:\cygwin\bin\bash -l -c /path/to/executable_script.sh
Note: the -l flag tell bash to "act as if it had been directly invoked by login" and use Bash Startup Files. This is important in that it sets your $PATH and other things you rely on when you launch a cygwin terminal. If you don't include -l or --login you will get "command not found" when you try to call anything except of a bash builtin.
The difference between the 2 is like the difference between doing...
bash script_to_interpret.sh
...and...
./executable_script.sh
...in *nix. The former interprets the script using bash. The latter executes the script (only if it has chmod +x executable_script.sh) and interprets it according to its "shebang" line. The latter method is also what you want to do if your executable is not a script at all, like a *nix binary compiled from source.)
It has been bugging me for a while I couldn't find the solution for this, but I finally got the right mix together.
You can simply do the following if you have cygwin on your PATH:
run bash test.js
If cygwin is not on your path, you can do this:
c:\cygwin\bin\run.exe -p /bin bash test.js
If you are looking for more control over the created window (maximize, etc) it looks like you can use cygstart also.

As the terminal can't close while your script is still running, try the command:
"nohup C:\foo.bsh; exit"
This way your script will be backgrounded and detached from the terminal, and it should exit quickly so the terminal goes away. I think that the window may still 'flash' with this approach, but the results should be better than what you're getting.
I'm running Cygwin64 and the xwin server link points to:
C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe
This creates an icon AND a notification on the taskbar. I don't like that. The icon is rather useless, the notification has all your menu options from .XWinrc.
So... I wrote a .vbs script to silently run this command and make the icon go away:
Set objShell = CreateObject("WScript.Shell")
objShell.Run("C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe"), 0
Another imperfect possibility is to run the script via a shortcut and set the shortcut's Run option to "minimized".
Go to the directory where you have installed cygwin(on my machine it is c:/cygwin64/bin)
Once there simply type "bash.exe"
