I have an question about the .exe log. I am using raspberry pi 4 module with Debian OS where I am running my c-program from the .service base auto-start .exe process. Which is running well So whenever raspberry Pi will restart my program will start automatic.That's fine but how do I see my print-f log from the terminal.
When I run exe with below line it will print the message but when this .exe running through the auto-services how can we check the log ?
Is there any linux command which will help to print run-time message. ?
root#raspberrypi: $./test.exe
it seems that you are using a systemd service unit, to run your binary.
if so, you can use:
journalctl -u <name>.service
(replace <name> with the actual name of your service)
sidenote:
do not use the .exe extension for your elf-binaries ("linux binaries").
.exe is an extension for PE32 files ("windows executables"), but Linux is perfectly capable of running a file with an arbitrary name (extensions have no meaning under linux).
so: executables typically have no extension at all, and you should get used to that: use test instead.

I am trying to run Python in my command prompt, but when I tried it tells me python is not recognised as an internal or external command, operable program or batch file
First of all, if you didn't installed python yet, install it! https://www.ics.uci.edu/~pattis/common/handouts/pythoneclipsejava/python.html
to run a program from inside the terminal (both in Windows and Linux) it need to be in the environment PATH variable - this way the terminal knows where the actual exe/elf is.
For example, if you installed the python in C:\Python37\python.exe, the PATH should contain that path.
Please read this article which explains how to add Python to the Windows PATH - https://geek-university.com/python/add-python-to-the-windows-path/

I'm trying to execute a bash script using ssh.
Say there is machine A and B. The bash script is on A and it has a command using a package installed locally in A. The package is not installed in B. I am trying to run the script from A when sshing to B. But I am constantly getting 'command not found'.
This is what I did:
ssh username#server 'bash -s' < local/path/to/file
I am wondering that is it because I don't have the package installed on B, the server? Is there any way that I can execute the script using B without having to install the package on it (my account do not have the write access to the directory)?
Theoretically you could, with lots of effort, embed the entire software in question in your script and pass that on the SSH standard input. But in the case of a properly secured server (which could even be a different platform) and a compiled program with lots of dependencies this could be anything from tricky to a multi-year project.
The trivial case of the "package" being just a single-line shell script without dependencies you could simply copy the contents of the script into your script. But the vast majority of cases are going to be orders of magnitude more difficult.
The commands passed to ssh inside the single quotes are executed on the remote host; therefore, those commands must exist on the remote host in order for them to execute there.

I am playing around with an open-source software, FSL. I have no problems running it on my Mac, where I am able to simply start it by typing fsl in the terminal.
However, I have no idea how to start the software on our school's HPC server. After logging into the school server via SSH, I type fsl as usual, and then
If 'fsl' is not a typo you can run the following command to lookup the package that contains the binary:
command-not-found fsl
-bash: fsl: command not found
Then, I navigate into the FSL installation directory (/data/apps/arch/Linux_x86_64/fsl/5.0.6) and type fsl. Still the same error. I have also tried
module load /data/apps/arch/Linux_x86_64/fsl/5.0.6
But this error occurs.
utility.c(2360):ERROR:50: Cannot open file '' for 'reading'
utility.c(2360):ERROR:50: Cannot open file '' for 'reading'
...
How should I load it properly and ultimately run it?
You have to call the executable with the correct path. You may either
cd to the directory containing the executable
prefix the executable's name with the path ./fsl
or (if you intend to use the executable frequently):
add the executable's path to your PATH-environment variable (export PATH=$PATH:/path/to/the/folder/containing/the/executable)
use the executable's name to call it (fsl).
or you place a symlink to your executable somewhere the $PATH already points to:
Check $PATH with echo ${PATH} (outputs a colon-separated list of directories the command line processor will look for your call)
If there is ~/bin in there, place a symlink: ln -s /path/to/your/executable/fsl ~/bin/fsl.
The command line processor will search the directories listed in ${PATH} for an executable called somecommand if you type somecommand.

I'm a user of Ubuntu 12.04 LTS and in a future a user of Ubuntu 14.04 LTS.
I have a problem, when I run Ubuntu my .bashrc script doesn't work unless I open the terminal.
This is a problem because, for example, the paths I write doesn't work unless I execute the programs from the terminal.
Are there an user config startup file for Ubuntu and not for the terminal?
P.D.:Maybe I don't explain very well, in other words, I'd like to execute mi scripts on Ubuntu startup without using the terminal.
Shell initialisation files (.profile, .bashrc, etc.) are intended for preparing the user's (interactive) environment.
For standalone scripts, it's better to make them independent from the environment, including
$HOME, $PATH, etc.
If you need to share code (functions, configuration) with other scripts, store that in a separate
shell library that you source from a known location, either through a fixed path or from a
path relative to the script's own location.
you can add the line below at the start of your script file
source ~/.bashrc
grep '/etc/bashrc' ~/.bashrc
if [ -f /etc/bashrc ]; then
. /etc/bashrc # --> Read /etc/bashrc, if present.
by default /etc/bashrc gets loaded when opening a console.
What are you trying to do - if you want to do something without it being executed as part of a console and more to do with system startup ? then you need to look into modifying existing service or adding a new service.
If this is related to when users ssh or connect it via console then its be bashrc file

I am using Linux Suse 10 and I am a complete noob when it comes to using it that's why I really needed some help.
The scenario is simple. I need to transfer some files from my linux server to a windows pc.
I already did this using FTP commands written inside a .scr file. Here's the content of my Upload.scr :
ftp -n 10.*.*.* <<SCRIPT
user administrator drowssap
cd TESTDIR
binary
lcd /path/of/the/txt/file/
put TESTUpload.txt
bye
SCRIPT
And then I would call it from linux Konsole using :
bash Upload.scr
It was actually working and could successfully transfer files to my windows pc. However, what I need is to transfer the files using "psftp".
The original code which works from windows-to-windows transfer is :
ProcessStartInfo PSI = new ProcessStartInfo("CMD.exe", "/C psftp " + UserName + "#" + IP + " -pw " + Password + " -b UpLoad.scr");
I needed to do the same to my linux-to-windows transfer (i.e. I needed to use psftp instead of just ftp or sftp).
Whenever I tried to type "psftp" on linux Konsole it would display the ff :
bash: psftp: command not found
I know there's something missing. What should I do first to make it work? Should I install some application or .exe file into my linux server?
I really need help.
Thank you very much in advance! :)
psftp is PuTTY's SFTP utility.
OpenSSH has one too, named simply sftp (without the p). It is very likely already installed on your Linux machine.
If you want to install PuTTY's psftp, you just need to run:
apt-get install putty-tools
or equivalent for your distribution.
