Debajyoti's questions

I have a Fortran Executable file named chuck in the folder /home/debajyoti/chuckDir/.

The program chuck do is like, it takes an input file inputfile.txt and an output file outputfile.txt and calculates on the data from inputfile.txt and writes the output in the file outputfile.txt.

I to do all these calculations with the following steps in Ubuntu Terminal:

~$ cd chuckDir

~/chuckDir$ ./chuck <inputfile.txt> outputfile.txt

NOW I want to run chuck and do all these within a Python Script. The purpose of the Python3 Script is, it takes the data from the outputfile.txt to Plot. Now my question is how can I run chuck within the Python3 Script itself?

When I was connecting Headphone in the front panel port of CPU I couldn't hear any sound, actually it couldn't detect the headphone. But when I'm connecting it in the back panel port it can detect. And sound box is also working fine from the back panel, but not from front panel. This problem occurs only when I'm using Ubuntu 18.04, but in Windows 10 Pro it works fine from both of the panels (I use Win 10 & Ubuntu 18.04 in dual boot). My CPU config is 3.5GHz Intel G-4560, H110M PRO VH Plus MSI motherboard, Intel HD 610 GPU. Is the problem because of drivers? If so then how fix this (or how to install it) ? Or any kind of suggestion how to fix it. Thanks in advance!

I can't compile a C file in Ubuntu 18.04.

In terminal I used this command: $ gcc -o abc.o abc.c -lm, but it says that gcc is not found.

This exact command can compile a C program in Ubuntu 16.04 (which I used earlier).

Can anyone help how to fix this? As far as I knew that gcc was the compiler by default in Ubuntu. But in 18.04 things seem different. What happened to 18.04? Thanks!

How to install Ubuntu 18.04 alongside Windows 10?

I have tried different process to install Ubuntu 18.04 in my PC in dual boot mode alongside Windows 10. But it turned out that most of the process didn't worked for my PC. My PC's configuration is 500 HDD, 3.5GHz Intel processor, 4GB RAM, 1GB Intel graphics & supports both BIOS & UEFI.

In Ubuntu 16.04 LTS the application Browser is not working (Firefox is working fine). When I open it, a transparent box opens up with the title bar named Browser & nothing shows. The background can be seen through that opened window. The system hangs out completely ( that’s why I can’t take a screenshot and attach here) and I have to press the power button to switch/restart the system. Any kind of suggestion how to fix this?
