| ubuntutestingbot | [telegram] <GalacticLion7> Does anyone know how to write a text file with multiple lines in a shell script without using \n? | 03:45 |
| ubuntutestingbot | [telegram] <philipz> i've seen it done with these << arrows before, but not sure exactly how its done (re @GalacticLion7: Does anyone know how to write a text file with multiple lines in a shell script without using \n?) | 04:20 |
| ubuntutestingbot | [telegram] <philipz> or more accurately not sure where to find it, but do know how its done, as it works the same way in php | 04:23 |

| ubuntutestingbot | [telegram] <GalacticLion7> does it exit a shell script if I use EOF? (re @MrkiMike: These > before each number are because I did it directly in shell, so I had to type EOF to 'finish') | 10:31 |
| ubuntutestingbot | [telegram] <MrkiMike> nop | 10:37 |
| ubuntutestingbot | [telegram] <MrkiMike> here is an example: https://stackoverflow.com/questions/2500436/how-does-cat-eof-work-in-bash | 10:37 |
| ubuntutestingbot | [telegram] <MrkiMike> or: https://www.cyberciti.biz/faq/using-heredoc-rediection-in-bash-shell-script-to-write-to-file/ | 10:37 |
| ubuntutestingbot | [telegram] <MrkiMike> But... better question from my side would be - what are you trying to do/achieve? Maybe there is a better way. | 10:38 |
| ubuntutestingbot | [telegram] <GalacticLion7> I was trying to make a shell script that sets up my Nginx reverse proxy configs (re @MrkiMike: But... better question from my side would be - what are you trying to do/achieve? Maybe there is a better way.) | 10:45 |
| ubuntutestingbot | [telegram] <MrkiMike> Are those parametrized somehow? | 10:46 |
| ubuntutestingbot | [telegram] <Zachariah> nginx has its own configuration files. You set up reverse proxy in the config. Were you looking for a way to edit the config with sed from a bash script? | 10:47 |
| ubuntutestingbot | [telegram] <GalacticLion7> They are (re @MrkiMike: Are those parametrized somehow?) | 10:48 |
| ubuntutestingbot | [telegram] <GalacticLion7> Not edit, just create new sites in /etc/nginx/sites-available (re @Zachariah: nginx has its own configuration files. You set up reverse proxy in the config. Were you looking for a way to edit the config with sed from a bash script?) | 10:48 |
| ubuntutestingbot | [telegram] <Zachariah> Oh and you need a way to output multi-line. | 10:49 |
| ubuntutestingbot | [telegram] <GalacticLion7> Not edit, just create new files in /etc/nginx/sites-available (edited) (re @Zachariah: nginx has its own configuration files. You set up reverse proxy in the config. Were you looking for a way to edit the config with sed from a bash script?) | 10:49 |
| ubuntutestingbot | [telegram] <GalacticLion7> Does export work in scripts? | 10:50 |
| ubuntutestingbot | [telegram] <MrkiMike> it does, but... it might not do what you expect | 10:50 |
| ubuntutestingbot | [telegram] <MrkiMike> @GalacticLion7 maybe taking a look at ansible would be better - it's a tool designed to parametrize setups/deployments, and it's ideal for small to medium sized things | 10:51 |
| ubuntutestingbot | [telegram] <Zachariah> You can use: | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> cat > file.conf << EOL | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> line 1, abc | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> line 2, def | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> line 3, ghi | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> EOL | 10:52 |
| ubuntutestingbot | [telegram] <Zachariah> Which is just the heredoc approach. | 10:52 |
| ubuntutestingbot | [telegram] <GalacticLion7> Learning curve? (re @MrkiMike: @GalacticLion7 maybe taking a look at ansible would be better - it's a tool designed to parametrize setups/deployments, and it's ideal for small to medium sized things) | 10:55 |
| ubuntutestingbot | [telegram] <GalacticLion7> I need to do something like | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> bash | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> export Key="Your Key" | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> export Email="Your Email" (re @MrkiMike: it does, but... it might not do what you expect) | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> I need to do something like | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> export Key="Your Key" | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> export Email="Your Email" (edited) (re @MrkiMike: it does, but... it might not do what you expect) | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> The solution above was using EOF, what is the difference? (re @Zachariah: You can use: | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> cat > file.conf << EOL | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> line 1, abc | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> line 2, def | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> line 3, ghi | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> EOL) | 10:58 |
| ubuntutestingbot | [telegram] <GalacticLion7> I would also like to append to crontab | 10:59 |
| ubuntutestingbot | [telegram] <Ron> Greetings. I have Nividia GTX 1050ti. No audio from HDMI port. Can anybody help? | 11:15 |
| ubuntutestingbot | [telegram] <Zachariah> The EOF approach is generally used when entering data manually. The EOL method gives you more granular control of your lines. For instance, you could do something like: | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> conf1 = "abc" | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> conf2 = "def" | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> conf3 = "ghi" | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> cat > file.conf <<EOL | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> line 1, ${conf1} | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> line 2, ${conf2} | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> line 3, ${conf3} | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> line 4 this is the end of the config | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> EOL (re @GalacticLion7: The solution above was using EOF, what is the difference?) | 11:28 |
| ubuntutestingbot | [telegram] <Zachariah> Are you using Nouveau or the nVidia proprietary driver? If the latter, you may need to play around with your sound settings until you find the correct output. (re @Ron: Greetings. I have Nividia GTX 1050ti. No audio from HDMI port. Can anybody help?) | 11:29 |
| ubuntutestingbot | [telegram] <Ron> using the Nvidia 440 driver. how to config the sound settings? | 11:39 |
| ubuntutestingbot | [telegram] <Zachariah> System Settings -> Sound | 11:39 |
| ubuntutestingbot | [telegram] <Zachariah> Sometimes you get multiple HDMI audio outputs. You just need to select each one and test to figure out which one is correct. | 11:41 |
| ubuntutestingbot | [telegram] <Ron> I did use the settings menus to choose the Nvidia card for audio. But no sound. | 11:41 |
| ubuntutestingbot | [telegram] <Zachariah> Was there only one or multiple like HDMI 0, HDMI 1, etc.? | 11:42 |
| ubuntutestingbot | [telegram] <Ron> only 1. the choice is the internal audio or the Nividia card, simple! | 11:43 |
| ubuntutestingbot | [telegram] <Zachariah> Have you tested HDMI audio with another source? Just to be sure? | 11:44 |
| ubuntutestingbot | [telegram] <Ron> well, the source is the HDMI port in the Nvidia card in my desktop. I have a HDMI2VGA converter with vga and analog audio jack, and my stereo is plugged into this converter via the 3.5 audio jack. no sound. I have not yet tried to go from Nvidia HDMI directly into another coimpatiblbe device, as I have none. The Nvidia and converter are brand new. | 11:49 |
| ubuntutestingbot | [telegram] <Ron> [please excuse typos]. | 11:50 |
| ubuntutestingbot | [telegram] <Zachariah> I see. So HDMI is 2-way communication. The video card needs to receive information from the device it is attached to. A TV or monitor should allow the video card to know it is a sound source. But a custom device like your converter may not communicate correctly. | 11:53 |
| ubuntutestingbot | [telegram] <Ron> oh, this I had not realised. Could be the device, indeed. Thanks for this info and your kind replies. I will investigate this further. Bye for now. | 11:56 |
