since yesterday I've been trying to run a command in my script called sed it processes a text and don't tell me that there is any errors but when I check inside the file it just suppresses the text that was supposed to be replaced.



Can someone help me with this ?



Here is my code :



#!/bin/bash
echo "Bienvenue dans l'outils d'ajout à la base de données sur les Animés"
echo "Pour commencez veuillez taper le titre de l'animé dans ce format-ci"
echo "exemple_pour_tester ; Sans majuscules ni espaces"
cat ~/mal-project/anime_template >> ~/mal-project/sources/anime-list
 echo -n "Mal-Database ->"
 read $titre
 echo "processing..."
 sed -i "s/titre/$titre/" ~/mal-project/sources/anime-list





command-line bash sed

    Please have a look at "How to create a Minimal, Complete, and Verifiable example." Also, I doubt that read $titre what you want. Lastly, there is no way to tell whether the sed command does what you want without having a sample input file and your desired output file.

  • I tried the command manually and it worked perfectly. It doesn't always need and in and out input

  • In this case at least, that is not true. Without your sample input, there is no way of knowing whether you actually have the curly braces in your input file.

There are two major issues in your script.




  1. to read something from stdin and put it in a variable called titre you need



    read titre


    (without a preceeding $). This will put your input into
    the variable $titre.




  2. To replace the literal word titre with the content
    of the variable $titre you need



    sed -i "s/titre/$titre/" ~/mal-project/sources/anime-list


The curlies ($titre vs. $titre) are only needed to make clear where a variable ends if the situation is ambigious. Consider you want to replace the literal titre with the content of the variable $titre plus the text deux. The naive approach would be



s/titre/$titredeux/


But here titre would be replaced with nothing (empty string) because there is no variable $titredeux. Hence, we write



s/titre/$titredeux/


instead to make clear that the variable is actually just $titre.

            How to enroll fingerprints to Ubuntu 17.10 with VFS491

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
