cmus is a fast and flexible music player. It organizes your music by either musician or album title, and lets you load playlist files. You can also use cmus’ built-in search function to look for music in your /home directory and you can switch between several different layouts.

MOC (short for Music on Console) is a dual-pane music player that’s similar to cmus. The left pane lists the tracks in a folder, while the right pane contains the contents of a playlist file (if there is one in the folder).

If you want a quick and dirty way to play music files, then mpg123 and ogg123 are good options. I’ve lumped them together because both applications are very similar. In fact, the only difference between the two applications is the file formats they support.

ripit isn’t a music player, but it can help you feed your music player. It’s a script that works with a number of utilities and audio encoders—like cdparanoia, cdda2wav, Ogg Vobis, and LAME—to convert the tracks on a CD to files on your hard drive.

Termtosvg es una herramienta en linea de comandos que nos permite grabar nuestras sesiones de terminal en un entorno de animación SVG. Se trata de un formato soportado por los principales navegadores web (Chrome, Firefox que fue pionero a principios de esta década, Safari…), con la excepción del Edge de Microsoft, algo que a los linuxeros tampoco nos preocupa demasiado.

Creado en Python y con licencia libre BSD (3-Clause), termtosvg nos recuerda en diferentes aspectos a herramientas como script o el más reciente asciicinema, siempre una referencia a la hora de hacer demostraciones y tutoriales.

The ‘$’ character introduces parameter expansion, command substitution, or arithmetic expansion. The parameter name or symbol to be expanded may be enclosed in braces, which are optional but serve to protect the variable to be expanded from characters immediately following it which could be interpreted as part of the name.

When braces are used, the matching ending brace is the first ‘}’ not escaped by a backslash or within a quoted string, and not within an embedded arithmetic expansion, command substitution, or parameter expansion.
