These scripts can be useful when dealing with images, videos, files in general, FFMPEG, conda, etc. I think some features are missing that is why these scripts are meant for. Or just because I am too lazy (or stupid) to remember the syntax, so I prefer to write it once and only once ^^. Or I might be misusing conda, or did not found the proper explanations in the documention.
You can run them in your terminal.
Please make the scripts executable. For instance :
chmod +x ffmpeg_compress.sh
Then, assuming you are in the folder containing the script :
./ffmpeg_compress.sh
for this example, this will compress all video files ("mp4", "avi", "mkv", "mov") with bitrate 500k. If you want another bitrate, please pass it as argument.
To be able to call these scripts in whatever terminal at whatever current directory, I invite you to create some aliases. There are several ways of doing it. Here is mine : I have a .bash_aliases file close to my .bashrc file (see some explanations on askubuntu). And I have declared some aliases, for example
alias ffmpeg_compress='~/ffmpeg_compress.sh'
Another way is to copy the script info a function you may declare like this :
conda_find_package() {
COPY THE SCRIPT CODE HERE
}
