Linux Tutorial Series – 57 – Brace expansion

Here is the video version, if you prefer it:

Brace expansion is used to pass multiple arguments to a command. (Barrett, 2016)⁠ An example:

mislav@mislavovo-racunalo:~/Linux_folder$ echo my{File1,File2,File3}

myFile1 myFile2 myFile3

So the shell performed its expansion and I have 3 filenames because of that. Note that there are no spaces between the commas and the next letter. If I put a space, I would get:

mislav@mislavovo-racunalo:~/Linux_folder$ echo my{File1, File2, File3}

my{File1, File2, File3}

Useful to know.

Hope you learned something new!
