Why do command names and filenames usually not have embedded SPACEs? How would you create a filename containing a SPACE? How would you remove it? (This is a thought exercise, not recommended practice. If you want to experiment, create a file and work in a directory that contains only your experimental file.)
What will be an ideal response?
From a command line, when you want to refer to a file whose name con-
tains an embedded SPACE, you must quote the SPACE. A SPACE is a special
character to the shell; it typically separates tokens or words on the com-
mand line. Because it is tedious to refer to this type of file, most filenames
do not include SPACEs.
You can remove a file whose name contains a SPACE by quoting the SPACE:
$ rm dumb\ filename
or
$ rm "dumb filename"
