Quoting Special Characters in Filenames (Unix Power Tools, 3rd Edition)
27.14. Quoting Special Characters in Filenames
If
you want to work with files
that have spaces or special characters in the filenames, you may have
to use quotes. For instance, if you wanted to create a file that has
a space in the name, you could use the following:
/dev/null Section 43.12
% cp /dev/null 'a file with spaces in the name'
Normally, the shell uses spaces to
determine the end of each argument. Quoting (Section 27.12, Section 27.13) changes that -- for example, the
cp command above has only two arguments. You can
also use a backslash (\) before a special
character. The example below will rename a file with a space in the
name, changing the space to an underscore ( _ ):
% mv a\ file a_file
Using the same techniques, you can deal with any character in a
filename:
% mv '$a' a
At worst, a space in a filename makes the
filename difficult to use as an argument. Other characters are
dangerous to use in a filename. In particular, using
? and * in a filename is
playing with fire. If you want to delete the file
a?, you may end up deleting more than the single
file.
