You can see that there are two possibilities here; you would need to choose which
of the two versions of sort met your requirements. In either possibility, however, we
have the option:
–o outfile
This option tells the sort command where to save its sorted output. The form of the
option is –o, followed by a space, followed by outfile. In a command format,
anything appearing in italic serif font is a placeholder for information that you are
expected to supply. Sometimes after the format, the kind of information expected in
place of the placeholder is explained. In our sort example, outfile stands for the
name of a file where you want sort to store its output. For example, if you wanted
to store the output in the file sorted.dat, you would specify:
sort -o sorted.dat
(followed by the rest of the command).
The format for sort also contains an option of the form:
–tchar
This is similar to the option form we were just discussing, except that there is no
space between the –t and char. char in italics is a placeholder; in this case, it
stands for any single character. If you want to use the –t option for sort, you just
type –t followed immediately by another character, as in:
sort -t:
In this case, we use a colon (:) in the position of the placeholder char.
The end of the sort format is:
[file ...]
This means a list of one or more filenames; the ellipsis (....) stands for repetitions of
whatever immediately precedes it. Since there are square brackets around the
previous list, you can omit the list if you like.
The format of ls ended in:
[pathname ...]
As you might guess, this means that an ls command can end with an optional list of
one or more pathnames. What’s the difference between this and our sort example?
A pathname (specified with pathname) can be the name of either a file or a
directory; a filename (specified with file) is always the name of a file.
