cat
: Concatenate and write files
cat
copies each file (`-' means standard input), or
standard input if none are given, to standard output. Synopsis:
cat [option] [file]... |
The program accepts the following options. Also see 2. Common options.
cat
on MS-DOS/MS-Windows uses binary mode only when
standard output is redirected to a file or a pipe; this option overrides
that. Binary file I/O is used so that the files retain their format
(Unix text as opposed to DOS text and binary), because cat
is
frequently used as a file-copying program. Some options (see below)
cause cat
to read and write files in text mode because in those
cases the original file contents aren't important (e.g., when lines are
numbered by cat
, or when line endings should be marked). This is
so these options work as DOS/Windows users would expect; for example,
DOS-style text files have their lines end with the CR-LF pair of
characters, which won't be processed as an empty line by `-b' unless
the file is read in text mode.
