world% cat filename
cat reads each file in sequence and writes it on the standard output.
Thus,
world% cat file
prints the contents of file on your terminal, and
world% cat file1 file2 >file3
concatenates file1 and file2, and writes the results in file3. If no
input file is given, or if the argument - is encountered, cat reads from
the standard input. cat processes supplementary code set characters
according to the locale specified in the LC_CTYPE environment variable.
Redirecting the output of cat onto one of the files being read will cause
the loss of the data originally in the file being read. For example,
world% cat file1 file2 >file1
causes the original data in file1 to be lost.
The -v option causes non-printing characters (with the exception of
tabs, newlines and form-feeds) to be printed visibly.
The -vt option causes tabs to be printed as ^I's and formfeeds to be
printed as ^L's.
The -ve option causes a $ character to be printed at the end of each
line (prior to the new-line).
