cat - concatenate files
cat [-] [file...]
Description
The cat command reads each file in sequence and writes it on the standard output. The following command prints the file to standard output:
cat file
The following command concatenates two files into a third:
cat file1 file2 >file3
If no file is given, or if minus (-) is given as an argument cat reads from the standard input.
Caveat
Beware of cat a b >a and cat a b >b, which destroy input files before reading them.
