NAME

cat − concatenate and print files

SYNOPSIS

cat [ −u ] [ −s ] file ...

DESCRIPTION

Cat reads each file in sequence and writes it on the standard output.  Thus:

cat file

prints the file, and:

cat file1 file2 >file3

concatenates the first two files and places the result on the third. 

If no input file is given, or if the argument − is encountered, cat reads from the standard input file.  Output is buffered in 512-byte blocks unless the −u option is specified.  The −s option makes cat silent about non-existent files.  No input file may be the same as the output file unless it is a special file.
