cat

cat [options ] [files ]

Read one or more files and print them on standard output. Read standard input if no files are specified or if - is specified as one of the files; end input with EOF . Use the > shell operator to combine several files into a new file; >> appends files to an existing file.

Options

-b

Like -n , but don't number blank lines. Solaris only.

-e

Print a $ to mark the end of each line. Must be used with -v .

-n

Number lines. Solaris only.

-s

Suppress messages about nonexistent files. (Note: On some systems, -s squeezes out extra blank lines.)

-t

Print each tab as ^I and each form feed as ^L . Must be used with -v .

-u

Print output as unbuffered (default is buffered in blocks or screen lines).

-v

Display control characters and other nonprinting characters.

Examples

                   Display a file

cat ch1 ch2 ch3 > all

     Combine files

cat note5 >> notes

        Append to a file

cat > temp1

               Create file at terminal; end with EOF

cat > temp2 << STOP
