cat

Runs on:

QNX Neutrino

Options:

-c

Compress sequences of multiple newline characters into single newlines.

-n

Print line numbers, but don't restart the number for each new file.

-r

Print line numbers, restarting the number for each new file.

-u

Write unbuffered output. Data from the input file(s) is written to the standard output without delay as each file is read.

-w

Wait at the end of a line for 100 ms for each occurrence of -w.

file

The pathname of an input file. If no files are specified, standard input is used. If a file is the dash character (-), cat reads from standard input at that point in the sequence.

Description:

The cat utility reads files in the order you specify and writes their contents to standard output.

Examples:

Write the contents of myfile to standard output:

cat myfile

Concatenate doc1 and doc2 and write the result to doc.all:

cat doc1 doc2 > doc.all

Exit status:

0

All input files were output successfully.

>0

An error occurred.

Caveats:

Because of the shell language mechanism used to perform output redirection, a command such as:

cat doc doc.end > doc

causes the original data in doc to be lost. The file doc is opened for write by the shell, and therefore truncated to zero length, before cat is executed.
