.IX Title "CAT 1"
.TH CAT 1 "2001-06-06" "perl v5.20.0" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.
.if n .ad l

.SH "NAME"
cat \-\- concatenate and print files.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
cat [\-benstuv] [file ...]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIcat\fR reads and prints the files in order they are given. If no files
are given, \fIstandard input\fR is processed. A lone dash represents 
\&\fIstandard input\fR as well.
.SS "\s-1OPTIONS\s0"
.IX Subsection "OPTIONS"
\&\fIcat\fR accepts the following options:
.IP "\-b" 4
.IX Item "-b"
Number all the non blank lines, starting at 1.
.IP "\-e" 4
.IX Item "-e"
Print a dollar sign (\fB$\fR) at the end of each lines. Implies \fI\-v\fR.
.IP "\-n" 4
.IX Item "-n"
Number all the lines, starting at 1.
.IP "\-s" 4
.IX Item "-s"
The \fIsqueeze\fR option. Sequential empty lines are squeezed into a 
single empty line.
.IP "\-t" 4
.IX Item "-t"
Display tabs as \fI^I\fR. Implies \fI\-v\fR.
.IP "\-u" 4
.IX Item "-u"
Unbuffer output.
.IP "\-v" 4
.IX Item "-v"
Display non-printable characters in a printable way. Characters in the
range \fI\e000\fR \- \fI\e037\fR, with the exception of tabs and linefeeds, are
printed as \fI^X\fR, where \fIX\fR is the symbol \fI\e0100\fR higher. \fI\s-1DEL\s0\fR is
printed as \fI^?\fR. Characters whose highest bit is set are printed as
\&\fIM\-\fR, followed by the representation of the character with the high
bit stripped.
.SH "ENVIRONMENT"
.IX Header "ENVIRONMENT"
The working of \fIcat\fR is not influenced by any environment variables.
.SH "BUGS"
.IX Header "BUGS"
\&\fIcat\fR has no known bugs.
.SH "STANDARDS"
.IX Header "STANDARDS"
This \fIcat\fR implementation is compliant with the \fB\s-1IEEE\s0 Std1003.2\-1992\fR
specification, also known as \fB\s-1POSIX.2\s0\fR.
