Tee(3) User Contributed Perl Documentation Tee(3)NAMETee - Pure Perl emulation of GNU tee
VERSION
version 0.14
SYNOPSIS
# from Perl
use Tee;
tee( $command, @files );
# from the command line
$ cat README.txt | ptee COPY.txt
DESCRIPTION
The "Tee" distribution provides the ptee program, a pure Perl emulation
of the standard GNU tool "tee". It is designed to be a platform-
independent replacement for operating systems without a native "tee"
program. As with "tee", it passes input received on STDIN through to
STDOUT while also writing a copy of the input to one or more files. By
default, files will be overwritten.
Unlike "tee", "ptee" does not support ignoring interrupts, as signal
handling is not sufficiently portable.
The "Tee" module provides a convenience function that may be used in
place of "system()" to redirect commands through "ptee".
USAGE
"tee()"
tee( $command, @filenames );
tee( $command, \%options, @filenames );
Executes the given command via "system()", but pipes it through ptee to
copy output to the list of files. Unlike with "system()", the command
must be a string as the command shell is used for redirection and
piping. The return value of "system()" is passed through, but reflects
the success of the "ptee" command, which isn't very useful.
The second argument may be a hash-reference of options. Recognized
options include:
· stderr -- redirects STDERR to STDOUT before piping to ptee
(default: false)
· append -- passes the "-a" flag to ptee to append instead of
overwriting (default: false)
LIMITATIONS
Because of the way that "Tee" uses pipes, it is limited to capturing a
single input stream, either STDOUT alone or both STDOUT and STDERR
combined. A good, portable alternative for capturing these streams
from a command separately is IPC::Run3, though it does not allow
passing it through to a terminal at the same time.
