Tee - Pure Perl emulation of GNU tee
# from Perl
tee( $command, @files );
# from the command line
$ cat README.txt | ptee COPY.txt
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.
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 isnt very useful.
The second argument may be a hash-reference of options. Recognized options
stderr redirects STDERR to STDOUT before piping to ptee (default: false)
append passes the -a flag to ptee to append instead of overwriting
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
