ptee

NAME

ptee − piped tee: read from one file descriptor and copy to many

SYNOPSIS

ptee [−h] [−r infd] outfd1 [outfd2 ...]

DESCRIPTION

ptee reads from one file descriptor (0 / stdin by default) and copies everything to all given output file descriptors. ptee is a piped version of tee(1).

ptee can be used with pipexec(1) to fit the output of one command into many other commands.

OPTIONS

−h

print help and version information

−r infd

use the given infd as input file descriptor. If this is not specified, 0 (stdin) is used.

EXAMPLES

Duplicate all data from stdin to stdout, stderr and fd 7:
ptee 1 2 7

The command
tee output.txt
is equivalent to the shell command
ptee 5 5>output.txt

Using pipexec(1): count all files in the file system and additionally count only those that have a uppercase ’A’ in their name. The file system will be scanned only once. No temporary files are generated.
pipexec [ LS /bin/ls −R / ] [ PTEE /usr/bin/ptee 3 4 ] \
[ WC1 /usr/bin/wc −l ] [ GREP /bin/grep A ] \
[ WC2 /usr/bin/wc −l ] "{LS:1>PTEE:0}" "{PTEE:3>WC1:0}" \
"{PTEE:4>GREP:0}" "{GREP:1>WC2:0}"

SEE ALSO
