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

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

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.

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

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}"
