# ptee(1)

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

## 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)](/tee/1.md).

**ptee** can be used with **[pipexec(1)](/pipexec/1.md)** 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)](/pipexec/1.md): 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}"
```
