Bash code to create named Pipe
Guy's,

I need help with creating a pipe, I found this code online but not exactly sure what different parts are doing.

Will someone be able to help me with explaining what code is doing?

Also what I want is to have everything the same directory. Meaning I am working in directory:
Quote:
Home/users/Bashwork/Testing
I want to keep everything in Testing directory.

Code:
#!/bin/bash

  
  HERE=`uname -n`    # Will I be able to add the directory here 
  THERE=bilbo         # What is this creating?
  echo "starting remote backup to $THERE at `date +%r`"
  # ==> `date +%r` returns time in 12-hour format, i.e. "08:08:34 PM".
  
  e
  rm -rf /pipe
  mkfifo /pipe       # ==> Create a "named pipe", named "/pipe".
  
 #What is this doing too?

  su xyz -c "ssh $THERE \"cat >/home/xyz/backup/${HERE}-daily.tar.gz\" < /pipe"&
  cd /

#This too?

  tar -czf - bin boot dev etc home info lib man root sbin share usr var >/pipe


  exit 0

Thanks

will a named pipe always be size 0 on filesystem?

I did cat < myFile >> myPipe I was hoping that if I did ls -l, myPipe would now be holding the contents of myFile, and would be the same size. But it was 0. Also strange was that when I did the command above, cat did not return control back to the shell. Why? thanks (4 Replies)

       Most of this was part of Parrallel::Runner intended for use in the Fennec project. Fennec is being broken into multiple parts, this is one
       such part.

FENNEC PROJECT

       This module is part of the Fennec project. See Fennec for more details.	Fennec is a project to develop an extendable and powerful testing
       framework.  Together the tools that make up the Fennec framework provide a potent testing environment.

       The tools provided by Fennec are also useful on their own. Sometimes a tool created for Fennec is useful outside the greator framework.
       Such tools are turned into their own projects. This is one such project.

	 The primary Fennec project that ties them all together.
