# \_\_piper(8)

## NAME

**\_\_piper - create commands pipes without the overhead of shells**\

**This program has no potential use for administrators or users**\
 **This program is part of afbackup-client**

## SYNOPSIS

**\_\_piper \[ command \[ args \] \[ "\|" command \[ args \] \[ "\|" ... \] \] \]**

## DESCRIPTION

**This program simply gets one or more commands separated by the pipe symbol "\|" as arguments. When called from a shell command line or in any situation, where the whole command is interpreted by a shell, the bar "\|" has to be escaped from interpretation, either by preceding** **it with a backslash "**

**This program is part of afbackup-client**

## EXAMPLES

**The arguments are chained (separated by single spaces each) and then separated at word boundaries.**  **If an argument should contain whitespace, it must be double-quoted. The whole command pipeline may be put into one single argument, so in a shell the following is ok:**

**\_\_piper 'echo "Hello    lots of space" \| sed "s/ts of/st in/g"'**

**Double quotes, the pipe symbol and the backslash itself may be escaped by a preceding backslash "** **The advantage using this program instead of a shell with the -c option should be a much faster startup of the whole pipeline.**  **This is useful in the process- and uncrosses commands of the client side of afbackup.**
