# dshbak(1)

format output from pdsh command

## NAME

dshbak - format output from pdsh command

## SYNOPSIS

**dshbak** \[*OPTION*\]..

## DESCRIPTION

The **dshbak** program formats **pdsh** pdsh output for humans. Output from each node is consolidated, the leading "*node:*" is stripped, and a header block with the node name is added. If the *-c* option is specified, nodes with identical output are not displayed twice; instead, the header will contain a list of nodes. The list of nodes is further compressed into node ranges if the node names have a numeric suffix.

## OPTIONS

- **-h**

  Display a summary of command line options.

- **-c**

  Do not display identical output from nodes twice. Instead, print the list of nodes with matching output in the header block.

- **-d** *DIR*

  Write consolidated node output to separate files in output directory *DIR*. Any existing files will be overwritten.

- **-f**

  With *-d*, force creation of specified *DIR*.
