ksshell
KSSHELL(1) General Commands Manual KSSHELL(1)NAME
ksshell -- an interactive kickstart shell
SYNOPSIS
ksflatten [-i | --input INFILE] [-o | --output OUTFILE] [-v | --version VERSION]
DESCRIPTION
ksshell is an interactive kickstart shell. It optionally takes an input kickstart file as the basis, allows the user to specify additional
kickstart commands, and then writes out the finished kickstart file to stdout or the given file name. This program supports all the usual
readline niceties including tab completion of kickstart commands and their options, though not the values those options can take.
In addition to understanding all the kickstart commands, ksshell has some builtin commands of its own to make working with kickstart files
in the context of a shell easier:
.clear Clear the existing kickstart data, including any from INFILE. This essentially starts you over from a blank state.
.quit Quit the interactive shell, either saving to the file given by OUTFILE or printing to stdout if none was given.
.show Print the current kickstart file state.
EXIT STATUS
ksflatten returns 0 on success, and 1 if VERSION is incorrect. If INFILE does not exist, a warning will be printed but the user will still
be dumped to the interactive shell.
OPTIONS -i, --input INFILE
The name of the input kickstart file.
-o, --output OUTFILE
Write the flattened kickstart file to OUTFILE, or stdout if no filename is given.
-v, --version VERSION
Use this version of kickstart syntax when processing the file, or the latest if no version is given.
