uncomment or comment one specific line in a config file
Hello.

I want comment or uncomment a ligne in a config file.

The file name : /etc/samba/smb.conf

Normaly the ligne is uncomment :
so the line begin with a tab character
followed by passdb backend =
\tpassdb backend =

In that case I should comment this line and then the line :
begin with #
followed by a tab character \t
followed by passdb backend =
#\tpassdb backend =
When I have finish my test then I want to uncomment this line which return in its initial state.
\tpassdb backend =
This line should be in any position in the file.

#!/usr/bin/sh
#
CMD="$1"

FLAG1="# passdb backend ="
FLAG2=" passdb backend ="
F_NAME="/etc/samba/smb.conf"


case "$CMD" in
"uncmt")
sed search "$FLAG1" replace by "$FLAG2" in file $F_NAME
exit
;;
"cmt")
sed search "$FLAG2" replace by "$FLAG1" in $F_NAME
exit
;;
*)
echo "Usage: comment_uncomment_smb-conf {uncmt|cmt}"
exit
esac

echo "done"

idmap_odsam

IDMAP_ODSAM(8)															    IDMAP_ODSAM(8)

NAME

       idmap_odsam - Open Directory ID mapping backend for winbindd

SYNOPSIS

       The  idmap_odsam plugin is the default backend used by Mac OS X for mapping SIDs and user and group IDs using Open Directory. It implements
       both the "idmap" and "idmap alloc" APIs.

       idmap_odsam should always be used in conjunction with the odsam passdb backend.

IDMAP OPTIONS

       odsam: msglevel = LEVEL
	      LEVEL is the integer log level at which idmap_odsam should emit log messages.  The lower LEVEL is, the more  verbose  the  log  mes-
	      sages.

       odsam: traceall = BOOL
	      If  this	is  true,  idmap_odsam will emit log messages for all Open Directory calls. If it is false (the default), it will only log
	      errors.

IDMAP ALLOC OPTIONS

       The idmap_odsam does not allocate any mappings. On Mac OS X, all SID mappings should be made by modifying the  appropriate  Open  Directory
       record.

EXAMPLES

	    [global]
		idmap domain = default
		idmap config default:default = yes
		idmap config default:backend = odsam

		idmap alloc backend = odsam

		passdb backend = odsam

		odsam: msglevel = 0    # Log at debugging levels
		odsam: traceall = no   # Do not trace Open Directory calls

BUGS

       Please report bugs to Apple.
