1. Shell Programming and Scripting
Hi, I'm very new to scripting.
grep $s $filename | awk '{print $2}' | cut -c 1-8
How can I optimize this using a single awk?
I tried:
awk '/$s/ {print $2}' $filename | cut -c 1-8
However didn't work, I think the awk is not recognizing $s and the verbal is something else. (6 Replies)

IDMAP_LDAP(8) System Administration tools IDMAP_LDAP(8)
NAME
idmap_ldap - Samba's idmap_ldap Backend for Winbind
DESCRIPTION
The idmap_ldap plugin provides a means for Winbind to store and retrieve SID/uid/gid mapping tables in an LDAP directory service.
In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new user and group IDs
in order to create new mappings. The allocator can be provided by the idmap_ldap backend itself or by any other allocating backend like
idmap_tdb or idmap_tdb2. This is configured with the parameter idmap alloc backend.
Note that in order for this (or any other allocating) backend to function at all, the default backend needs to be writeable. The ranges
used for uid and gid allocation are the default ranges configured by "idmap uid" and "idmap gid".
Furthermore, since there is only one global allocating backend responsible for all domains using writeable idmap backends, any explicitly
configured domain with idmap backend ldap should have the same range as the default range, since it needs to use the global uid / gid
allocator. See the example below.
IDMAP OPTIONS
ldap_base_dn = DN
Defines the directory base suffix to use when searching for SID/uid/gid mapping entries. If not defined, idmap_ldap will default to
using the "ldap idmap suffix" option from smb.conf.
ldap_user_dn = DN
Defines the user DN to be used for authentication. If absent an anonymous bind will be performed.
ldap_url = ldap://server/
Specifies the LDAP server to use when searching for existing SID/uid/gid map entries. If not defined, idmap_ldap will assume that
ldap://localhost/ should be used.
range = low - high
Defines the available matching uid and gid range for which the backend is authoritative. If the parameter is absent, Winbind fails over
to use the "idmap uid" and "idmap gid" options from smb.conf.
IDMAP ALLOC OPTIONS
ldap_base_dn = DN
Defines the directory base suffix under which new SID/uid/gid mapping entries should be stored. If not defined, idmap_ldap will default
to using the "ldap idmap suffix" option from smb.conf.
ldap_user_dn = DN
Defines the user DN to be used for authentication. If absent an anonymous bind will be performed.
ldap_url = ldap://server/
Specifies the LDAP server to which modify/add/delete requests should be sent. If not defined, idmap_ldap will assume that
ldap://localhost/ should be used.
EXAMPLES
The follow sets of a LDAP configuration which uses two LDAP directories, one for storing the ID mappings and one for retrieving new IDs.
[global]
idmap backend = ldap:ldap://localhost/
idmap uid = 1000000-1999999
idmap gid = 1000000-1999999
idmap alloc backend = ldap
idmap alloc config : ldap_url = ldap://id-master/
idmap alloc config : ldap_base_dn = ou=idmap,dc=example,dc=com
NOTE
In order to use authentication against ldap servers you may need to provide a DN and a password. To avoid exposing the password in plain
text in the configuration file we store it into a security store. The "net idmap " command is used to store a secret for the DN specified
in a specific idmap domain.
