Hello Experts:
While writing a script to help one of the posts on here, I end up writing a wrong one. I am very much eager to know how this can be corrected.
Aim was to not print specified columns - lets say out of 100 fields, need to print all but 5th, 10th, 15th columns.
Someone already... (13 Replies)

ud.conf
UD.CONF(5) File Formats Manual UD.CONF(5)NAME
ud.conf - ud configuration file
SYNOPSIS
/etc/openldap/ud.conf
DESCRIPTION
The ud configuration file is used to set system-wide defaults to be applied when running ud. Note that each user may specify an optional
configuration file, .udrc, in his/her home directory which will be used instead of the system-wide configuration file.
OPTIONS
The different configuration options are:
HOST <name>
Used to specify the name of an LDAP server to which ud should connect. There may be only one entry per config file. The
server's name can be specified as a domain-style name or an IP address.
BASE <base>
Used to specify the search base to use when performing search operations. The base may be changed by those using ud by using the
cb command. There may be only one entry per config file. The base must be specified as a Distinguished Name in LDAP format.
GROUPBASE <base>
Used to specify the base used when creating groups. The base may be changed by those using ud by using the changegroup command.
There may be only one entry per config file. The base must be specified as a Distinguished Name in LDAP format.
SEARCH <algorithm>
Used to specify a search algorithm to use when performing searches. More than one algorithm may be specified, and each is tried
in turn until a suitable response is found.
Each algorithm specifies a filter that should be used when performing a find operation. Filters contain LDAP-style attribute
types (e.g., uid, cn, postalAddress) and operators to test for equality or approximate equality. Prefix operators may also be
used to specify AND, OR and NOT operations (see ldap(3) for more details on the filter format). Algorithms use a compile-time
constant as a separator to use when parsing the input the user has provided. This parsed input can then be referenced similarly
to an awk program using symbols like $1, $2, and $0 for the entire batch of input.
For example, the algoritm cn=$0 causes ud to perform a lookup on the entire string the user has typed, searching for anything
where the commonName exactly matches the whole thing.
Another example, sn~=$NF causes ud to do a search where the last element the user has typed (NF = number of fields and is a spe-
cial "number" that can be used in awk as well as ud) searching for any matches that approximately match Surname.
Search algorithms also support a special feature which allows one to specify the exact number of fields that must be present in
order for the algorithm to be applied. This number must be specified between square brackets.
For example, [1] uid=$1 causes this algorithm to be applied when the number of fields is exactly equal to one. If there is
exactly one field, the token is looked up as a UID.
