I have a tab delimited text file where the first column can take on three different values : 100, 150, 250. I want to extract all the rows where the first column is 100 and put them into a separate text file and so on. This is what my text file looks like now:

I have a space delimited text file. I want to extract rows where the third column has 0 as a value and write those rows into a new space delimited text file. How do I go about doing that? Thanks! (2 Replies)
I would like to extract the last column of a text file but different rows of the text file have different numbers of columns. How do I go about doing that? Thanks! (1 Reply)
Hi,
I have a tab delimited text file with multiple columns. The second and third columns include numbers that have not been sorted. I want to extract rows where the second column includes a value between -0.01 and 0.01 (including both numbers) and the first third column includes a value between... (1 Reply)
Hello, I have a file with nearly 57K lines. I want to filter the lines based on the range of values in a column. For e.g. print lines whose 3rd filed is >=0.02.

idmap_tdb - Samba's idmap_tdb Backend for Winbind
DESCRIPTION
The idmap_tdb plugin is the default backend used by winbindd for storing SID/uid/gid mapping tables.
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_tdb backend itself or by any other allocating backend like
idmap_ldap 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 tdb 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
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.
EXAMPLES
This example shows how tdb is used as a the default idmap backend. It configures the idmap range through the global options for all domains
encountered. This same range is used for uid/gid allocation.
[global]
# "idmap backend = tdb" is redundant here since it is the default
idmap backend = tdb
idmap uid = 1000000-2000000
idmap gid = 1000000-2000000
This (rather theoretical) example shows how tdb can be used as the allocating backend while ldap is the default backend used to store the
mappings. It adds an explicit configuration for some domain DOM1, that uses the tdb idmap backend. Note that the same range as the default
uid/gid range is used, since the allocator has to serve both the default backend and the explicitly configured domain DOM1.
[global]
idmap backend = ldap
idmap uid = 1000000-2000000
idmap gid = 1000000-2000000
# use a different uid/gid allocator:
idmap alloc backend = tdb
idmap config DOM1 : backend = tdb
idmap config DOM1 : range = 1000000-2000000
