Using Output from one command as input to another
This site has been very helpful thus far.. I thank you all in advance for sharing the knowledge. Let me get to it.
I am trying to write a very small script to take away from the boredom of doing the same thing over and over.
Everynow and again I have to get the hex value of a file using a d2h. I wrote a one line wrapper around it so that I would have to create symlinks or change directories and I needed to brush up anyway.
#!/bin/bash
/xxx/xxxx/bin/d2h $1
Automatically the output is sent to my screen. How can I change that so that I can just pull that output and add this line into my script so that I can kill 2 birds with one stone??:
cd /xxx/xxxx/data
find . -name \*$OUTPUTFROMLAST COMMAND\* -ls
Please excuse my lack of challenge to some of you, I have been out of the industry for 3 years... I am trying to get this stuff to come back to me.
THanks in advance.

NAME
idmap_tdb2 - Samba's idmap_tdb2 Backend for Winbind
DESCRIPTION
The idmap_tdb2 plugin is a substitute for the default idmap_tdb backend used by winbindd for storing SID/uid/gid mapping tables in
clustered environments with Samba and CTDB.
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.
IDMAP OPTIONS
range = low - high
Defines the available matching uid and gid range for which the backend is authoritative.
script
This option can be used to configure an external program for performing id mappings instead of using the tdb counter. The mappings are
then stored int tdb2 idmap database. For details see the section on IDMAP SCRIPT below.
IDMAP SCRIPT
The tdb2 idmap backend supports an external program for performing id mappings through the smb.conf option idmap config * : script or its
deprecated legacy form idmap : script.
The mappings obtained by the script are then stored in the idmap tdb2 database instead of mappings created by the incrementing id counters.
It is therefore important that the script covers the complete range of SIDs that can be passed in for SID to Unix ID mapping, since
otherwise SIDs unmapped by the script might get mapped to IDs that had previously been mapped by the script.
The script should accept the following command line options.
SIDTOID S-1-xxxx
IDTOSID UID xxxx
IDTOSID GID xxxx
And it should return one of the following responses as a single line of text.
UID:yyyy
GID:yyyy
SID:yyyy
ERR:yyyy
EXAMPLES
This example shows how tdb2 is used as a the default idmap backend.
[global]
idmap config * : backend = tdb2
idmap config * : range = 1000000-2000000
This example shows how tdb2 is used as a the default idmap backend using an external program via the script parameter:
[global]
idmap config * : backend = tdb2
idmap config * : range = 1000000-2000000
idmap config * : script = /usr/local/samba/bin/idmap_script.sh
