Error Output into a Variable
i was wondering is there anyway to take the output of a command and put it into a variable??
what i need to to is only take a certain part of the output that lies between <"data needed ">

You can use var=$(...) to put the output of a (series of) command(s) into a variable.

but is there a way that to make it run its self in a script.. this is the command i am issuing "ldapsearch -x '(dn:=dc)' dc|grep dc="

and the output is "# base <dc=james,dc=morey,dc=home,dc=com> (default) with scope subtree"

now i want to make the "dc=james,dc=morey,dc=home,dc=com" into a variable but just that not the other stuff.

Try:
Code:
var=$(ldapsearch -x '(dn:=dc)' dc|grep dc= | awk -F'[<>]' '{print $2}')

or
Code:
var=$(ldapsearch -x '(dn:=dc)' dc | awk -F'[<>]' '/dc=/{print $2}')

i have one more question if you can..
how can i make
dc=james,dc=morey,dc=home,dc=com
to be "james.morey.home.com"
in another ldapsearch

Code:
var=$(echo "dc=james,dc=morey,dc=home,dc=com" | sed 's/dc=//g' | sed 's/,/./g')

OR
Code:
var=$(ldapsearch -x '(dn:=dc)' dc|grep dc= | awk -F'[<>]' '{print $2}' | sed 's/dc=//g' | sed 's/,/./g')

Or all in one go:
Code:
var=$(ldapsearch -x '(dn:=dc)' dc | awk -F'[=.,<>]' '/dc=/{print $3"."$5"."$7"."$9}')
