scripts adminBuildDomain and crstEnv are in the same directory. from this directory only we run all the scripts.
adminBuildDomain calls crstEnv
Code in adminBuildDomain is: . ${0%${0##*/}}crstEnv
${0%${0##*/}}crstEnv returns crstEnv value
since the directory path where we run the scripts is same as the directory where the scripts are present, we can use . ./crstEnv instead of . ${0%${0##*/}}crstEnv
i really dont understand the importance of ". ${0%${0##*/}}crstEnv" in this case. i dont understand why ". ${0%${0##*/}}crstEnv" is used instead of ". ./crstEnv"

Hello everyone,
I'm looking for the meaning of this expression, as I don't understand it quite clearly : $1^
What do you think it could be?
I thought either:

- turn line around : word becomes drow

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
working directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop
commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com-
mand.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
