Shell Programming and Scripting

Yep, a cd in $ORACLE_HOME/owb/bin/unix/OMBPlus.sh
does not have an affect on the calling script (parent process),
unless it is included with

Code:

source $ORACLE_HOME/owb/bin/unix/OMBPlus.sh

or

Code:

. $ORACLE_HOME/owb/bin/unix/OMBPlus.sh

Hello MaidinGermany,
I re-write my code as below, please advise if this is ok. Thanks.

Code:

#!/bin/sh -fb
cd $ORACLE_HOME/owb/bin/unix/
./OMBPlus.sh
source /app/mes_dwh/test/$plugin/$plugin/$plugin/$plugin/omb/delete_all.tcl

Yes try it.
And also

Code:

#!/bin/sh -f
. $ORACLE_HOME/owb/bin/unix/OMBPlus.sh
. /app/mes_dwh/test/$plugin/$plugin/$plugin/$plugin/omb/delete_all.tcl

sh does not need a -f like sed and awk, and in fact it affects globbing, -b is only effective interactively, when there is job control, but sometimes we put in a -x for debug to see what it is doing.


-f Disable pathname expansion.


-b Report the status of terminated background jobs immediately, rather than before the next primary prompt. This is effective only when job control is enabled.

The effect of first line $!xxxx is a new command: xxxx "$0" "$@"

The man page for sed and awk says to run a script file use -f, but for sh it says just put it on the command line.
