Hi,
on AIX 6.1

I have a shell script that calls another shell which have some parameters. Say like the following :

##This is main script############
myparameters.sh
command1
command2
.....
....

And here myparameteres.sh :

export ORACLE_SID=MYDB
export mydir='/appli/oracle/BACKUP/RMAN/INCR/$ORACLE_SID'
export user=rmanuser

The problem is that after comming back to the main script the parameteres have lost their values :

echo $ORACLE_SID
ANOTHERDB

How can I resolve this ??
Thank you.

In sh/ksh/bash... you 'source' your parameter file like so:

##This is main script############
. myparameters.sh
command1
command2
.....
....

realy thank you.

I call myparameters.sh script :
. myparameters.sh abcd

And then in myparameters.sh, I set a parameter like this :

export mydir='/appli/oracle/BACKUP/RMAN/$1/$ORACLE_SID'

But the result is :

echo $mydir

/appli/oracle/BACKUP/RMAN/$1/$ORACLE_SID

ORACLE_SID is set (exported) in main script.

thanks for help.

export mydir="/appli/oracle/BACKUP/RMAN/$1/$ORACLE_SID"

thank you.
It's ok.

Isn't $1 just the first parameter? You're not giving it any parameters when you source it, so $1 will be blank at best.

yes, he/she is:

. myparameters.sh abcd
