Variables passed through to Scripts [SOLVED]

Recommended Posts

I have a situation whereby i call a script within a script, within the current shell.. i.e:

 

 

SCRIPT1.sh:

 

. ./path/to/script/script2.sh

 

SCRIPT1.sh is one of many script we run and can do a range of things, script2.sh is set up to return three variables from it USERNAME, PASSWORD and DATABASE. The USERNAME and PASSWORD generated in script 2 depends on username of the user running the script OR a passed variable (i.e. $1).

 

All of the above works so:

 

SCRIPT1.sh could call script2.sh as follows:

 

. ./path/to/script/script2.sh DIFFUSER

 

The script2 is run within script1's CURRENT shell as to allow SCRIPT1 access to the values passed back.

 

The problem, if i have the following script1:

 

SCRIPT1.sh

#---

echo $1

echo $2

 

. ./path/to/script/script2.sh DIFFUSER

 

echo $USERNAME

echo $PASSWORD

echo $DATABASE

 

echo $1

echo $2

#---

 

run like:

SCRIPT1.sh VALUE1 VALUE2

 

It all works as expected BUT on the second echo of $1 in SCRIPT1 the value is altered to DIFFUSER from VALUE1.

 

This is not acceptable.

 

Now the constraints i have is:

 

. ./path/to/script/script2.sh

 

has to be able to run without requiring any parameters (default)

 

It has to run with a parameter passed to it to allow it to pick up new usernames, passwords, DB based on the passed variable.

 

I have got a workaround to this by doing the following:

 

SCRIPT1.sh

#---

echo $1

echo $2

 

. ./path/to/script/script2.sh ${1:-1} ${2:-2} DIFFUSER

 

echo $USERNAME

echo $PASSWORD

echo $DATABASE

 

echo $1

echo $2

#---

 

But if the SCRIPT1 variants ever have more than 2 parameters passed to them then script2 will mess things up.

 

I can not alter the way the script2 is called, i can alter script2 though..

 

Ideas (script 2 does some processing then exports the variables, and has to be run as ". ./path/script2.sh" i.e. in the current shell.

 

Ideas?

sorted the problem.. used the following:

 

---script2.sh---
function checkparam {

PARMS=$*

server=`echo $PARMS | awk ' { print $NF } '`
checkparm=`echo $server | awk -F_ ' { print ( $1 ) } ' `
case ${checkparm} in
  "CHECKPARAM")  export var_server=${server};;
                 *)  export var_server=${UKSSP}
esac


}

checkparam $*

echo "var_server = $var_server"

 

when we pass a value to the script2.sh now we use . ./path/script2.sh $* PARAM
