I am trying to change the value of a enviornment variable thru a script and want to pass a parameter on the commande line, If I hard code the value inside the script the script changes the enviornment variable

. mytest

where my test is
MYVAR=$1
export MYVAR


I am un able to pass parameters as follows

. mytest myparameter


Please guide

Thanks

$1 is passed at the command line

. mytest parameter

The parameter will become $1 as my understanding

My need is to change the enviornment variable and for that I am using the dot script method so that the current enviornment is changed and available after the script exits

run it this way :

Code:

. ./mytest parameter

Code:

[ctsgnb@shell ~]$ env | grep MYVAR
[ctsgnb@shell ~]$ cat mytest
MYVAR=$1
export MYVAR
[ctsgnb@shell ~]$ . ./mytest myparam
[ctsgnb@shell ~]$ env | grep MYVAR
MYVAR=myparam
[ctsgnb@shell ~]$

or can alternatly enter the full path of mytest :

Code:

. /full/path/mytest myparameter

without the dot command the vaules of environemnt are not changed. the script creates a sub shell and that is not available back to the parent shell.

I have tried the way you are mentioning.

Does not Work

. mytest hp4345 Command line

here is the code for mytest

#!/bin/sh
DFPRINTER=$1;export DFPRINTER;

after executing the above the enviornment variable is still same with old value.

this works
. mytest

code#!/bin/sh
DFPRINTER=hp4341;export DFPRINTER;

after executing the above the environment variable DFPRINTER value changes to hp4345


and I want to parametrize the hp4345 part so that I can pass on any desired value

. ./mytest parameter

the parameter is no being passed in to the script

If mytest contains

Code:

#!/bin/sh
DFPRINTER=$1;export DFPRINTER;

where /bin/sh is either the Bourne, Bash or Korn shell and

Code:

. ./mytest hp4345

does not set the environmental variable DFPRINTER to hp4345, then something else is going on.

Please confirm what shell you are using.

Put it in your .profile, or in the script that uses it.
