Shell Programming and Scripting

Hi,
I have defined a few parameters in .profile. Here is how it looks like..

export ABC_HOME=/vol.nas/b20/abc/13.0/nm53/abc-13.0
export RFX_TMP=/vol.def/u50/abc/13.0/nm456/abc-13.0/tmp
export SQLPATH=:/dba/sql
export TEST_ABC_INTEGRATION_HOME=/home/txt/lms
export TEST_ABC_CONFIG_FILE=/home/txt/abc/config.xml
ORACLE_HOME=/u00/oracle/product/10.2.0
export ORACLE_HOME

PATH=$ORACLE_HOME/bin:$RFX_TMP:$RFX_HOME/bin:${PATH}

I need to write a shell script that prints few of these variables. Also to print the path some of the configura
This script should be reusable such that when other users log on to
their .profiles, they can also use this to print same variables.

Thanks,
neha

You really should look for a tutorial, have you never echo the PATH variable? Google for "ksh scripting".

echo is fine.. But how can this be made reusable.. So that any user can invoke it from his .profile

Your requirements are too fuzzy to really understand where you want to go with this. Is there a particular subset of variables, or should users be able to pick and choose which ones they want to print? If the latter case, why not just teach them the basics of the shell so they can inspect the variables at will?

Assuming there is a fixed set of variables you want to print, how about

Code:

#!/bin/sh
set | egrep '^(ABC_HOME|SQLPATH|ORACLE_HOME)='

You could save this in /usr/local/bin/printvars and chmod a+x, assuming you don't already have a command by that name, and assuming your users are set up with /usr/local/bin in their PATH.
