perl command issue
Hi,

Please could someone advise on a perl command :

Code:
export ENVPROP="$HOME/cfg/environment.properties.template"
 
export LM_LICENSE=`awk -F= '!/^#/ && /LM_LICENSE/{print $2}' environment.properties`
 
echo $LM_LICENSE
 
$DATA_FILE/licenses/sample.demo.lic
 
perl -i -npe "s#LM_LICENSE.*#LM_LICENSE=$LM_LICENSE#;" $ENVPROP

when I check the $ENVPROP

I only see the value :

Code:
LM_LICENSE=/licenses/sample.demo.lic

( the $DATA_FILE is missing ?? )

Have i entered the perl command wrong ?

thankyou

Use Env module to fetch your environment variables in a Perl script, like so:

Code:
$
$ echo $LM_LICENSE
$DATA_FILE/licenses/sample.demo.lic
$
$
$ echo $ENVPROP
environment.properties.template
$
$
$ cat $ENVPROP
# this is a comment
The license file is LM_LICENSE with a value of blah.
$
$ perl -i -pne 'BEGIN {use Env qw (LM_LICENSE)} s/LM_LICENSE.*/LM_LICENSE=$LM_LICENSE/' $ENVPROP
$
$
$ cat $ENVPROP
# this is a comment
The license file is LM_LICENSE=$DATA_FILE/licenses/sample.demo.lic
$
