Invoking shell script with perl command.
Hi All, I am using the following command to invoke the shell script from a perl command. Code:
perl -i.bak -pe'BEGIN { $cmd = "/opt/coreservices/tomcat-5.5.9/bin/digest.sh -a sha"; }
s/(password=")([^"]*)/
$1.`$cmd $2|cut -d: -f2|tr -d "\n"`
/e
' $CATALINA_HOME/conf/tomcat-users.xml
I need to put in $CATALINA_HOME where I have /opt/coreservices/tomcat-5.5.9 , so the statement should be something like Code:
perl -i.bak -pe'BEGIN { $cmd = "$CATALINA_HOME/bin/digest.sh -a sha"; }
s/(password=")([^"]*)/
$1.`$cmd $2|cut -d: -f2|tr -d "\n"`
/e
' $CATALINA_HOME/conf/tomcat-users.xml
Now since perl does not understand the shell variables, I did the following, but it is not working. Code:
typeset -x MY_VARIABLE=$CATALINA_HOME
perl -i.bak -pe'BEGIN { $cmd = "$MY_VARIABLE"/bin/digest.sh -a; }
s/(password=")([^"]*)/
$1.`$cmd $2|cut -d: -f2|tr -d "\n"`
/e
' $CATALINA_HOME/conf/tomcat-users.xml
Can anyone please help! |

Hi ! You can get environment variable by through %ENV hash. In your case: Code:
perl -i.bak -pe'BEGIN { $cmd = $ENV{CATALINA_HOME}/bin/digest.sh -a; }
s/(password=")([^"]*)/
$1.`$cmd $2|cut -d: -f2|tr -d "\n"`
/e
' $CATALINA_HOME/conf/tomcat-users.xml
