Sample script to extract virtual host from httpd.conf file of Apache

Home

Requirement:-

A simple script to extract each virtual host defined in an apache configuration file to separate files.

Inputs:-

Apache file absolute path is the only input required for the script.

Outputs:-

Separate files starting with name virtualhost* would be generated in same folder from where script is being executed.

Script:-

#####

#!/bin/bash

# Variable Initialization

FILEPATH=$1

COUNTER=0

#####

if [ $# -eq 1 ]

then

  if [ -f $FILEPATH ]

  then

    # Read Virtualhosts file line by line

    for LINE in $(cat $FILEPATH |grep -v '#' |sed -n '/<VirtualHost/,/<\/VirtualHost/p' |sed '/<\/VirtualHost/ a --------'|tr '\n' '^' |sed 's/\^--------\^/\n/g'| tr ' ' '@' )

    do

      # Extract each virtualhost in seperate file

      echo $LINE| tr '@' ' ' |tr '^' '\n' > virtualhost_$COUNTER.txt

      # Increment Counter for using in next virtualhost out filename

      let COUNTER=$COUNTER+1

    done

  else

    echo "Input file $FILEPATH missing / does not exist"

  fi

else

  echo "Usage: $0 'INPUT VHOST FILE'"

fi

#####

Script is very basic and subject to additional error depending on environment, make sure necessary alternations are made to get it used in any environment.
