Programming Forums - Bash Script Deletion help

I want to change some features on a particular code. This code must delete files that haven't been used in the directory.

Here's my code that I saw an example of:

#!/bin/sh



#< Delete an entry from the address book



_ADDRESS_BOOK=$HOME/a_book/a_book

_TEMP_FILE=$HOME/tmp/a_book.tmp.$$

_ENTIRE_FILE=$HOME/tmp/a_full.tmp.$$



# As a : appears in every line, this has the effect

# of numbering the lines in the fashion we want.

grep -in ":" ${_ADDRESS_BOOK} > ${_ENTIRE_FILE}



echo "Enter a searchterm for your deletion:"

read _SEARCHTERM



grep -in "${_SEARCHTERM}" ${_ADDRESS_BOOK} > ${_TEMP_FILE}



_count=$(wc -l < ${_TEMP_FILE})

echo "${_count} match(es) found!"



while read line

do

  _record_number=$(echo $line | awk -F: '{print $1}')

  _records="${_records} ${_record_number}"

done < ${_TEMP_FILE}



echo ""



for record in ${_records}

do

   _current_rec=$(grep "^${record}:" ${_TEMP_FILE})

   _firstname=$(echo ${_current_rec} | awk -F: '{print $2}')

   _surname=$(echo ${_current_rec} | awk -F: '{print $3}')

   _address1=$(echo ${_current_rec} | awk -F: '{print $4}')

   echo "===================================================="

   echo "${_firstname} ${_surname} of"

   echo "${_address1}"

   echo "DO YOU WANT TO DELETE THIS RECORD? [y/n]"

   read response

   case $response in

     [yY]|[yY][eE][sS])  

        grep -v "^$record:" ${_ENTIRE_FILE} > ${_ENTIRE_FILE}_v

    cp -f ${_ENTIRE_FILE}_v ${_ENTIRE_FILE}

        cut -d':' -f 2-11 ${_ENTIRE_FILE}_v > ${_ADDRESS_BOOK}

        echo "ENTRY DELETED!"

        ;;

     *) ;;

   esac

done



rm -rf ${_TEMP_FILE}

rm -rf ${_ENTIRE_FILE}

rm -rf ${_ENTIRE_FILE}_v

Here's another example:



#!/bin/bash

#< Script to remove old quarantine and virus mails, plus cocoon logs from web/mail servers



ECHO="/bin/echo"

FIND="/usr/bin/find"

RM="/bin/rm"

SLEEP="/usr/bin/sleep"

TR="/usr/bin/tr"

XARGS="/usr/bin/xargs"



TARGET[0]="/www/webapps/cocoon/WEB-INF/logs"

TARGET[1]="/var/amavis/quarantine"

TARGET[2]="/var/amavis/virusmails"



${ECHO} "WARNING: This script will remove all files in the following directories"

${ECHO} "$( ${ECHO} ${TARGET[@]} | ${TR} ' ' '\n' )"

${ECHO} "that haven't been modified for more than 7 days"

${ECHO} "Sleeping for 5 seconds - CTRL-C if you need to!"

${SLEEP} 5



for DIRECTORY in ${TARGET[@]}; do

   ${ECHO} "--> Performing prune in ${DIRECTORY}"

   ${FIND} ${DIRECTORY} -type f -mtime +7 | ${XARGS} ${RM} 2>/dev/null

   ${ECHO} "--> Prune in ${DIRECTORY} complete"

done



exit 0
