I have written the script, which unzips a zip file (passed as argument to the bash), loops through directory and files, then perform different actions based on directory or file. It is working fine.However I would like to know some things:Is it possible to do this without the unzip command? I somehow feel like that step can be avoided and we can directly use the zip file to perform the task.I have used three temporary files/directories(tmp.txt - to store the directory and file lines, out.xml - for the curl command, DIREC - for finding the files and directories). I have removed those three files at the end of the script. Is there a way to optimize this? may be using variables instead of files.Here is the bash script, with comments:#!/bin/bash#The below line unzips the zip file as passed as argumentunzip $1length=${#1}const=4count=$((length-const))DIREC=$(echo $1 | cut -b 1-$count)OUTPUTFIL=out.xml#The below line will find the directory, which was created by the unzip command. Creation of tmp.txt here.find $DIREC -exec echo {} \; >tmp.txtexec<tmp.txt   while read line   doif [ -d ${line} ] ; then    echo $line is a directory;else    if [ -f ${line} ]; thenBASE=$(base64 $line);        echo ${line} is a file;{    echo <inpu>${BASE}</inpu>} > ${OUTPUTFIL}curl -u admin:secret --data-binary @out.xml http://dp1-l2.com; echo    else        echo ${line} is not valid;        exit 1    fifi   donerm -f tmp.txtrm -rf $DIRECrm -f out.xml
