Shell script for searching and listing.

[TatuSalin]

As a "newbie" in this scripting world I would like to ask some advices what kind of shell script would perform fastest search files from the system that have some specific extension, such *.jpg or something similar.

How could I give extension as a parameter and then script would take this given extension as parameter and would after that walk through the system and write these listed/ finded files directly to the file like $hostname.$extension.log.

I was wondering something like this.

#!/bin/bash

EXTENSION=$1
HOSTNAME=$HOST
HOMEFOLDER=/home/

echo "Give extension:" + read $1

if [ $1 eq 0 ]
then
echo "extension missing"
else if [$1 eq 1]
then
echo "Starting to find files that have $1 extension"

find / -name $1 > $HOMEFOLDER/$1.log

fi

So Would this do this task and find all given extensions from the system?

Any suggestions?

Thanks.

I'm not a script expert, so though I'm a little puzzled at the variable declarations, I'll leave that alone at this time (maybe someone else can answer that one).

Find looks okay from a compatibility perspective, but if you want it to a) not spit permission errors at you (when run as a user) and b) run much faster, then I suggest instead of using find, you use locate. You'll need to install one of the packages that includes locate as a program. Locate keeps a cache that's updated once a day, so the results are not necessarily accurate if you've made changes since the last update, though you can update the database manually if you need.
