Just like I last posted the below script can be used to remove blank spaces from file names.
#!/bin/sh
find . -name "* *"|while read file
do
target=`echo "$file"|tr -s ' ' '_'`
mv "$file" "$target"
done
Shell provides easy way of renaming multiple files.
Eg: your directory has ’01 – Song1.mp3′, ’02 – Song2.mp3′, ’03 – Song3.mp3′ and you want to rename them to .txt. use the following commane.
$rename mp3 txt *.mp3
The above command renames .mp3 files to .txt.
An alternate script solution from here
#!/bin/sh
ls *.mp3|while read file
do
target=`echo $file|cut -d . -f 1`
#mv "$file" "$target.txt"
echo "$target.txt"
done
First test the above script by seeing the echo "$target.txt" output then uncomment the line above it and comment this line.

Postgresql
If you want to allow other(s) network system to access your
database, you need to make changes in two files : postgresql.conf and
pg_hba.conf.
in postgresql.conf file you need to specify IP address(es) to listen on,
with comma seperated. OR ‘*’ for ALL.
listen_addresses = ‘*’
And in pg_hba.conf you need to add the following line at end :
host all all 192.168.185.1/8 trust
