Bash script to clean movies name


The issue when you download movies online, is that most of the time the file name is going to be complete trash , filled with useless info like the team that made the rip or the website from where the movie was downloaded.
This is very annoying when you sort by name and the website made the idiotic decision to put their name in front of the actual film name.

for example here a typical movie name
[ Torrent9.info ] Dont.Think.Twice.2016.FRENCH.WEBRip.XviD-NEWCiNE.avi
the actual useful data that i wish to keep is Dont.Think.Twice.2016.avi

for this purpose i’ve developped a small bash script that will list all the files in a chosen directory then , if necessary , will rename the file.

this is not a very efficient script
but it’s fulfill it’s purpose and very rarely encounter a filename that he is unable to clean.

BASH:check if a number is even or odd


In a bash script you might need to check if a var is even or odd , 

in my case im going to use a if to make that check

You can use this simple code to make that check and display the result.

the result will be : 

BASH : IP validation 

if you have a list of ip to validate ,
you can use this little bash script ,
this will open your IP list ,
then test if all the 4 numbers that make a standard IP.are beeten 0 and 255

if the ip is valid then the script will return valid , else it will return : not valid

after execution , you will get the following result :

Bash : Delete some characters from a file with TR

in this little example of usage of the command tr
we want to clean a file so the values contained in it can be used
Example File

In my example i wish to only keep the value and deleting the character < and >

the tr command used with the -d (delete) option will allow you to delete the list of characters contained between the quotes.

You will obtain the following result

BASH : Delete the last X chars from a string

sed delete last x chars

When you scrap data in HTML , it’s common , depending on the quality of you regex to end up with a string with some useless character at the end (Or the Beginning),

If you string looks like that :

My useful data</a> <

You can use the command head to drop the X last character of your string ,
So in my Case , to Keep only the string My useful data and drop the </a> <

I’m going to pipe my string to

This will delete the last 6 chars of my string , giving the data that i need later in my script

but in some implementation of the head command this will not work ,

you can use an alternative with sed

This will delete the last 4 characters of your line ,  or alternatively
