how to share any folder of your pc over ftp or vsftp

How to share any folder of your PC over ftp or vs-ftp

say i need to  share /media/usb5/ftp folder over ftp ...

Follow the following steps:

As we know The default location on ftp is /home/user/.


* mkdir /media/usb5/ftp

now see when u do "ftp ip-of-ur-pc" from a another pc , u will have /home/user/ as default location .  so we will go  as follow.

* mount --bind /media/usb5/ftp /home/user/

and

* service vsftpd restart

dats all

put all the file u want to share over ftp on /media/usb5/ftp folder with proper
permission .

If u want to default location back ,

* umount /media/usb5/ftp

and now you can edit the /etc/fstab file with vi editor .

script for interview perpose

Write a bash​ shell​ or perl script which does the following:

 - accepts a syslog file path, comma seperated list of service names and another argument which is a string (​this is an optional argument)

 - prints the count of logs of each service name on a separate line

 - If the optional string argument is provided, then searches for it in the logs of the provided service names and prints its count ​on a separate line.

 - prints usage if it is incorrect

 This was interview question for me .  Look how i have given the solution after 3 attempt :)
