Free space on /

I'm facing very low disk space in the system under / (root).I frequently clean using the below tips , but still not enough.
################# Disk Cleaning Tips ####################
du -khs /var/* | sort -nr | head # top 10 var files
du -khs /var/cache/* | sort -nr | head # top 10 cache files
sudo apt-get clean # clean downloaded packages
sudo apt-get autoclean # remove stored archives in cache
sudo apt-get autoremove # auto remove unnecessary packages
find /var/log/* -maxdepth 1 -type f -size +1M -exec ls -lhS {} \; | awk '{ print $5,"",$9 }'|sort -nr | head -10 # list top 10 log files
Here's my disk usage:
kesavan@kesavan-Ideapad-Z460:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda7 3.8G 3.6G 52M 99% /
udev 1.5G 4.0K 1.5G 1% /dev
tmpfs 578M 1.1M 577M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 1.5G 344K 1.5G 1% /run/shm
/dev/sda9 7.5G 6.4G 1.1G 86% /home
/dev/sda1 344G 324G 2.0G 100% /media/DATA

/dev/sda6 82G 71G 6.7G 92% /media/bfbc93c8-62db-4b3e-9cce-a01860d098f2
Is there something I can pull out from /usr? Seems nearly 1.3GB on /usr/share. Can I purge something out of that?
kesavan@kesavan-Ideapad-Z460:~$ sudo du -k --max-depth=1 /usr/* | sort -nr| cut -f2 | xargs -d '\n' du -khs
1.3G /usr/lib
998M /usr/share
193M /usr/src
121M /usr/bin
26M /usr/sbin
11M /usr/include
800K /usr/games
164K /usr/local
Any other tips to free more space?

If I was you, I'd first go get an external disk and make a backup of the whole thing. I never heard of a guy who regretted he had backups! Of course, you already might have a backup.
After that, I'd shrink another ext4 partition with more free space and then grow /. You can do so using e.g.
Older kernels (images and, maybe, headers) are not automatically removed and take quite some space. You can remove them from the package manager (search "linux-").
But 3.8 GB is not much and the long-term solution would be to extend the / partition from a Live CD (Trisquel's, for instance, has GParted). However, if you kept Trisquel's defaults, your /home is an XFS filesystem... and XFS filesystems cannot be shrunk. So you would need to backup the content of /home, remove its partition, extend that of / and repopulate /home from the backup.

apt-get doesn't incredibly enough have a man page but
$ apt-get --help|grep -E 'clean|autoremove'
autoremove - Remove automatically all unused packages
clean - Erase downloaded archive files
autoclean - Erase old downloaded archive files
(if this was a small disk, then also localepurge might come handy, read its caveats though)
Note, though, that this doesn't clean up old kernel images. Those need to be removed manually.
Everyone, Thanks for the suggestions.As long term pla, I wish to extend the size of the / prtition.
Let me try with GParted and come back with the outcome.
