Shall i try repartitioning my root through boot disk or there is any

since all the applications are stored in my home partition

This is a big reason to have more than /, swap, and /home.

Boot up in single-user. If there isn't enough disk space for that, boot
up in init=/bin/sh and mount your filesystem read-only (so that it
doesn't get atimes updated or any other attempts to write to a full
device). If you can, activate swap and get /tmp on tmpfs to give you
something to shuffle with.

Since its all one big fs, df won't help much but run it anyway to see
how full things are after this fresh reboot.

Since /usr can be mounted ro, its only supposed to change when you
add/remove/update packages, so there should be no surprises under /usr.

Check /var. Especially, /var/tmp, /var/cache. The FHS says that files
in /var/cache "is locally generated as a result of time-consuming I/O or
calculation. The application must be able to regenerate or restore the
data. Unlike /var/spool, the cached files can be deleted without data
loss.

Then check in /home. If you find any really big files, see if you can
gzip them up to save space. If there are big directories, perhaps
tarball them.

Once you get enough room to work, you can reboot into single-user mode
and run your normal backup routine. Then decide where to prune to get a
sane system again.

Good luck.

Doug.
