How to sort the contents of a file in linux

How to sort the contents of a file in linux

I have a file in a path /tmp which contains some rpm packages. I need to sort the file.

ll /tmp/pckg.txt
sort /tmp/pckg.txt > /tmp/s_pckg.txt
A new file /tmp/s_pckg.txt will be created and the contents in that file will be in sorted order.

sort -r /tmp/pckg.txt > /tmp/s_pckg.txt
Reverse sorted.

sort -nk2 /tmp/s_pckg.txt
On the basis of second column it will sort.
