Code:
ar t file.ipk
ar x file.ipkrespectively. Nowadays ipk packages are managed by opkg.
Actually, although based on deb file format the outer container is not ar (like deb) but a gzipped tar, e.g. inspect the following ipkg-opt_0.99.163-10_arm.ipk.

So to extract the contents you would actually do the following:

Code:
tar xf filename.ipkTo the OP, installing it is another matter and would only be appropriate if you use a system that actually uses .ipk files. What are you actually trying to install, what are you trying to achieve by doing this and what is your distro?

Hi

i m working om IoT board and for that i m using openwrt. i need to install packages for that and i get to know that to install packages in openwrt we need opkg. i m very new in this technology so i dont know anything. i installed opkg and trying to install packages but its giving following error
