Coreutils cksum missing.

nix666

Hi All,
I want to use the cksum command which is part of coreutils, or rather should be.
I have coreutils installed on my Omega2 + , but the cksum command is not available.
How do I add/compile coreutils to include this command or make it available ?

Any advice will be much appreciated.

Thank you.

@nix666 You can build coreutils with cksum included using the build system, it seems it is not inlcued in the standard OpenWrt build of coreutils.

The docs of how to set up a build system are here:

@nix666 You didn't tell us what firmware are you using - as usual

For example:

# Omega2+ with FW v0.3.2 b234

root@Omega-99A5:/# opkg update
 ...
root@Omega-99A5:/# opkg install coreutils-cksum
Installing coreutils-cksum (8.23-4) to root...
Downloading http://repo.onioniot.com/omega2/packages/packages/coreutils-cksum_8.23-4_mipsel_24kc.ipk
Configuring coreutils-cksum.

root@Omega-99A5:/# cksum --help
Usage: cksum [FILE]...
  or:  cksum [OPTION]
Print CRC checksum and byte counts of each FILE.

      --help     display this help and exit
      --version  output version information and exit

Good luck.

Thanks for the reply, both of you. My apologies for not mentioning my firmware version. I managed to download cksum on its own from here : https://downloads.openwrt.org/releases/17.01.7/packages/mipsel_24kc/packages/
Package name is coreutils-cksum_8.23-3_mipsel_24kc.ipk. Installed it via opkg.
