Hi everyone,

i'm in the process of migrating our cron-container to alpine. We've been using a little helper script to measure some stats for the executed scripts much like mk-job from check_mk. This tool uses the 'time'-command (not the alias or similar) to output stats like this:

...
/usr/bin/time -o "$OUTPUT_PATH/$IDENT.running" --append \
              -f "exit_code %x
              real_time %E
              user_time %U
              system_time %S
              reads %I
              writes %O
              max_res_kbytes %M
              avg_mem_kbytes %K
              invol_context_switches %c
              vol_context_switches %w" "$@"
...

Does something similar exist in alpine?

greetings,

There doesn't seem to be a package in the repositories:

https://pkgs.alpinelinux.org/contents?file=time&path=&name=util-linux&branch=edge&repo=main&arch=armhf

However, Arch Linux has packaged it, here is the PKGBUILD & patches:

https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/time

Alpine's APKBUILDs are sufficiently similar that Arch's files can be used as a "cheat sheet" and template.

Official guide here:

https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package

Once the APKBUILD is written, use `abuild -r` to make the package and `apk add ~/packages/$dir/time*.apk` (where $dir is the build directory) to install it.

If it all works you could even submit the package to Alpine's testing repositories so everybody can use it.
