# sed 
Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

  -n, --quiet, --silent
                 suppress automatic printing of pattern space
  -e script, --expression=script
                 add the script to the commands to be executed
  -f script-file, --file=script-file
                 add the contents of script-file to the commands to be executed
  --follow-symlinks
                 follow symlinks when processing in place
  -i[SUFFIX], --in-place[=SUFFIX]
                 edit files in place (makes backup if SUFFIX supplied)
  -c, --copy
                 use copy instead of rename when shuffling files in -i mode
  -b, --binary
                 does nothing; for compatibility with WIN32/CYGWIN/MSDOS/EMX (
                 open files in binary mode (CR+LFs are not treated specially))
  -l N, --line-length=N
                 specify the desired line-wrap length for the `l' command
  --posix
                 disable all GNU extensions.
  -r, --regexp-extended
                 use extended regular expressions in the script.
  -s, --separate
                 consider files as separate rather than as a single continuous
                 long stream.
  -u, --unbuffered
                 load minimal amounts of data from the input files and flush
                 the output buffers more often
  -z, --null-data
                 separate lines by NUL characters
  --help
                 display this help and exit
  --version
                 output version information and exit

If no -e, --expression, -f, or --file option is given, then the first
non-option argument is taken as the sed script to interpret.  All
remaining arguments are names of input files; if no input files are
specified, then the standard input is read.

Had the same problem with a different use-case:

k3d cluster create test --kubeconfig-update-default=0 --image rancher/k3s:v1.27.15-k3s1 --wait --timeout=240s --no-lb --network test

This works with k3d 5.6.0 and 1.27.1<=k3s<=1.27.15 but fails with the image is k3s:v1.27.16-k3s1 with the same error:

With v5.6.0 k3d version outputs ... k3s version v1.27.4-k3s1 (default) so I tried to run with newer version. The same problem happens with all released k3d versions upto and including 5.7.2. Although k3d version for v5.7.2 outputs 

k3d version v5.7.2
k3s version v1.29.6-k3s2 (default)

It fails to start a cluster with k3s v1.27.16+k3s1 although versions more 'recent' in semver terms work fine.

This problem is fixed in v5.7.3

The reason appears to be this change that adapts to the change in xargs version shipped in k3s. This can be misleading for users since unsupported versions can only be identified by release date. This issue is probably caused by k3s but I think this project needs to be document, for each minor version the highest patch version supported since not all are.
