我无法确定如何在BusyBox容器中打印(unix工具)版本:
$ docker run -it quay.io/quay/busybox:latest
$ awk --version
awk: unrecognized option `--version'
BusyBox v1.32.0 (2020-08-31 17:40:13 UTC) multi-call binary.
Usage: awk [OPTIONS] [AWK_PROGRAM] [FILE]...
-v VAR=VAL Set variable
-F SEP Use SEP as field separator
-f FILE Read program from FILE
-e AWK_PROGRAM
$ cut --version
cut: unrecognized option `--version'
BusyBox v1.32.0 (2020-08-31 17:40:13 UTC) multi-call binary.
Usage: cut [OPTIONS] [FILE]...
Print selected fields from each input FILE to stdout
-b LIST Output only bytes from LIST
-c LIST Output only characters from LIST
-d CHAR Use CHAR instead of tab as the field delimiter
-s Output only the lines containing delimiter
-f N Print only these fields
-n Ignored
有什么建议吗?许多热的容器都建在BusyBox的顶部,我最好能做到这一点。
谢谢
