发现Ubuntu22.04的桌面版和服务器版的awk是不同的实现
Ubuntu22.04Server服务器版默认用的是gawk , 也带mawk
Ubuntu22.04Desktop桌面版用的是mawk 不带gawk
Server版既有gawk,又有mawk, 默认gawk
root@us224-1:~# mawk
Usage: mawk [Options] [Program] [file ...]
Program:
The -f option value is the name of a file containing program text.
If no -f option is given, a "--" ends option processing; the following
parameters are the program text.
Options:
-f program-file Program text is read from file instead of from the
command-line. Multiple -f options are accepted.
-F value sets the field separator, FS, to value.
-v var=value assigns value to program variable var.
-- unambiguous end of options.
Implementation-specific options are prefixed with "-W". They can be
abbreviated:
-W version show version information and exit.
-W dump show assembler-like listing of program and exit.
-W help show this message and exit.
-W interactive set unbuffered output, line-buffered input.
-W exec file use file as program as well as last option.
-W random=number set initial random seed.
-W sprintf=number adjust size of sprintf buffer.
-W posix_space do not consider "\n" a space.
-W usage show this message and exit.
root@us224-1:~# gawk
Usage: gawk [POSIX or GNU style options] -f progfile [--] file ...

Short options: GNU long options: (extensions)
-b --characters-as-bytes
-c --traditional

-E file --exec=file
-g --gen-pot
-h --help
-i includefile --include=includefile
-l library --load=library

-n --non-decimal-data
-o[file] --pretty-print[=file]
-O --optimize
-p[file] --profile[=file]
-P --posix

-s --no-optimize
-S --sandbox
-t --lint-old
-V --version
To report bugs, see node `Bugs' in `gawk.info'
which is section `Reporting Problems and Bugs' in the
printed version. This same information may be found at
https://www.gnu.org/software/gawk/manual/html_node/Bugs.html.
PLEASE do NOT try to report bugs by posting in comp.lang.awk,
or by using a web forum such as Stack Overflow.
gawk is a pattern scanning and processing language.
By default it reads standard input and writes standard output.
Examples:
gawk '{ sum += $1 }; END { print sum }' file
gawk -F: '{ print $1 }' /etc/passwd
