[英]How to get awk version on macOS?
I know how to get the version for awk
on Linux: awk -W version
我知道如何在Linux上获取
awk
的版本: awk -W version
This doesn't work, however, on macOS. 但是,这在macOS上不起作用。
I looked around on SO and couldn't find anything. 我四处张望,找不到任何东西。
I also looked in the awk
man page and couldn't find anything: 我还查看了
awk
手册页,但找不到任何内容:
$ man awk | grep version
conversion format used when converting numbers (default %.6g)
There are no explicit conversions between numbers and strings. To
awk --version
awk version 20070501
The EASY way when -v
, -V
, -version
or --version
are available (this option is available in most of cases): 当
-v
, -V
, -version
或--version
可用时的简便方法(此选项在大多数情况下可用):
awk --version
awk version 20070501
or 要么
awk -version
awk version 20070501
Now when it is not available, we go the hard way: 现在,当它不可用时,我们会努力进行 :
whereis awk
/usr/bin/awk
then 然后
what /usr/bin/awk
/usr/bin/awk
PROGRAM:awk PROJECT:awk-24
and 和
strings /usr/bin/awk | grep -Ei "version|awk"
/BuildRoot/Library/Caches/com.apple.xbs/Sources/awk/awk-24/src/b.c
version 20070501
bin/awk
-version
--version
awk %s
awkdelete
weird printf conversion %s
can't happen: bad conversion %c in format()
out of memory in awksprintf
out of memory in awkprintf
@(#)PROGRAM:awk PROJECT:awk-24
You find most all the information you were looking for by reading the strings in the binary and by using grep
to isolate what you are really looking for. 您可以通过读取二进制文件中的字符串并使用
grep
隔离真正要查找的内容来找到所需的大多数信息。 (Side note you have also find out that -version
and --version
are arguments that can be used) (附带说明,您还发现
-version
和--version
是可以使用的参数)
You can also use grep -Eai "\\bversion\\b|awk|unix" /usr/bin/awk
to reach the same result (little less readable) 您还可以使用
grep -Eai "\\bversion\\b|awk|unix" /usr/bin/awk
达到相同的结果(可读性较差)
