tldr awk
output :
$ tldr awk 1 ✘
awk
一种用于文件处理的通用编程语言。
更多信息:https://github.com/onetrueawk/awk.
- 以空格为分隔符,打印文件每行第五列(也称作字段):
awk '{print $5}' 文件名
- 以空格为分隔符,打印文件包含“foo” 的所有行的第二列:
awk '/foo/ {print $2}' 文件名
- 以逗号而不是空格作为分隔符,打印文件每行的最后一列:
awk -F ',' '{print $NF}' 文件名
- 计算文件的第一列数值之和并打印:
awk '{s+=$1} END {print s}' 文件名
- 从第一行开始,每三行打印一行:
awk 'NR%3==1' 文件名
- 根据条件不同,打印不同内容:
awk '{if ($1 == "foo") print "Exact match foo"; else if ($1 ~ "bar") print "Partial match bar"; else print "Baz"}' 文件名
- 打印第 10 列等于指定值的所有行:
awk '($10 == 指定值)'
- 打印第 10 列介于最小值和最大值之间的所有行:
awk '($10 >= 最小值 && $10 <= 最大值)'
The awk
command is located in common/awk.md
and should work on any platform (linux
, macos
, etc.), at least no matter what the -p
option is, you should get the documented results.
The reason why I have this problem is that I execute the command tldr gawk
and the output is
$ tldr gawk ✔
gawk
这是 `-p linux awk` 命令的一个别名。
- 原命令的文档在:
tldr -p linux awk
Found 2 pages with the same name under the platforms: osx, osx.
Leads me to execute tldr -p linux awk
,After I executed it, the following prompts
$ tldr -p linux awk ✔
`awk` documentation is not available.
