我有一个文件作为如下：SED或AWK提取值

Cell 01 - Address: 58:6D:8F:D1:A9:07     Quality=52/70 Signal level=-58 dBm      Encryption key:on     ESSID:"money-plant"     Extra: Last beacon: 80ms ago

通过使用sed或awk或什么，我想在下面的输出：

58:6D:8F:D1:A9:07 -58 money-plant 80ms 
10:C3:7B:55:73:38 -65 JDBX 80ms 
64:09:80:5F:7D:AF -78 Next 80ms 
64:66:B3:9D:82:76 -71 home-router 80ms 
...

如何实现这一目标？

什么是你列之间的那些大的差距？他们是制表符还是特定数量的空白字符或其他内容？ –

可缩写为'awk'{print $ 5，$ 8，$ 12，$ 16}'input_list_file | sed -E's/level = | ESSID：|“// g'' :) – Sundeep

当你使用awk时，你永远不需要sed，而当你使用任何东西时你永远不需要cat（谷歌UUOC）。 “是一种反模式 –

随着grep和pcre

$ grep -oP 'Address: \K\S+|Signal level=\K\S+|ESSID:"\K[^"]+|\d+ms' ip.txt | pr -4 -ats' '

整齐样式它，离开了分离器（这里不显示，但列排队）

使用GNU awk和自己看中printf从String-Manipulation Functions和substr，这是可以做到的

awk '{split($8, a, "level=");b=substr($12,7);gsub(/"/,"",b);printf "%-16s %s %-16s %-16s\n", $5, a[2], b, $16}' file

产生一个奇特的输出格式如预期。

58:6D:8F:D1:A9:07 -58 money-plant  80ms 
10:C3:7B:55:73:38 -65 JDBX    80ms 
64:09:80:5F:7D:AF -49 NExT    80ms 
64:66:B3:9D:82:76 -61 home-router  80ms 
08:86:3B:30:88:6C -68 SoundEyeWifi  80ms 
00:0B:81:9A:5F:37 -77 IROAD_AEV_9A5F37 80ms 
74:A2:E6:CF:94:D0 -62 NUS    80ms

随着桑达，因为每个人都希望用awk。我使用的分组：

sed 's/\(^.*Address: \)\([A-Z0-9:]*\)\(.*level=\)\(\-[0-9]*\)\(.*ESSID:\"\)\(.*\)\(\".*beacon: \)\(.*\)\(ago.*\)/\2 \4 \6 \8/g' tmp

OUTPUT：

58:6D:8F:D1:A9:07 -58 money-plant 80ms 
10:C3:7B:55:73:38 -65 JDBX 80ms 
64:09:80:5F:7D:AF -49 NExT 80ms 
64:66:B3:9D:82:76 -61 home-router 80ms
