SED或AWK提取值

我有一個文件作爲如下：SED或AWK提取值

通過使用sed或awk或什麼，我想在下面的輸出：

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 
...

如何實現這一目標？

什麼是你列之間的那些大的差距？他們是製表符還是特定數量的空白字符或其他內容？ –

與以往一樣，你的答案會使其他人」業餘「_和_」愚蠢「_ +1 – Inian

這是簡短和更好的答案+1024 – Xianlin

cat input_list_file | awk '{print $5,$8,$12,$16}' | sed 's/level=//g' | sed 's/ESSID://g' | sed 's/"//g'

可縮寫爲'awk'{print $ 5，$ 8，$ 12，$ 16}'input_list_file | sed -E's/level = | ESSID：|「// g'' :) – Sundeep

當你使用awk時，你永遠不需要sed，而當你使用任何東西時你永遠不需要cat（谷歌UUOC）。「是一種反模式 –

隨着grep和pcre

$ grep -oP 'Address: \K\S+|Signal level=\K\S+|ESSID:"\K[^"]+|\d+ms' ip.txt | pr -4 -ats' ' 
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 
AC:F1:DF:26:FD:E4 -71 iNote 80ms 
74:A2:E6:CF:94:D1 -58 eduroam 80ms 
74:A2:E6:CF:94:D3 -59 \x00 80ms 
74:A2:E6:CF:94:D5 -61 \x00 80ms 
74:A2:E6:CF:94:D8 -60 \x00 80ms

採用積極的回顧後修剪字符串匹配

整齊樣式它，離開了分離器（這裏不顯示，但列排隊）

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

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

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

產生一個奇特的輸出格式如預期。

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 
AC:F1:DF:26:FD:E4 -71 iNote   80ms 
74:A2:E6:CF:94:D1 -58 eduroam   80ms

隨着桑達，因爲每個人都希望用awk。我使用的分組：

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 
08:86:3B:30:88:6C -68 SoundEyeWifi 80ms 
00:0B:81:9A:5F:37 -77 IROAD_AEV_9A5F37 80ms
