我這樣寫為什么不行啊(想匹配wlan ap 到#之間的行 變成一行后換行打印所需要的字段，得不到想要的結(jié)果)這個(gè)錯(cuò)在什么地方請(qǐng)各位大俠指教
awk '/wlan\ ap/,/#/ {printf $0}{print ""}'  filename | awk '{print $3,$5,$12}'

    awk '/wlan/{printf $3"\t"$(NF-2);getline;getline;print "\t"$2}'

waker

/wlan\ ap/,/#/ {printf $0}{print ""}分開看
/wlan\ ap/,/#/ {printf $0}
模式:/wlan\ ap/,/#/  動(dòng)作:printf $0

{print ""}
模式:缺省      動(dòng)作print ""

waker

1. awk -vRS=# -F'\n' '/wlan/{print $1,$2,$3}' urfile

對(duì)于3樓我想請(qǐng)教一下（不好意思太弱了，不是很明白你的意思，能說的再詳細(xì)點(diǎn)嗎），如果按我的思路應(yīng)該怎么寫這個(gè)語句啊。我就是想操作wlan ap 到#這段文字。

或許你是這個(gè)想法?不太清楚

jiejie455

awk 'BEGIN{RS="#\n";FS="[ \n]"}/wlan\ ap/{print $3,$5,$12}' sample.data

baoyu05

{print ""}
這大括號(hào)之間是并列的，所以你文件有多少行，就會(huì)打印多少個(gè)空行。
因?yàn)閜rintf是沒有換行的，你的意思可能是每匹配一塊之后就換行，如果是這樣的話，你的代碼可以改成這樣：

1. awk '/wlan\ ap/,/#/{printf $0" ";if($0 ~/#/)print ""}' a|awk '{print $3,$5,$12}'
