   嗯，學習了
同問一個跟此貼反向的問題，如果要是對一段數(shù)據(jù)中最后一個字段列出，而不是刪除，要怎樣做的？

dn833

那就這么搞吧
grep -Po '(?<=##)[^#\n]+$'

dn833

奇怪了。。。。代碼里不能以+$'結尾。。。。

a774050174

回復 12# dn833
awk -F'##' '{print $NF}' file
   

dn833

回復 14# a774050174


呵呵還是awk用著爽，不用去考慮復雜的正則匹配

blackold

回復 13# dn833


    可以的。

dn833

回復 16# blackold


   
那也行是我家里電腦的問題？？？12樓的代碼只要放到[code][code]里就把最后3個字符給吃了

回復 17# dn833


    哦，\n應該不能放在[]內(nèi)。
