黑哥，名字倒換處理得很好。有一個問題就是年代沒有了。我能不能將更多的幾條記錄給你，你再幫我分析以下。

就是將人名后面括號里的年代放置在頁碼的后面，同時去掉括號。謝謝！

2. sed -r 's/(\w+,) (\w.)/\2\1/g' 1.txt

第二個問題還沒看懂你的意思

再簡化：

sed -r ':a;N;/\n\n$/!{$!ba};s/\b([A-Z][A-Za-z-]+), *([A-z.]+)/\2\1/g;s/\(([0-9]{4})\)(.*[^\n])/\2 \1/' urfile

比如說這個：
\bibitem{guo2002}  L.Guo (2002). \newblock {$H_{\infty }$}

output feedback control for delay systems with nonlinear and

parametric uncertainties. \newblock \emph{IEE Proc. Control Theory

Appl.}, 149: 226--236.

變成這樣：
\bibitem{guo2002}  L.Guo， \newblock {$H_{\infty }$}

output feedback control for delay systems with nonlinear and

parametric uncertainties. \newblock \emph{IEE Proc. Control Theory

Appl.}, 149: 226--236，2002.

即，(2002)放在“226--236，”后面，變成”226--236，2002.“

確實還可以簡化，謝謝Tim。

2. sed ':a;$bn;N;/\n\n$/!ba;:n;s/ \([A-Z][A-Za-z_-]\+\),[ \n]*\([A-Z]\.\)/ \2\1/g;s/(\([0-9]\{4\}\))\(.*\)\([^\n]\)/\2, \1\3/' urfile

有年代啊。
作了些格式調(diào)整。
