就是将人名后面括号里的年代放置在页码的后面，同时去掉括号。谢谢！

第一个问题

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

复制代码

第二个问题还没看懂你的意思

再简化：

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

比如说这个：
\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.

变成这样：
\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，变成”226--236，2002.“

确实还可以简化，谢谢Tim。

1. 
   
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

贴子超过5000就变成“法师”了？
