我想修改类似如下一批文件的文件名：
AA01_01.txt
AA01_02.txt
AA01_03.txt
AA01_04.txt
修改成
BB02_01.txt
BB02_02.txt
BB02_03.txt
BB02_04.txt
把文件名的头换下。
==============================================================
for x in `seq 1 4`;do mv AA01_0${x}.txt BB01_0${x}.txt;done
今天才知道rename这个命令...而且看这个可以用perlexpr...
perl:~# rename
Usage: rename [-v] [-n] [-f] perlexpr [filenames]
rename "s/AA/BB/" *.txt
