一次重命名多个文件

Question

我有一个大型数据集，这些文件都是这样命名的：

proportional.rank_9.cycle_10157.ratio_9
proportional.rank_9.cycle_10158.ratio_0
proportional.rank_9.cycle_10159.ratio_130
proportional.rank_9.cycle_10160.ratio_7

但当然事后看来，这将使文件中的阅读变得困难，因为我需要文件名，每个文件名可能有不同的比例。有没有办法一次重命名所有文件，以便ratio_ *消失？

理想情况下，我希望他们采用这种形式：

proportional.rank_9.cycle_10157
proportional.rank_9.cycle_10158
proportional.rank_9.cycle_10159
proportional.rank_9.cycle_10160

Answer 1

//set X to all files of the form proportional.rank
X=$(ls proportional.rank*) 

//print out to check X is set
echo $X 

//loop over all files of X
for i in $X ; do
  before_stem=${i%.ratio_*} //what I want to keep
  after_stem=${i#*.ratio_}  //what I don't want
  new_end =$(printf ".out" $after_stem) //give new ending
  mv $i ${before_stem}${new_end} //concatenate the new ending and old beginning
done

％：在％之后的模式之前取一切

英镑符号：在＃之后的模式之后采取一切

printf：就像C printf一样

proportional.rank_9.cycle_10157.ratio_9
proportional.rank_9.cycle_10158.ratio_0
proportional.rank_9.cycle_10159.ratio_130
proportional.rank_9.cycle_10160.ratio_7

变

proportional.rank_9.cycle_10157.out
proportional.rank_9.cycle_10158.out
proportional.rank_9.cycle_10159.out
proportional.rank_9.cycle_10160.out
