#!/bin/sh

#replace all files ended witn .f77 to .f90 in a directory

for filename in *.f77
do 
    #echo $filename
    #b= echo $filename | cut -d. -f1
    #echo $b    
    mv "${filename}" "${filename%.f77}.f90"    
done

这里有一个使用命令行Groovy的方法:

groovy -e 'new File(".").eachFileMatch(~/fgh.*/) {it.renameTo(it.name.replaceFirst("fgh", "jkl"))}'

使用重命名:

$ renamer --find /^fgh/ --replace jkl * --dry-run

一旦您对输出看起来正确感到满意，就删除——dry-run标志。

(在我的Mac上)用Ruby做这个要容易得多。下面是两个例子:

# for your fgh example. renames all files from "fgh..." to "jkl..."
files = Dir['fgh*']

files.each do |f|
  f2 = f.gsub('fgh', 'jkl')
  system("mv #{f} #{f2}")
end

# renames all files in directory from "021roman.rb" to "021_roman.rb"
files = Dir['*rb'].select {|f| f =~ /^[0-9]{3}[a-zA-Z]+/}

files.each do |f|
  f1 = f.clone
  f2 = f.insert(3, '_')
  system("mv #{f1} #{f2}")
end

#!/bin/sh

#replace all files ended witn .f77 to .f90 in a directory

for filename in *.f77
do 
    #echo $filename
    #b= echo $filename | cut -d. -f1
    #echo $b    
    mv "${filename}" "${filename%.f77}.f90"    
done

并不是每个系统都需要重命名。如果没有，就用壳层 本例使用bash shell

for f in fgh*; do mv "$f" "${f/fgh/xxx}";done
