文件重命名/删除

我有几个像这样的文件 -

* .ssss和* _passive.sss

如果我有一个名为blah1.sss和blah1_passive.sss的文件,我想摆脱blah1.sss并重命名为blah1_passive.sss。但是,如果我没有blah1_passive.sss,我想记录文件名并保留blah1.sss。

我能够找到所有* _passive.sss文件,但我想知道awk / sed etc命令可以将* _passive.sss重命名为* .sss。

编辑:现在我有这个,但os.rename不会覆盖文件,我需要覆盖它。

import os, fnmatch

def locate(pattern, root=os.curdir):

    #ignore directories- uncomment to make ignore work
    #ignored = ["0201", "0306"]
  for path, dirs, files in os.walk(os.path.abspath(root)):
         #for dir in ignored:                  # if dir in dirs:                        #dirs.remove(dir)
    for filename in fnmatch.filter(files, pattern):
       yield os.path.join(path, filename)



for filename in locate("*_passive.sss"):
               #found the files that i want to rename, but os.rename() refuses to overwrite !! 
    newfilename=filename.rstrip("_passive.sss") + ".sss"
    os.rename(filename,newfilename)

在Unix中,您可以在Bourne shell中使用以下命令(即sh / bash):

for f in *_passive.sss; do mv -v $f `basename $f _passive.sss`.sss; done

这个shell脚本可以解决这个问题:

while read f; do
    fp="`echo "$f" | sed -nr 's|(.*)(\.sss)|\1_passive\2| p'`"
    if [ -f "$fp" ]; then mv "$fp" "$f"
    else  echo "file $fp missing" >> missing.log
    fi
done<<<"`ls -1 *.sss | grep -v _passive.sss`"

还会将遗失的_passive个文件报告给missing.log

这是一个python解决方案:

import os
from glob import glob

# Write out test files.
with open('foo.sss', 'w'):  pass
with open('foo_passive.sss', 'w'):  pass
with open('bar.sss', 'w'):  pass

# Rename files.
files = glob('*.sss')
for filename in files:
  if filename.endswith('_passive.sss'):  continue
  passive_fname = filename.split('.sss')[0] + '_passive.sss'
  if passive_fname in files:
    os.remove(filename)
    os.rename(passive_fname, filename)
  else:
    print 'no passive: ', filename
