Renaming Multiple Files in Unix

问题

I have files in below format

EnvName.Fullbkp.schema_10022012_0630_Part1.expd
EnvName.Fullbkp.schema_10022012_0630_Part2.expd
EnvName.Fullbkp.schema_10022012_0630_Part3.expd
EnvName.Fullbkp.schema_10022012_0630_Part4.expd

I want to rename this with below files

EnvName.Fullbkp.schema_22052013_1000_Part1.expd
EnvName.Fullbkp.schema_22052013_1000_Part2.expd
EnvName.Fullbkp.schema_22052013_1000_Part3.expd
EnvName.Fullbkp.schema_22052013_1000_Part4.expd

It means I just want to rename the 10022012_0630 with 22052013_1000 what would be the commands and loop to be used to rename all the files in singe go

回答1:

This can work:

rename 's/10022012_0630/22052013_1000/' EnvName.Fullbkp.schema_10022012_0630_Part*

Given files with EnvName.Fullbkp.schema_10022012_0630_Part* pattern, it changes 10022012_0630 with 22052013_1000.

回答2:

for OLDNAME in EnvName.Fullbkp.schema_10022012_0630_Part*.expd; do
  NEWNAME=`echo "$OLDNAME" | sed 's/10022012_0630/22052013_1000/'`
  mv "$OLDNAME" "$NEWNAME"
done

A very effecient method, especially if you're dealing with thousands of files is to use bash for the string replacements and find for the lookup. This will avoid many useless forks/execve's and keep the process count down to a minimum:

for F in $(find /your/path/ -type f -name '*10022012_0630*'); do
  mv $F ${F/10022012_0630/22052013_1000};
done
