如何使用Shell脚本重命名文件？

Question

I have files named like this:

• 2014-8-1.txt
• 2014-08-02.txt
• 2014-9-03.txt
• 2014-09-4.txt

How can I rename those files to the following names? ('-' hyphens will be replaced with '_' underscores.)

• 2014_8_1.txt
• 2014_08_02.txt
• 2014_9_03.txt
• 2014_09_4.txt

Answer 1

Try this:

mv `ls *-*.txt` `ls *-*.txt | sed 's/-/_/g'`

mv - renames file
ls with wildcard - will list all the files with "-" in it
sed - will search for - in filename and replace it with _ any number of occurances.

Answer 2

您可以使用以下find ：

find . -type f -name [0-9]*-[0-9]*-[0-9]*.txt -print0 | xargs -0 -I {} bash -c 'f="{}"; echo mv "$f" "${f//-/_}"'
