推荐答案

这些功能强大的命令将非常快速地进行大量更改-请测试一小部分数据的副本.

These are powerful commands that will make lots of changes very rapidly - please test on a copy of a small subset of your data.

方法1-使用重命名"(Perl工具)

这应该与rename一起使用，您可以通过以下方式将其安装在macOS上:

This should work with rename which you can install on macOS with:

brew install rename

命令为:

rename --dry-run -N "00001" 's/.jpg$/_$N.jpg/' *jpg

删除--dry-run以便实际执行命令，而不仅仅是告诉您它将执行的操作.

Remove the --dry-run to actually execute the command rather than just tell you what it would do.

方法2-使用GNU并行

或者，它应该与 GNU Parallel 一起使用，您可以通过以下方式将其安装在macOS上:

Alternatively, this should work with GNU Parallel which you can install on macOS with:

brew install parallel

命令为:

find . -name \*.jpg -print0 | parallel -0 --dry-run mv {} {.}_{#}.jpg

其中:

• {}表示当前文件" ，
• {.}表示当前文件减去扩展名" ，并且
• {#}表示(顺序)作业编号"

• {} means "the current file",
• {.} means "the current file minus extension", and
• {#} means "the (sequential) job number"

删除--dry-run以便实际执行命令，而不仅仅是告诉您它将执行的操作.

Remove the --dry-run to actually execute the command rather than just tell you what it would do.

您提到您想要一个偏移量，因此以下内容的偏移量为3:

You mentioned you wanted an offset, so the following works with an offset of 3:

find . -name \*.jpg -print0 | parallel -0  'printf -v new "%s_%05d.jpg" "{.}" $(({#}+3)); echo mv "{}" "$new"'

---

方法3-无需其他软件

这只能使用标准的内置工具来工作:

This should work using just standard, built-in tools:

#!/bin/bash

for f in *.jpg; do
   # Figure out new name
   printf -v new "%s_%05d.jpg" "${f%.jpg}" $((cnt+=1))

   echo Would rename \"$f\" as \"$new\"
   #mv "$f" "$new"
done

删除倒数第二行中的#即可进行重命名.

Remove the # in the penultimate line to actually do the rename.

方法4-无需其他软件

这应该仅使用标准的内置工具即可工作.请注意，macOS附带了Perl，并且它应该更快，因为它不会像以前的方法那样为40,000个文件中的每个文件启动新的mv进程.相反，Perl仅启动一次，它读取find传递给它的以空值结尾的文件名，然后为每个文件执行库调用:

This should work using just standard, built-in tools. Note that macOS comes with Perl installed, and this should be faster as it doesn't start a new mv process for each of 40,000 files like the previous method. Instead, Perl is started just once, it reads the null-terminated filenames passed to it by find and then executes a library call for each:

find . -name \*.jpg -print0 | perl -0 -e 'while(<>){ ($sthg=$_)=~s/.jpg//; $new=sprintf("%s_%05d.jpg",$sthg,++$cnt); printf("Rename $_ as $new\n"); }'

如果看起来正确，请更改最后一行，以便实际上进行重命名，而不只是告诉您它将做什么:

If that looks correct, change the last line so it actually does the rename rather than just telling you what it would do:

find . -name \*.jpg -print0 | perl -0 -e 'while(<>){ ($sthg=$_)=~s/.jpg//; $new=sprintf("%s_%05d.jpg",$sthg,++$cnt); mv $_, $new; }'
