英文:
How do I delete the first delimiter of file names in linux?
问题
我想删除Linux中文件名的第一个分隔符。
例如，
$ ls my_directory
a.b.c.txt a.b.d.txt a.b.e.txt
我希望它变成：
$ ls my_directory
ab.c.txt ab.d.txt ab.e.txt
我尝试过：
$ mv a.b* ab*
，但不幸的是这不起作用。
我该怎么做？
谢谢提前。

Use a replace once parameter expansion method if you're using Bash:
for f in a.b*; do
mv -i -- "$f" "${f/.}"
done
See Shell Parameter Expansion.
If you're using a POSIX shell, you can use ${f%%.*}${f#*.} or in the case of a known prefix like a.b, simply ab${f#a.b}.
