如何在Linux中将所有包含下划线的文件和文件夹重命名为连字符

Question

I want to rename all files and folder containing underscore in name and replace underscore with hyphen.

Currently I am using following code,

rename '_' '-' */*/*

It was working but now it is showing me "Argument list too long"

You can try this:

$ tree foo
foo
├── dir_1
│   └── foo_file_2
└── file_1

1 directory, 2 files
$ for ft in d f; do find foo -type $ft -execdir sh -c 'mv "$0" "${0//_/-}"' {} \; ; done 2>/dev/null
$ tree foo
foo
├── dir-1
│   └── foo-file-2
└── file-1

1 directory, 2 files

This renames all directories and then all files (the for loop over df ) because I haven't been able to make it do all renaming in one iteration.
