Two. linux file name length limit:

The file name length in the Linux preset EXT2/EXT3 filesystem is limited to:

The maximum allowable file name for a single file or directory is 255 characters, including the full path name and the full file name of the directory (/) with 4,096 characters.

Three. Limitations of characters for Linux filenames:

Some special characters should usually be avoided due to some instructions in Linux under the text interface. For example:

* ? > <; &! [ ] | \ ' "' () {}

Because these symbols in the text interface, there is a special meaning. At the same time, since the command release often uses options such as-option, it is best to avoid naming the file name at the beginning of-or +.
