Linux / UNIX: Rules For Naming File And Directory Names
You can use other special characters such as blank space, but they are hard to use and it is better to avoid them.In short, filenames may contain any character except / (root directory), which is reserved as the separator between files and directories in a pathname. You cannot use the null character.No need to use . (dot) in a filename. Some time dot improves readability of filenames. And you can use dot based filename extension to identify file. For example:
Most modern Linux and UNIX limit filename to 255 characters (255 bytes). However, some older version of UNIX system limits filenames to 14 characters only.A filename must be unique inside its directory. For example, inside /home/vivek directory you cannot create a demo.txt file and demo.txt directory name. However, other directory may have files with the same names. For example, you can create demo.txt directory in /tmp.
- .sh = Shell file
- .tar.gz = Compressed archive
