# The `basename` command
|
|
|
|
The `basename` is a command-line utility that strips directory from given file names. Optionally, it can also remove any trailing suffix. It is a simple command that accepts only a few options.
|
|
|
|
### Examples
|
|
|
|
The most basic example is to print the file name with the leading directories removed:
|
|
|
|
```bash
|
|
basename /etc/bar/foo.txt
|
|
```
|
|
|
|
The output will include the file name:
|
|
|
|
```bash
|
|
foo.txt
|
|
```
|
|
|
|
If you run basename on a path string that points to a directory, you will get the last segment of the path. In this example, /etc/bar is a directory.
|
|
|
|
```bash
|
|
basename /etc/bar
|
|
```
|
|
|
|
Output
|
|
|
|
```bash
|
|
bar
|
|
```
|
|
|
|
The basename command removes any trailing `/` characters:
|
|
|
|
```bash
|
|
basename /etc/bar/foo.txt/
|
|
```
|
|
|
|
Output
|
|
|
|
```bash
|
|
foo.txt
|
|
```
|
|
|
|
### Options
|
|
|
|
1. By default, each output line ends in a newline character. To end the lines with NUL, use the -z (--zero) option.
|
|
|
|
```bash
|
|
$ basename -z /etc/bar/foo.txt
|
|
foo.txt$
|
|
```
|
|
|
|
2. The `basename` command can accept multiple names as arguments. To do so, invoke the command with the `-a` (`--multiple`) option, followed by the list of files separated by space. For example, to get the file names of `/etc/bar/foo.txt` and `/etc/spam/eggs.docx` you would run:
|
|
|
|
```bash
|
|
basename -a /etc/bar/foo.txt /etc/spam/eggs.docx
|
|
```
|
|
|
|
```bash
|
|
foo.txt
|
|
eggs.docx
|
|
```
|
|
|
|
### Syntax
|
|
|
|
The basename command supports two syntax formats:
|
|
|
|
```bash
|
|
basename NAME [SUFFIX]
|
|
basename OPTION... NAME...
|
|
```
|
|
|
|
### Additional functionalities
|
|
|
|
**Removing a Trailing Suffix**: To remove any trailing suffix from the file name, pass the suffix as a second argument:
|
|
|
|
```bash
|
|
basename /etc/hostname name
|
|
host
|
|
```
|
|
|
|
Generally, this feature is used to strip file extensions
