Today, I will talk to you about using linux's dirname command to remove the non-directory part of the file name, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

The dirname command removes the non-directory portion of the file name and displays only the content related to the directory. The dirname command reads the specified pathname, preserves the last / and the characters that follow it, deletes the rest, and writes the result to standard output. If there are no characters after the last /, the dirname command uses the penultimate / and ignores all subsequent characters. Dirname and basename are usually replaced with shell internal commands to specify an output file name that is slightly different from the specified input file name.

Syntax format: dirname [parameters]

Common parameters:

-- help displays help-- version displays the version number

Reference example

The result of removing the non-directory part of / / is /:

[root@linuxcool ~] # dirname /

The result of removing the non-directory part of / a/b/ is / a:

[root@linuxcool ~] # dirname / a/b//a

The result of removing the non-catalog part of an is. :

[root@linuxcool] # dirname a.

The result of removing the non-directory part of a b is the pathname a:

[root@linuxcool ~] # dirname a/ba after reading the above, do you have any further understanding of using linux's dirname command to remove the non-directory part of the file name?
