How to Find All Files with a Specific File Extension in Linux
How can we find all
.md files in a directory? Well, there are multiple ways to do this.
The first way is to use
We can use
ls to list all
.md files in the current directory
We can use
find to list all
.md files in the current directory as well as all subdirectories.
find . -name "*.md"
grep -i \.md$
grep case insensitive so that it matches
.md as well as
\. escapes the period and searches for a literal period. Without the backslash
\, the period
. matches any non space or newline character.
md searches for the text
$ is an end of line character. It ensures that the
md is the last text in that line.
Let’s try it without the
grep -i \.md
This command would match all kinds of file extensions:
$ is kind of important.
We can also add
-r to recursively search every subdirectory as well as the current directory.
grep -ir \.md$
However, since grep searches file contents, using only
grep will return file contents that have
.md in them.
As a result, we can just use
find and pipe the output to
grep to only search filenames.
find . | grep \.md$
. will only search in the current directory. Feel free to change this to whatever directory path you want to search through.
The reason why we would ever use this method over just
find is if we want to leverage the power of regular expressions in our
