Removing the File Extension
To remove the file extension from a file name, you can use the ${VARIABLE%.*} syntax, where VARIABLE is the name of the file with the file extension. For example:
filename=”file.txt”
no_extension=${filename%.*}
echo “The file name without the extension is: $no_extension”
This would output the following:
The file name without the extension is: file
Bash Scripting – File Extension
Bash scripting is a powerful tool for automating tasks and working with files in the command line. One important aspect of working with files in bash is understanding how to handle file extensions. In bash, a file extension is the portion of a file name that follows the last period (.) in the file name. For example, in the file name “file.txt“, the file extension is “txt“. File extensions are used to indicate the type of file and to determine which programs should be used to open the file.
Bash scripting is a powerful tool for automating tasks and manipulating files in Linux and Unix systems. One important aspect of bash scripting is working with file extensions. In this article, we will discuss various ways to work with file extensions in bash scripting.
The first step in working with file extensions is to extract the extension from a file name. This can be done using the ‘basename’ and ‘dirname’ commands, which can be used to extract the basename and directory name of a file, respectively. For example, to extract the extension of a file named “example.txt”, we can use the following command:
extension="${file##*.}"
There are several methods to work with file extensions in bash scripting.
