Bash - get current script directory path
In this short article, we would like to show how to get the currently executed script directory path in Bash.
Quick solution:
xxxxxxxxxxSCRIPT_DIR=$(cd "$(dirname "${BASH_SOURCE[0]}")" &> /dev/null && pwd)echo $SCRIPT_DIR;Notes:
- no metter from where we will execute script,
$SCRIPT_DIRwill indicate directory where script is located, e.g./c/test/script.shwith above script will print/c/text,- the solution is not working if last component of the script path is a symlink, but it is enought for most cases.
Screenshot:
If you want to get a solution that returns Windows or Linux formatted path try this solution:
xxxxxxxxxxSCRIPT_DIR=$(cd "$(dirname "${BASH_SOURCE[0]}")" &> /dev/null && (pwd -W 2> /dev/null || pwd))echo $SCRIPT_DIR; // Format under Windows: C:/test // Format under Linux/Unix: /c/test
There are other ways how to get executed script directory path, we will focus on 2 of them. The main idea is to get script full path with readlink or realpath command and later extract directory path with dirname.
That approach doesn't prevent situations when the script is attached as a source (source path/to/script.sh) returning called script path - is enough when we have just one *.sh script.
script.sh file content:
xxxxxxxxxxSCRIPT_PATH=`readlink -f "$0"`SCRIPT_DIR=`dirname "$SCRIPT_PATH"`echo $SCRIPT_DIR;Executing from /c location:
xxxxxxxxxx$ pwd/c$ test/script.sh/c/test
