In this case, first, we need the current script’s path, and from it, we use dirname to get the directory path of the script file. Once we have that, we cd into the folder and print the working directory. To get the full or absolute path, we attach the basename of the script fil...
There can be many reasons why you'd want to get the exact location of your currently running script. For example to calculate the relative path in a reliable way. Luckily there is a command called realpath that will calculate and print the absolute path of a given path. Let's see ...
#!/usr/bin/env bash script_dir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" script_filename="$(basename "${BASH_SOURCE[0]}")" echo "this bash script's dir is ...: $script_dir" echo "this bash script's file name is..: $script_filename" Home Snippets...
In Bash, the realpath is used to get the absolute path of the script or a directory. Now, what is the absolute path? There are two types of paths:Absolute Path: It retrieves the script’s full path starting from the file system’s root. For example: If our current script is Bash...
As illustrated above, using the command realpath, we can easily determine the absolute path of the file. We can also use realpath bash command along with the BASH_SOURCE environment variable to get the script location. The sample script: #!/usr/bin/env bash MYDIR=$(dirname "$(realpath "...
Bash script may need to get its own path. In normal Bash script, $0 is the path to the script. However, when a script is sourced, such as . a.sh, a.sh‘s $0 does not give a.sh while the caller’s name. How to reliably get a bash script’s own path no matter whether the ...

# 输出: 长度x高度 $ get_window_size 1200x800 # 输出(失败): $ get_window_size x获取当前光标位置用纯bash创建TUI时,是很有用的。 TUI是指文本用户界面(Text-based User Interface),通过文本实现交互窗口展示内容,定位光标和鼠标实现用户交互。
# Check before running: Need 3 arguments to run the script properly if [[ $# -lt 2 ]]; then echo "Didn't run, because the number of argument needs to be 2" echo "EX: $0 [/path/to/file] [new_name_prefix]" exit 0 fi
Script arguments:red First arg:red.Second arg:.Numberofarguments:1 用户输入 如果你正在为自己或其他人编写Bash程序,那么获取用户输入的一种方式就是指定用户提供给程序的参数,正如我们在前一节中讨论的那样。你还可以通过使用read命令暂时停止程序的执行,要求用户在命令行上输入一个字符串。让我们写一个小脚本,...
