在终端中重命名文件的脚本

Question

I am writing a script in bash to manage files. I need to add a functionality to change files name. To get a file I use zenity File Selection Dialog. After this operation I have a variable with path to this file: /home/user/Desktop/name_of_file . How can I remove current file name from this string and put there a new one?

Answer 1

With Bash's Parameter Expansion :

name="/home/user/Desktop/name_of_file"
new="${name%/*}/new_name_of_file"
echo "$new"

Output:

/home/user/Desktop/new_name_of_file
