Question: see the requirements of a brother. I will cut the figure below.

In particular, some brothers are very careful. The above is about removing _ finished. My answer is to remove finished, but it does not affect the overall situation. Please pay attention to it.

Answer:
[Prepare Test Data]
Mkdir/oldboy cd/oldboy
Touch stu_102999_1_finished.jpg
Touch stu_102999_2_finished.jpg
Touch stu_102999_3_finished.jpg
Touch stu_102999_4_finished.jpg
Touch stu_102999_5_finished.jpg

Method 1: shell script for loop combined with sed
[Check Data]
[Root @ oldboy] # ll
Total 4
-Rw-r -- 1 root 85 Oct 2 :54 oldboy_modi_file.sh
-Rw-r -- 1 root 0 Oct 2 stu_102999_1_finished.jpg
-Rw-r -- 1 root 0 Oct 2 :50 stu_102999_2_finished.jpg
-Rw-r -- 1 root 0 Oct 2 :50 stu_102999_3_finished.jpg
-Rw-r -- 1 root 0 Oct 2 12:50 stu_102999_4_finished.jpg
-Rw-r -- 1 root 0 Oct 2 :50 stu_102999_5_finished.jpg

[Development script]
[Root @ oldboy] # cat oldboy_modi_file.sh
#! /Bin/sh
For file in 'ls./*. jpg'
# Shell script for loop, file is the variable to get the results file name of ls./*. jpg in turn
Do
Mv $ file 'echo $ file | sed's/finished // g''
# Use the mv command to change the file. splicing the new file name string is the focus of this question.
Done
# Note: Through this question, you can learn how to use the for loop and how to use commands such as mv and sed.

[Execute the script]
[Root @ oldboy] # sh oldboy_modi_file.sh

[Check Results]
[Root @ oldboy] # ll
