IGNOU BCS-062-E-Commerce, Latest Solved Assignment (July 2023 - January 2024 )
Q3. (A) Write a shell script to delete all files from a folder which are having numeric digit in the file name.
(B) As a Windows 2000 Administrator, enable and configure IP sec policy on local computer. Also, enable it for entire domain. Explain with step by step procedure.
Sol) (A)
shell
#!/bin/bash
# Get the current directory
current_directory=$(pwd)
# Get the list of files in the current directory
files=$(ls)
# Loop through the list of files
for file in $files; do
# Check if the file name contains a numeric digit
if [[ “$file” =~ \d ]]; then
# Delete the file
rm -f $file
fi
done
To run the script, you can save it as a file called
`delete_files_with_digits.sh` and then make it executable using the following command:
chmod +x delete_files_with_digits.sh
You can then run the script using the following command:
./delete_files_with_digits.sh
The script works by first getting the current directory. It then gets the list of files in the current directory. It then loops through the list of files and checks if each file name contains a numeric digit. If the file name contains a numeric digit, the script deletes the file.
For example, if the current directory contains the following files:
* file1.txt
* file2.docx
* file3.png
* file4.123.jpg
The script will delete the files `file4.123.jpg` and `file3.png`.
