Why is file management important every day?

Which of the following best explains why file management is a daily task in Linux command line work?

A Files constantly change and organizing them daily helps keep data accessible and secure.

B Once files are created, they never need to be moved or deleted.

C File management is only needed when installing new software.

D Files automatically organize themselves without user intervention.

💡 Hint

Think about how files accumulate and change over time.

Files are created, modified, and deleted regularly. Managing them daily prevents clutter and data loss.

💻 Command Output

Output of listing files after daily cleanup

What is the output of this command sequence after daily file cleanup? Commands: mkdir testdir cd testdir touch file1 file2 file3 rm file2 ls

Linux CLI

mkdir testdir
cd testdir
touch file1 file2 file3
rm file2
ls

A

file2
file3

B

file1
file2
file3

C

file1
file3

D

file1
file2

💡 Hint

Check which file was removed before listing.

The 'rm file2' command deletes file2, so only file1 and file3 remain.

Correct command to move files daily

Which command correctly moves all '.log' files from the current directory to a folder named 'logs' as part of daily file management?

A mv logs/ *.log

B mv *.log logs/

C move *.log logs/

D mv *.log to logs/

💡 Hint

The 'mv' command moves files; check the order of arguments.

'mv *.log logs/' moves all files ending with .log into the logs directory.

Why does this daily cleanup script fail?

This script is meant to delete all '.tmp' files daily but fails. Why? Script: rm *.tmp mkdir tmp_files mv *.tmp tmp_files/

A The 'rm *.tmp' deletes all .tmp files before 'mv' can move them, so 'mv' fails.

B 'mkdir tmp_files' should come after 'mv' command.

C The 'rm' command syntax is incorrect; it needs a '-r' flag.

D The script lacks a shebang line, so it won't run.

💡 Hint

Think about the order of deleting and moving files.

The script deletes all .tmp files first, so the move command has no files to move and fails.

🚀 Application

Automate daily file archiving with a script

You want to create a daily script that archives all '.txt' files in the 'docs' folder into a zip file named with the current date (e.g., 2024-06-15.zip). Which script snippet correctly does this?

A zip "$(date +%F).zip" docs/*.txt

B zip docs/*.txt "$(date +%F).zip"

C zip docs/ "$(date +%F).zip" *.txt

D zip "$(date +%Y-%m-%d).zip" docs/*.txt

💡 Hint

Check the date format and argument order for the zip command.

Option D uses the correct date format and places the zip file name first, then the files to archive.
