Linux script question: Write a script to output all of the file names that have

Question

Linux script question: Write a script to output all of the file names that have at least 2 hard links. Use the stat command similar to the script in chapter 10.F.

note: Chapter 10.F is the picture below:

f. Using the tool of your choice (egrep, awk, a shell script), provide an instruction using stat to obtain all files in /etc that have at least 7 hard links, stat -c "%n %h" gives you the name and hard links. Which files were found? Include in your answers the instruction or script that you wrote.

Explanation / Answer

Script:

ls -l etc | awk '(index($1,"d") == 0) {print "etc/" $9}' | xargs stat -c "%n %h" | awk '$2 >= 2 {print $1}'

Explanation:

ls:

-l etc     -> list out all the files and directories in etc.

awk:

index($1,”d”==0)             -> filters out directories from the ls result, leaving only files.

{print “etc/”$9}                 -> outputs relative path of the file. Eg: etc/file1.txt.

‘$2 >= 2 {print $1}’           -> prints the filename having link greater than 2.

xargs:

Takes the output of awk and inputs it to stat command.

stat:

-c            -> to provide output format.

%n          -> File name.

%h          -> Hard links.
