DRAG DROP -
As a Systems Administrator, to reduce disk space, you were tasked to create a shell script that does the following:
Add relevant content to /tmp/script.sh, so that it finds and compresses rotated files in /var/log without recursion.
INSTRUCTIONS -
Fill the blanks to build a script that performs the actual compression of rotated log files.

Correct script code (tested) #!bin/bash #name:script.sh find /var/log -maxdepth 1 -type f | grep "log.[1-6]$" > /tmp/tempfile for filename in $(cat /tmp/tempfile) do gzip $filename done
Wrong. First, the question does not ask for files with "log" in the name (it doesn't even ask for log files - it says "related files"). Second, some of the files in /var/log do not have log or .log anywhere in the filename (e.g. messages, secure, spooler, etc.) and would be missed using your syntax. Third, I seriously doubt you tested it if your first line is incorrect... It's #!/bin/bash Your version will (likely) create an empty tempfile and compress nothing. And, yes, I've tested your solution (and mine). The correct answer is: #!/bin/bash #name: script.sh find /var/log -type f -maxdepth 1 | grep "$1" > /tmp/tempfile for filename in $(cat /tmp/tempfile) do gzip $filename done
could someone help with this one? grep $1 doesn't look right, I think it should be grep "log.[1-6]$
grep "$1" will search all the file named with the positional parameter and put the file name in to tempfile
Hi @ssc1982, thanks for your reply and help. the question is not mentioning that the script will have positional parameters and "log.[1-6]$" regular expression will allow grep to find those logs... rights? Thanks again
So what is the answer?

It says in the question that " Add relevant content to /tmp/script.sh, so that it finds and compresses rotated files in /var/log without recursion" , there are a variety of different logs under the directory /var/log, not all the log start with log.*, using a positional parameter better match "Add relevent content to the /tmp/script.sh", I think
I tested it and it worked with me by using "$log.[1-6]$" It didn't return any results with "log.[1-6]$"
