And yet, regardless of how much redundancy you build into your setup, there's always the potential for unexpected issues. You must know the tools and procedures to help you solve unpleasant surprises.

Getting an invalid argument error for these and similar files:

/sys/fs/cgroup/systemd/user.slice/user-42.slice/cgroup.event_control

when backing up the root directory (excluding /home, /mnt, /proc, /tmp directories).

Are these files to be excluded?

Am writing a bash script that uses grep to search phrases and prints them on terminal. I want the user to have the possibility of using the context options of grep (-C, -A, -B). I made an indexed array ictx, which I want to use for making the context arguments to grep (-C NUM, -A NUM, -B NUM, -A NUM1 -B NUM2).

Would help having some advice on how I can neatly handle the making of ICTX with tho code listed below.

Code:   while (( $# > 0 )); do
  case "$1" in
    ("-C"|"--context")
        ctx="$2" ; shift ; shift ;;
   
    ("--Bfc"|"--before-context")
        bfctx="$2" ; shift ; shift ;;

    ("--Afc"|"--after-context")
        afctx="$2" ; shift ; shift ;;
  esac
  done

  [[ -z "$ctx" ]] && ctx=8
  ictx=( -C "$ctx" )
  ictx=( -A "$afctx" )
  ictx=( -B "$bfctx" )

  grep -ni "${ictx[@]}" -e "$ptrn" -- "$fl"

In my system using cron.d there is a file which is repeatdly run. It generates an answer to my exercise.
I used ls /etc/cron.d I have access to this file.
It is alice.sh I use
Code:
sh /tmp/tmp.6vOX6HxEg1/alice.sh my resposne
Code: alice@ip-10-0-119-57:~$ sh /tmp/tmp.6vOX6HxEg1/alice.sh
cat: /root/archive/secret.txt: Permission denied
/opt/create_and_delete_file_from_args.sh: line 7: /tmp/tmp.6vOX6HxEg1/151504505d2d29ecad318671b5476560: Permission denied
rm: cannot remove '/tmp/tmp.6vOX6HxEg1/151504505d2d29ecad318671b5476560': No such file or directory It generates a file that I need to read but it is as I read deleted.
I was thinking to run my own script which will listen and copy all kind of files when created to another directory. But I am green I do not know how to write own listener in bash linux.
Thanks in advance.


this is alice.sh

Code: #!/usr/bin/env bash
 
secret_script_path="/opt/create_and_delete_file_from_args.sh"
secret_directory="/tmp/tmp.6vOX6HxEg1"
secret_file="TUApZ7WH3C7n"

bash "${secret_script_path}" "${secret_directory}" $(echo "${secret_file}" | md5sum | awk '{ print $1 }') first edit:
this next .sh file has got a method that create and after 0,005s delete file with information.


Code: #!/usr/bin/env bash

"secret_directory=$1
secret_file=$2
exercise_flag=$(cat "/root/archive/secret.txt")

echo "${exercise_flag}" > "${secret_directory}/${secret_file}"

sleep 0.005"

rm "${secret_directory}/${secret_file}"

//normally here is rm (Deleting file) I can't edit this file it is only readable I wanted to delete rm and add cat after creating.
There was an idea to create another .sh file without rm and with cat, but I can't do it.
After leaving vim I used
Code: :w !sudo tee % > /dev/null but there is error with

Code: Username is not in the sudoers file. This incident will be reported if I'm leaving with :w then "E212 Can't open file for writing"

Someone asked me recently if Linux Mint is actually Ubuntu why not just install Ubuntu and I did not know how to answer them.

The headlines went to the long-anticipated arrival of RHEL 9, but for more pragmatic Linux users, Red Hat Enterprise Linux 8.6 has arrived as well.

Hi group. I am in the process of upgrading my desktop with a new motherboard, ram and power supply. I will be running Windows 10 - 64 bit and Linux - 64 bit (still researching which distro to use). This machine will use a Ryzen 3 processor with no internal graphics with 32gb ram and a Samsung 980 1Tb M2 NVME ssd. Any advice on which distro to use would be appreciated.
