@Fabby People using tools at random....

@Fabby Morning....remote today.

@Fabby well I have some pretty incredible learning resources on the oh long Johnson conspiracy when you are ready to be unplugged from the matrix if .. you want?

anyway what do you do to get around a permission denied error received when trying to execute a .sh script?

@Adam There are two ways around that: 1) execute the script as the user that has the correct permissions, or 2) change the permissions on whatever it is you need to access. Note that changing permissions on random files on the system may have unwanted consequences.

Adam

ok so changing of permissions from within the commands contained in the bash script you want to execute is a never going to happen thing right? @Kusalananda thankyou by the way i probably should have lead with that

i,e one of the commands*

it's just that i enter sudo ./my_sh_bash.sh and i get a permission denied error, it prompts me for authentication which carry out so again there is clearly something fundamental about computing that im just not getting and need to ask the sillys before i move on

Kusalananda

Is the scrip executable?

Adam

sure yes it should be i mean i will check the variable declaration part but the actual doing something on the specified file works fine

executing the commands contained within the .sh directly from the terminal i mean

i don't know now actually maybe not

#!/bin/bash
#Enter ./Extract_ip_addresses_from_txt.sh -f (the txt file you want to extract ip addresses from)
while getopts :f: FLAG; do case $FLAG in

f) # set filename and or path to desired txt file
FILENAME=$OPTARG
;;

\?) # unrecognized option - show help
echo "you are a tool"
exit 0
;;

esac
done

grep -oE '((1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])\.){3}(1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])' $FILENAME>ip_address_list_from_$FILENAME.txt
cat ip_address_list_from_$FILENAME.txt

i was trying have it as such that would enter ./my_script.sh -f="filename.txt
" but yeah i am a little out of my appropriate depth here

but the grep command certainly works in the case of execution from the terminal and having manually specified the filename and path to it

the first part was given to me from an answer in a post i asked in this community or the ubuntu one

ill try to find the link and follow up there

@Jesse_b um yes yes i errr…. i don't know how to private message on this thing... but i totally need heaps of prescriptions "dawg"

@Adam What is the actual error? The error usually includes the name of the command reporting the error, and often a bit more than just "Permission denied".

Adam

sudo: ./Extract_ip_addresses_from_txt.sh: command not found

Kusalananda

@Adam So, not a permission error at all then. Are you spelling the name of the script correctly? And is the script in the current directory?

@Adam Huh?
