Insert command output into current cursor location?

Please don't mind my English since it's not my mother tongue.

Basically, I want to insert some command's output to current line.

Take fzf as an example.

Say my cursor is at the end of ~$ vim , now I press some key and fzf selection menu pops up. After file selection and exiting of fzf, bash current line looks like ~$ vim OUTPUT_STR_HERE.

I heard that When shell-command is executed, the shell sets the READLINE_LINE variable to the contents of the readline line buffer, but bind -x '...' print output to the previous line.

Is this achievable using only bash builtins?

Thanks in advance!

Bash noscript collection

I created a bash noscript collection github repo https://github.com/jothi-prasath/bash-noscripts
currently there is less noscripts.

checkout the repo and contribute your noscripts.

Seeking critique: shell function for reading a password into a variable

This is something I wrote quite a while ago, but I am now wondering whether there's a better way. In particular, I'm not happy with the use of eval. Also, I'm not convinced the use of trap is entirely bullet-proof.

# password <varname>: prompt for and read a password into varname.
password () {
[ -t 0 ] || { echo "$FUNCNAME: stdin is not a tty"; return 2; }

# We use the var=$(foo) && eval construct so that we can run foo
# in a subshell but still get data back from it.
# Since this variable would clash with the user-supplied variable
# name in the eval, we pick something unlikely to be used.
local passwdstr=$(
local ch='' str=''

# Restore echo even if we die
trap 'stty echo' EXIT

# Just read -s is not enough, because characters might
# arrive between calls to read; we must keep echo disabled
# the whole time.
stty -echo
printf "Password: " >&2
while
IFS='' read -r -s -n 1 ch || {
exit 1;
}
# Is the character not a newline?
[[ "$ch" ]]
do
str="$str$ch"
printf "*" >&2
done
printf "%s" "$str"
echo >&2
) && eval "${1-REPLY}="'$passwdstr';
}

need help with xdg-open noscript

Hello I'm a Linux noob trying to get my all my application to work on Linux. I finally got Unreal Engine 5 to work on Ubuntu, but I'm having trouble getting a bash noscript to open Unreal Editor and would like some help.

\#! /bin/bash

xdg-open "../UnrealEngine/Engine/Binaries/Linux/UnrealEditor"

It will open the file location if I don't put "UnrealEditor" but when I do it gives me a

:Failed to find default application for content type ‘application/x-executable’

any advice would help

showing system stats during startup (novice showcase)

Hi. I have been tinkering around with bash and have the following setup to email me some stats during startup -

## cat /etc/systemd/system/customstartup.service
[Unit]
Denoscription=Notify that system has booted.
Wants=network-online.target
After=network-online.target

[Service]
Type=simple
ExecStart=/bin/bash /home/user/bin/startupbootstrap.sh

Install
WantedBy=multi-user.target

and here's the noscript

## cat /home/user/bin/startupbootstrap.sh

#!/usr/bin/env bash

hostname=$(hostname -s)

lastreboot=$(command last -xF reboot | head -1 | awk {'print $5, $6, $7, $8'})
lastshutdown=$(command last -xF shutdown | head -1 | awk {'print $5, $6, $7, $8'})
uptime=$(uptime -p)
lastboot=$(who -b) # display time of last system boot

avgload=$(grep 'cpu ' /proc/stat | awk '{cpuusage=($2+$4)*100/($2+$4+$5)} END {print cpuusage "%"}')
cpuusage=$(top -n 1 | head -n 3 | tail -n 1 | awk '{print $2 + $4}')

day=`date +"%F %T"`
printf "[ %s ] %s\n\n" "$day" "$hostname"
printf "System powered ON at %s. " "$lastreboot"
printf " %s \n" "$uptime"
printf "Last successful shutdown at %s \n\n" "$lastshutdown"

printf " %s Avg. CPU Load\n" "$avgload"
printf "[ %s ] CPU Usage\n" "$cpuusage"


Any way I can improvise the noscript ? Thanks in advance.

Help with understanding awk code

Hey guys,

I'm quite new to bash still and I found a piece of code online which removes new lines from a FASTA text file but I was hoping someone could help me break it down and understand how it's working. Here is the code:

awk '/^>/ {printf("%s%s\t",(N>0?"\n":""),$0);N++;next;} {printf("%s",$0);} END {printf("\n");}'

Thanks in advance :)

Need help with inner loop from a while read with multiple values

SRC FILE:

hostname WWN1 WWN2 WWN3 WWN4
hostname WWN1 WWN2 WWN3 WWN4

....

&#x200B;

Hello,

I am looking to use an inner loop on the WWN values in my bash noscript.

This is what I have thus far, but can't seem to get the WWN values into the inner loop, any ideas what I am doing wrong?

&#x200B;

#!/usr/bin/env bash

while read host wwn1 wwn2 wwn3 wwn4; do
echo $host
for i in {1..4}; do #THIS DOES NOT WORK
ggrep -A18 -E $wwn$i $host.storage_check.txt > $host.$wwn$i.txt
done
done

&#x200B;

this doesn't work because its the 1..4 being used and not the WWN1-4

I want to read in the 5 values per line and then use them in the inner loop. Is it possible?

If I do this line by line, yes it works, but I want it cleaner in a loop if possible.

&#x200B;

ggrep -A18 -E $wwn1 $host.storage_check.txt > $host.$wwn1.txt
ggrep -A18 -E $wwn2 $host.storage_check.txt > $host.$wwn2.txt
ggrep -A18 -E $wwn3 $host.storage_check.txt > $host.$wwn3.txt
ggrep -A18 -E $wwn4 $host.storage_check.txt > $host.$wwn4.txt

&#x200B;

I just cant seem to find what I am looking for to do this.

best way to deal with unexpected operator when user inputs enter instead of a letter?

context: user is given two valid options to choose from

read var
while [ $var != a \] && [ $var != z \]
do
printf "Not a valid option. Enter again\\n"
read var
done


but if the user presses the enter key, then
[: !=: unexpected operator
same thing happens when the user is supposed to enter a number but enters a letter instead and vice versa

is 2>/dev/null the best solution?

How to write a mounted shared path

I haven't touched bash or cbash in years and today i installed a ubuntu VM client on a windows OS.
The VM shares a folder, and i'm planning to convert a few noscripts into bash (or whatever) which i previously ran in windows batch files.

The question i have is how do i write the path?
The path in windows might be e:/shared
I think the folder in ubuntu is /mnt/hgfs/shared

Is /mnt/hgfs/shared the path i use in a bash noscript file?

Eg., Delete pdfs in a subfolder might be something like "rm /mnt/hgfs/shared/no-more-pdfs/*.pdf"?

Thx

Can't get archiving backup noscript to work

Following a readout of a noscript in the 'Linux Command Line and Shell Script BIBLE (4th Ed.)', and it doesn't seem to archive the directories specified in the files-to-backup.txt file; rather, I get a 45B 'archive<today's-date>.tar.gz' file (in the correct periodic directory, at least) that's completely empty.

It does use an interesting method of building the $file_list variable, though:

Now, I have modified the noscript, adding the 'prune\backups()' function, but something doesn't quite seem right though, and I can't put my finger on what it is. Can anyone see either where I've screwed up, or if it's just something with the noscript itself?
