Vim users:

Do you use vi mode in your shell (bash, zsh, fish, etc.), the default bash mode, or something else?

ICYMI: Bash 5.3 has been released with what its developers describe as 'significant' new features

https://www.omgubuntu.co.uk/2025/07/bash-5-3-new-features?v1

Bash 5.3 is Here!
After 3 years, the beloved GNU shell gets a major upgrade — smarter command substitution, C23 support, new sorting options & more.
Ready to upgrade your shell?
#gnu
#linux
#bash
#sh

Why did it take me two decades to do this?

```
function mkcd() { mkdir "$@" ; cd "$@" ; }
```
#bash #shell

#ripgrep replacement in #bash with #GNU #grep.

ripgrepgeneric: da, wo es kein ripgrep gibt

zum beispiel auf alten, zu migrierenden, servern. auf denen es wohl noch alte configs zu durchforsten, aber keine attraktive möglichkeit ripgrep nachzuinstallieren, gibt.

da sucht man, in welcher datei das suchwort drinsteht und wenn ja, an welcher stelle.

dieser zweizeiler mit variablenübernahme wird durch das script komftebel™ vertreten.

This video was helpful in getting me started on writing my own bash script to automate the process of creating ZFS snapshots and doing backups to my home server.

[Video starts at 9:45 where the scripting begins]...

Hi everyone! I recently released 3 blog posts!
All of them are writeups on CTFs where I make some scripts and tools in bash and golang!

I'll leave you the link of the blog posts and if you have any suggestions or interact with me, don't hesitate to comment or DM me!

I hope you all can enjoy reading them!

In the helpful shell functions department:

(Requires bc to be installed)

load() {
    local load=$(uptime |sed -E "s/^.*load averages?: //; s/,.*$//")
    local uname="$(uname)"
    local cpus
    if [[ $1 == -q ]]; then
        echo "$load"
    elif [[ $1 == -i ]]; then
        echo "$load + 0.5" |bc -l |cut -f1 -d.
    else
        case "$uname" in
            Linux)  cpus=$(grep -c ^processor /proc/cpuinfo);;
            *BSD)   cpus=$(sysctl hw.ncpu |tr -dc "0-9\n");;
            *)      warn "load(): assuming 1 cpu, don't know how to get the number in \"$uname\""
                    cpus=1;;
        esac
        local loadPerCPU=$(echo "scale=3; $load / $cpus" |bc -l |sed 's/^\./0./')
        echo "$load ($loadPerCPU per processor ($cpus))"
    fi
}

I wrote a script - convert a directory of JPEG files to a single PDF document. Can someone fix or improve something? #commandline #bash #scripts

#Poll: Curious about people's attitudes towards shell scripting.

Two part question:

1. Are you a DEVeloper (or working in a development-heavy role), OTHER-IT worker (such as a sysadmin, architect, anything in a non-development-heavy role), or NON-IT (accountant, doctor, whatever)
2. Do you HATE shell scripting, are you INDIFferent towards (or ignorant of) shell scripting, or do you LOVE it?

Seit 25 Jahren arbeite ich mit Linux und ja – Windows ist nicht das OS, das ich freiwillig nutzen möchte. Aber dieses ewige OS-Bashing erinnert eher an einen Streit auf dem Pausenhof als an einen erwachsenen Diskurs. Wer Spaß an seinem System hat, soll es nutzen. Linux ist solide, manchmal sogar elegant – aber kein Heilsversprechen. Und das muss es auch nicht sein.

Die Welt dreht sich weiter – ob mit #Bash oder #PowerShell spielt längst nicht mehr die Hauptrolle.

Unintended execution of subshell commands and substitutions while installing script with here document #bash #scripts

What does this command do? XML_FILE=$(awk -F: '$1 ~ /^XML$/{ printf("%s",$2) }' "${res_file}") #commandline #bash #scripts #textprocessing #awk

How would you solve the following use case when #bash #scripting ?

Given a text file and need to insert a line somewhere specific.
Extra challenging: Assume some lines are identical.

This might be worth sharing with @b0rk 's audience.

I'll share a solution I just used at work in the first comment; worth adding to ones #cheatsheet!
