WordPress Plugin to embed Gitea Repositories

I ported the WordPress plugin providing shortcodes for embedding Gitlab projects into posts and pages to a Gitea version.

Below is a usage example, displaying the latest 3 commits and the latest release (if any) from repository „linuxfoo-gitea“ on my Gitea instance:

[gitea-show-project url="https://tk-sls.de/git" project_owner=tk-sls.de project_repo=linuxfoo-gitea max=3 releases=latest]
Gitea project linuxfoo-giteaLast 3 commits: by root: 35962433 correct json pat to commit message by root: fccb7dd5 correct message formatting by root: 19f52bfb correct class namesLatest release: v1.0.0

PiKVM on an OrangePi Zero 2

The OrangePi Zero 2 H616/1GByte is capable of running PiKVM. I find this an interesting development, because if i only want the KVM functionality, a full-blown Raspberry Pi 4 with all its CPU resources, multiple Gigabytes of RAM and peripheral devices seems somewhat of an overkill. I am aware that the latest official PiKVM, the V4Plus uses a Raspberry Pi Compute Module with 2 GB RAM, but mine is still smaller. 🙂

Print all indented Lines following a non-indented Line

Some configuration and output text formats contain sections like the following:

   value 3

In this article, two scripts are presented that print all consecutive indented lines that follow a non-indented line that matches a search pattern given by a regular expression.

This means, given the single argument foo and the standard input above, the scripts should

  • determine the line that matches foo and
  • print the following two lines, but no other lines.

Also, the indentation of the printed lines should be removed.

A simple GUI for basic Package Management with Apt

The tool presented here, „Simple Apt Update“ (simple-apt-update) is nothing more than a front-end to the non-interactive execution of apt-get update|full-upgrade and apt list --upgradeable. It can look like this:

Maintaining Multi-Line „stat“ Formats using Bourne Again Shell

The stat command from GNU core utilities features not only a --format FORMAT option but also a --printf FORMAT one, the difference being that the latter allows for backslash escapes such as \n.

This allows for custom per-file report formats containing newlines, for example:

stat --printf 'Name: %n\nSize: %s Bytes\n' /etc/passwd

If the format string becomes more complex, the command line soon becomes unwieldy, such as:

stat --printf 'Name: %n\nOwner ID: %u\nSize: %s Bytes\nLast accessed: %x\n' /etc/passwd

Make a Bourne Again Shell Script Log its Output to a File

The Bourne Again Shell script presented in this article demonstrates techniques related to capturing and logging output (standard output and standard error stream) of a script into a log file while also delivering it to the regular output destinations (for example the terminal or whatever the caller has chosen to redirect to). Some questions are addressed:

  • How to „clone“ standard output and standard error stream of a shell script to a single log file?
  • Are the messages from both streams interleaved into a single file in the appropriate order?
  • Can a script perform output cloning for some portions of its procedure while skipping it for others?
  • Are there specific requirements for output that is to be cloned to a file?
  • Are there best practices when a script modifies its own output redirections?

The example provided below has been tested on GNU/Linux using GNU „bash“ version 5 and „tee“ version 8.32 from GNU coreutils. It uses the Bash-only feature of process substitution. An implementation in POSIX Shell (possibly using only POSIX tools) would be more difficult.

Using sed or awk to ensure a specific last Line in a Text

Given a file containing bytes of text with lines separated by the newline character (\n), one of these lines can be said to be „the last line of the file“; it is a sequence of bytes occurring in the file, for which holds:

  • The sequence contains no newline character, and
  • the sequence is followed by at most one newline character and no other bytes.

The task at hand is, using shell utilities, to write a procedure that makes sure that a given file contains a last line that contains a desired sequence of text characters.
