Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today — but the core of science fiction, its essence, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.

good to know!

trurl

Command line tool for URL parsing and manipulation

Video presentation

Examples

Replace the host name of a URL:

$ trurl --url https://curl.se --set host=example.com
https://example.com/

Create a URL by setting components:

$ trurl --set host=example.com --set scheme=ftp
ftp://example.com/

Redirect a URL:

$ trurl --url https://curl.se/we/are.html --redirect here.html
https://curl.se/we/here.html

Change port number:

$ trurl --url https://curl.se/we/../are.html --set port=8080
https://curl.se:8080/are.html

Extract the path from a URL:

$ trurl --url https://curl.se/we/are.html --get '{path}'
/we/are.html

Extract the port from a URL:

$ trurl --url https://curl.se/we/are.html --get '{port}'
443

Append a path segment to a URL:

$ trurl --url https://curl.se/hello --append path=you
https://curl.se/hello/you

Append a query segment to a URL:

$ trurl --url "https://curl.se?name=hello" --append query=search=string
https://curl.se/?name=hello&search=string

Read URLs from stdin:

$ cat urllist.txt | trurl --url-file -
...

Output JSON:

$ trurl "https://fake.host/hello#frag" --set user=::moo:: --json
[
  {
    "url": "https://%3a%3amoo%3a%3a@fake.host/hello#frag",
    "parts": {
      "scheme": "https",
      "user": "::moo::",
      "host": "fake.host",
      "path": "/hello",
      "fragment": "frag"
    }
  }
]

Remove tracking tuples from query:

$ trurl "https://curl.se?search=hey&utm_source=tracker" --trim query="utm_*"
https://curl.se/?search=hey

Show a specific query key value:

$ trurl "https://example.com?a=home&here=now&thisthen" -g '{query:a}'
home

Sort the key/value pairs in the query component:

$ trurl "https://example.com?b=a&c=b&a=c" --sort-query
https://example.com?a=c&b=a&c=b

Work with a query that uses a semicolon separator:

$ trurl "https://curl.se?search=fool;page=5" --trim query="search" --query-separator ";"
https://curl.se?page=5

Accept spaces in the URL path:

$ trurl "https://curl.se/this has space/index.html" --accept-space
https://curl.se/this%20has%20space/index.html

Install

Linux

It's quite easy to compile the C source with GCC:

$ make
cc  -W -Wall -pedantic -g   -c -o trurl.o trurl.c
cc   trurl.o  -lcurl -o trurl

trurl is also available in some Linux distributions. You can try searching for it using the package manager of your preferred distribution.

Windows

1. Download and run Cygwin installer.
2. Follow the instructions provided by the installer. When prompted to select packages, make sure to choose the following: curl, libcurl-devel, libcurl4, make and gcc-core.
3. (optional) Add the Cygwin bin directory to your system PATH variable.
4. Use make, just like on Linux.

Prerequisites

Development files of libcurl (e.g. libcurl4-openssl-dev or
libcurl4-gnutls-dev) are needed for compilation. Requires libcurl version
7.62.0 or newer (the first libcurl to ship the URL parsing API).

trurl also uses CURLUPART_ZONEID added in libcurl 7.81.0 and
curl_url_strerror() added in libcurl 7.80.0

It would certainly be possible to make trurl work with older libcurl versions
if someone wanted to.

Older libcurls

trurl builds with libcurl older than 7.81.0 but will then not work as
good. For all the documented goodness, use a more modern libcurl.

"for begginers" haha, I'd like to see friends of mine try this one out

I was too lazy to write anything remotely as clean as this so I asked Kagi's integration of Mistral Large:

Sure, here's an example of how you could create a systemd timer to automatically renice existing Google Chrome processes.

1. First, create a new service file. You can use any text editor you like, but for this example, we'll use nano:

sudo nano /etc/systemd/system/renice-chrome.service

2. In the service file, add the following lines:

[Unit]
Description=Renice Google Chrome processes

[Service]
Type=oneshot
ExecStart=/bin/bash -c 'for pid in $(pgrep chrome); do ionice -c3 -p $pid; renice 19 -p $pid; done'

This service file defines a new service that runs a bash command to find all Google Chrome processes (using pgrep chrome), and then applies ionice and renice to each process.

3. Save and close the file.

4. Next, create a new timer file:

sudo nano /etc/systemd/system/renice-chrome.timer

5. In the timer file, add the following lines:

[Unit]
Description=Run renice-chrome.service every hour

[Timer]
OnCalendar=hourly
Persistent=true

[Install]
WantedBy=timers.target

This timer file defines a new timer that runs the renice-chrome.service every hour.

6. Save and close the file.

7. Now, enable and start the timer:

sudo systemctl enable renice-chrome.timer
sudo systemctl start renice-chrome.timer

8. You can check the status of the timer with:

sudo systemctl list-timers

This will show you a list of all active timers, including when they're next due to run.

Please note that this will only affect Google Chrome processes that are already running when the timer runs. If you want to also lower the priority of new Google Chrome processes as they're launched, you would need to use a different approach, such as the script I described in my previous answer.

Also, remember to replace chrome with the correct process name if it's different on your system. You can check the process name with pgrep chrome. If it doesn't return anything, try pgrep chromium or pgrep google-chrome.

très bon concept
