This repository contains some (linux) scripts I am using to simplify my daily work (call it what you want), modify applications to make them look more estatic or just because I can and I have too much time.

## Firefox Icon Fix
|
|
||||||
|
|
||||||
This changes the firefox icon to whatever image you want.
|
|
||||||
The [default image](firefox-icon-fix.png) is Senko from the anime 'The Helpful Fox Senko-san'.
|
|
||||||
If you want to change the image, just replace 'firefox-icon-fix.png' with the image you want. Your image **has to be** named 'firefox-icon-fix.png' too.
|
|
||||||
|
|
||||||
Since the script uses softlinks to reduce space, make sure you never delete or change this directory if it is on your disk and you have fixed the icons with the script.
|
|
||||||
|
|
||||||
**NOTE:**
|
|
||||||
For better usage make the script executable first:
|
|
||||||
```console
|
|
||||||
$ chmod +x firefox-icon-fix.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Usage
|
|
||||||
|
|
||||||
Fix icons:
|
|
||||||
```console
|
|
||||||
$ ./firefox-icon-fix.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
Unfix icons (restore the real ones):
|
|
||||||
```console
|
|
||||||
$ ./firefox-icon-fix.sh unfix
|
|
||||||
```
|
|
||||||
|
|
||||||
Re-fix icons after firefox update (the icons are sadly getting resetted after every firefox update):
|
|
||||||
```console
|
|
||||||
$ ./firefox-icon-fix.sh --overwrite
|
|
||||||
```

## Hashify Filename
|
|
||||||
|
|
||||||
This little script renames given files to its [MD5](https://en.wikipedia.org/wiki/MD5) hashsum. File extension won't be changed.
|
|
||||||
This allows duplicate files in the same directory to be easily detected and merged / overwritten.
|
|
||||||
|
|
||||||
This script is just a fork of [randomize-filename](../randomize-filename).
|
|
||||||
|
|
||||||
|
|
||||||
#### Arguments
|
|
||||||
|
|
||||||
The can take one extra argument
|
|
||||||
|
|
||||||
`-r` - recursive: If any directory where given while calling this command, all files in it will be renamed recursively.
|
|
||||||
|
|
||||||
#### Usage
|
|
||||||
|
|
||||||
```
|
|
||||||
$ hashify-filename.sh -r .
|
|
||||||

## Java beautifier
|
|
||||||
|
|
||||||
Makes java code look like it should.
|
|
||||||
|
|
||||||
#### Usage
|
|
||||||
|
|
||||||
```
|
|
||||||
./java-beautifier.py <a java file>
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Example
|
|
||||||
|
|
||||||
1. Create a `Main.java` with the following content:
|
|
||||||
```java
|
|
||||||
public class Main {
|
|
||||||
|
|
||||||
public static void main(String[] args) {
|
|
||||||
System.out.println("I'm so beautiful");
|
|
||||||
}
|
|
||||||
|
|
||||||
public static class UnnecessarySubClass {
|
|
||||||
public static void unnecessaryVoid() {
|
|
||||||
System.out.println("Hello, i'm unnecessary");
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Beautify the file: `./java-beautifier.py Main.java`
|
|
||||||
|
|
||||||
3. Look at the beautiful output:
|
|
||||||
```java
|
|
||||||
public class Main {
|
|
||||||
public static void main(String[] args) {
|
|
||||||
System.out.println("I'm so beautiful"); }
|
|
||||||
public static class UnnecessarySubClass {
|
|
||||||
public static void unnecessaryVoid() {
|
|
||||||
System.out.println("Hello, i'm unnecessary"); }}}
|
|
||||||

## Randomize Filename
|
|
||||||
|
|
||||||
With this little script you can randomize the names of given files. File extension won't be changed.
|
|
||||||
|
|
||||||
|
|
||||||
#### Arguments
|
|
||||||
|
|
||||||
The file takes several arguments
|
|
||||||
|
|
||||||
`-r` - recursive: If any directory where given while calling this command, all files in it will be renamed recursively.
|
|
||||||
|
|
||||||
`-a` - all (the name is a little misleading): Normally directories are not renamed, but with this argument they will.
|
|
||||||
|
|
||||||
`-l LENGHT` - lenght: The lenght of the randomized filenames (default is 16). Replace `LENGHT` with the lenght the randomized names should have.
|
|
||||||
|
|
||||||
#### Usage
|
|
||||||
|
|
||||||
```
|
|
||||||
$ randomize-filename.sh -r .
|
|
||||||
