# Shell-Scripts
Some Bash scripts I've written.

### Table of Contents

* [colorpalette.sh](#colorpalletesh)
* [dirtybird.sh](#dirtybirdsh)
* [cleanbird.sh](#cleanbirdsh)
* [pcheat.sh](#pcheatsh)
* [colors.sh](#colorssh)
* [mufire.sh](#mufiresh)
* [svgtopng.sh](#svgtopngsh)

# colorpallete.sh
Creates a PNG color palette image with the most common colors contained in another image. Just execute the script via the terminal and you'll be prompted to enter the path to the source image and destination folder. Example:

# dirtybird.sh

This script will recursively traverse all directories under a specified folder and display the names of any dirty files under git control. Folders you want ignored can be added to the `IGNORE` array in the script. You can also set the `SEARCHPATH` variable in the script if you want to hard code a default path.

### Usage:

$   dirtybird.sh        # Checks current directory (and all sub-folders)
                            # You can also set the SEARCHPATH variable in the script to set a default path

$   dirtybird.sh -p     # Checks current directory (and all sub-folders)
                            # If SEARCHPATH variable is set in script, the -p flag overrides it

$   dirtybird.sh /path/to/directory # Checks specified directory (and all sub-folders)

### Dependencies

Dirtybird uses `colors.sh` from this repo to generate colored output. Download it also.

# cleanbird.sh

This script is functionally identical to __dirtybird__, except it does a `git pull` in every directory under source control, instead of a git status check.

# pcheat.sh

Arch Linux package manager cheat sheet.

### Usage

$   pcheat          # Show all commands

$   pcheat -h       # Show help

$   pcheat -s       # Show sync commands

$   pcheat -r       # Show remote package search commands

$   pcheat -q       # Show local search commands

$   pcheat -f       # Show file search commands

$   pcheat -x       # Show remove package commands

$   pcheat -srqfx   # Arguments can be combined

### Dependencies

pcheat uses `colors.sh` from this repo to generate colored output. Download it also.

# colors.sh

Color variables and headings for shell scripts. The script contains two things:

Color variables that allow text in shell scripts to be colorized, and a heading function that outputs a centered heading with a colored background. The background spans the entire width of the terminal. The background color can be specified or it can be random.

### Colorizing Text

To give a text string a color use:

echo -e "${green}This is green text${reset}

echo -e "${bold}${magenta}This is bold magenta text${reset}
    
    # Shorter syntax

echo -e "${pur}This is purple text${r}

echo -e "${b}${mag}This is bold magenta text${r}

__Note:__ Make sure to reset the color at the end of the string.

#### Available Text Colors

COLOR       SHORTCUT
    white       wht
    black       blk
    grey        gry
    red         red
    green       grn
    blue        blu
    cyan        cyn
    yellow      yel
    orange      org
    magenta     mag
    purple      pur

bold        b
    reset       r

### Generating Headings

To generate a heading with a colored background use:

heading <color> "Heading Text"

For a heading with bold text use:

bheading <color> "Heading Text"

For a heading with a randomly selected color use:

heading random "Heading Text"

#### Available Heading Colors

COLOR       SHORTCUT
    random      rnd
    grey        gry
    charcoal    chr
    red         red
    green       grn
    lime        lim
    aquamarine  aqm
    olive       olv
    blue        blu
    sky         sky
    cyan        cyn
    agua        aqa
    goldenrod   gdr
    yellow      yel
    coral       crl
    orange      org
    pink        pnk
    lavender    lav
    magenta     mag
    purple      pur

The above colors can be used to generate your own colored strings. For background colors just prefix "bg" to the color.

echo -e "${bgred}${b}${wht}Red background with bold white text${r}"

# mufire.sh
Multi-file Rename. Allows all the files in a directory to be renamed identically along with an incrementing counter. I wrote the to batch rename images, but it works with any file type.

# svgtopng.sh
SVG to PNG Conversion. This shell script allows easy conversion of SVG images to PNG format in any size or color. The script does not convert individual images, rather all images within any directory you specify. For color replacement, SVG images must be single-color images, with the fill color specified in hex rather than RGB. The background is automatically set to transparent.

## Supported Platforms

I've tested the script on these two platforms:

* __Linux__ (Arch Linux)
* __Mac OS X__ (High Sierra)

## Usage

Just run this script via the terminal using:

$   ./svgtopng.sh

You'll be prompted to:

1. Enter the path to the directory containing the SVG files you wish to convert.
2. Enter the size you want the PNG images to be.
3. Enter the new color in hexadecimal

The script will then replace the SVG fill color, execute the PNG conversion, and place the final images into a new folder.

## Dependencies

* __On Linux__ you must have either __[Inkscape](https://inkscape.org/en/)__ or __[ImageMagick](https://imagemagick.org/)__ installed. The script will automatically detect these packages and use whichever is installed (if both are installed it will default to Inkscape).

* __On Mac OS__ you must have __[ImageMagick](https://imagemagick.org/)__ installed. We recommend installing ImageMagic using __[Homebrew](https://brew.sh/)__. Make sure ImageMagic is installed with the SVG library:

`#  brew install imagemagick -with-librsvg`

## Color Note

In order for this script to change the color of an SVG file, the file  must contain a fill color in hex. For example:

fill="#ffffff"

When the script runs it opens the SVG file and replaces the existing color value with the new color value. If the SVG file does not contain a fill color (or if the color is RGB), the color can not be changed.
