# Linux | Quickstarts
Linux Quickstarts... Some of my past notes.
Contains command lists with some example of usage. Also this repo includes useful links related to Linux.
## Command lists
### Multimedia
#### Images
- `convert` - convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.
- `mogrify` - resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. Mogrify overwrites the original image file, whereas, convert-im6.q16(1) writes to a different image file.
- `find . -name "*.jpg" -exec mogrify -format png {} \;` - Modify all the JPGs to PNG.
## Job Control
For running a process in the background.
### Basic commands:
- `Ctrl-C`: Kill the process running in the foreground by sending the signal SIGINT
- `Ctrl-Z`: Suspend the process running in the foreground by sending the signal SIGTSTP
- [`jobs`](https://www.man7.org/linux/man-pages/man1/jobs.1p.html): Display a list of the jobs with their status
- [`fg`](https://www.man7.org/linux/man-pages/man1/fg.1p.html): Move a background job into the foreground
- [`bg`](https://www.man7.org/linux/man-pages/man1/bg.1p.html): Resume suspended jobs by running them as background jobs
### The `&` Operator
When used at the end of a command it will run the process in a subshell (in the background). It also does not wait for the process to end it returns a 0 status.
When a job runs in the background, its output is still displayed in the terminal. This occurs because the background process initiated by the `&` operator inherits the shell's *stdout* and *stderr*.
#### The *SIGHUP* Signal

### The `disown` Command
