# Linux Scripts
#### Linux utility scripts.
---
## *elf_overview.sh*
### Purpose
Output a simple overview of an ELF executable through the calling `file`, `readelf`, `hd`, `size`, `objdump`, `ldd`, and `strings`. This is easier to run than remember the command-line switches, while some tools (`objdump` and `readelf`) can produce subtly similar outputs.
Another use of *elf_overview.sh* is to verify that files such as PDFs are authentic and not masquerading as executables.
### Usage
```bash
./elf_overview.sh | less
```
---
## *OOM_protect.sh*
### Purpose
Protect a critical application from being killed first by the Linux kernel's OOM Killer.
### Description
1. The critical app on a limited-budget web server might be MySQL.
2. A runaway PHP script, operating through an Apache process, triggers the OOM.
3. But MySQL – using the most memory – is ungracefully killed first, before Apache. The untimely death of MySQL creates database and sales problems.
*OOM_protect.sh* aims to stop the above happening.
(So might the database and web server residing on separate servers.)
### Usage
1. `chmod 700 OOM_protect.sh`
2. set `APP` variable path in the script's *CONFIG* section.
3. `sudo ./OOM_protect.sh`
---
## *icon_save*
### Purpose
Gnome / Nemo desktop icon position restore.
### Description
A Python script to generate a bash script recording desktop icon positions. When desktop icon positions are lost, such as through connecting/disconnecting a second monitor or enacting 'Sort Desktop items by Name', executing the bash script restores the icon positions.
### Usage
Place script in ~/Desktop folder.
#### Create bash script
```bash
python3 icon_save
```
or
```bash
./icon_save
```
#### Restore icons from bash script
+ ensure Desktop 'Auto-arrange' is off
```bash
./icon_restore
```
+ show Desktop
+ press F5
