Gnu-linux-shell-scripting is a foundation for shell scripting in GNU/Linux.

It is made up of the following four types of solutions:

1. Scripts
2. Functions scripts
3. One-liners
4. Aliases

Here is a list of all the categories with a few examples in each:

• Generic RDBMS utility functions for a MySQL database
• Check if a PostgreSQL database exists.

• Rename all files matching a name recursively.
• Get the size in megabytes of one or more files and/or directories.

• List all processes owned by the current user.
• Print the target architecture of the current operating system.

• Check if the primary wireless local area network device interface is soft blocked.
• Get the vendor name of the CPU.

• Execute a command in the background.
• Remove the last N entries from the bash history.

• Get the ID of the active window.
• Get the class of a window by ID.

• Watch the X and Y screen tap positions of an Android device.
• Mount and unmount an MTP device.

• Bash array utilities
• Bash date and time utilities

• Replace all occurrences of a string recursively.

• Count the number of characters in a string.

• Convert a hexidecimal number to decimal.

Gnu-linux-shell-scripting has an extension repository for solutions consisting of more than one file.

All the solutions in this repository follow this standard guideline.
