Flag is a Bash script that simplifies the process of parsing command-line flags in your Bash scripts. It parse flags and convert them to easy-to-use variables in your script.
Flag stands for "Friendly Linux Argument Gatherer" or, if you like recursion, "Flag: Linux Argument Gatherer."
To use flag in your Bash scripts, simply source the script and pass the arguments directly to it, like this:
source /path/to/flag.sh "$@"The script parses both short flags (single-letter flags preceded by a single dash, e.g., -a) and long flags (multi-character flags preceded by two dashes, e.g., --test). Flags without a value are set to 1 (true as boolean). The variables set will be flag_[flag], for example, flag_a for flag -a and flag_test for --test.
