mshafiee / create-certificate-stack.sh

Created February 13, 2023 20:59

This is a bash script that creates a CloudFormation stack for a public certificate with DNS validation, based on input parameters provided as command line flags.

	#!/bin/bash
	# This is a bash script that creates a CloudFormation stack for a public certificate with DNS validation,
	# based on input parameters provided as command line flags.
	# The script starts by defining the print_help function that displays the usage information for the script,
	# along with the available command line flags.
	# Next, the script uses the getopts command to parse the command line flags and store their values in variables
	# (stack_name, csv_file, and domain_name). If any of the required flags are missing, the script will display
	# an error message and exit.
	# The script then reads the contents of the CSV file into a bash array (subject_alternative_names), which
	# will be used to specify the SubjectAlternativeNames for the certificate.

mshafiee / resetBranch.sh

Created February 4, 2023 15:14

This bash script will check if a branch named BRANCH_NAME exists in the Git repository. If it exists, it will checkout to that branch and reset the branch to the previous commit, discarding all previous commits except the last one. It will then rename the latest commit to COMMIT_NAME and push the rewritten branch to the remote repository. Finall…

	# discarding all previous commits except the last one. It will then rename the latest

mshafiee / linux_read_conjugations_sein.sh

Last active January 23, 2023 17:07

	# This script is a command line tool that reads German conjugations of the verb "sein" (to be)
	# in the present tense using Festival TTS engine on Linux. The script declares an array of strings,
	# each string containing a conjugation of the verb "sein" for a different personal pronoun.
	# Then, it uses an infinite while loop to iterate over the array, reading each conjugation 60 times
	# with a sleep of 1 second in between each reading. The script uses the echo "$i" \| festival --tts -voice de
	# command to read the current string in the array, where -voice de option is added to the festival --tts command,
	# which causes the TTS engine to use a German voice. The script is useful for language learners who want to
	# practice the conjugations of the verb "sein" in the present tense on Linux.
	# How to install festival:
	# sudo apt-get install festival
