jesselawson / remove-files-containing-string-in-filename.ps1

Created April 19, 2016 14:35

Powershell - Remove all files where filename contains string

jesselawson / stage-files-from-index-file.ps1

Created February 2, 2017 19:19

We worked with a 3rd party vendor (ViaTRON) to scan a bunch of images. They created a text file with identifying information that included the location of the associated images, in incremental, integer form. This script was used to pull out the relevant fields and then stage the files to be uploaded to ImageNow.

	# This file will read through the index files (*.txt) and
	# copy/rename the files appropriately so that they're ready for upload to ImageNow

	# Example index file:
	# "SID","LAST NAME","FIRST NAME","DOB","DOCTYPE","IMAGE"
	# "234234","Lastname","Firstname","1/15/1986","STUDENT APPLICATION","E:\APPLICATIONS\1.TIF"
	# "345345","Johnson","Bob","8/25/1986","GRADE WAIVER","E:\APPLICATIONS\2.TIF"
	# "456456","Doe","Jane","1/15/1986","STUDENT APPLICATION","E:\APPLICATIONS\3.TIF"

	# Note that the index file is in CSV form.

jesselawson / bad_string_literals.c

Created April 23, 2019 20:13

An example of how string literals persist in stack memory. This is NOT how you do dynamic strings!

	#include <stdio.h>
	#include <string.h>

	int main(void) {
	char* full_name = "Jesse Lawson";
	char* ptr = full_name;
	printf("newptr: %p\n", ptr);
	full_name = "Jesse Happy Bubble Fun Club Lawson";
	ptr = full_name;
	printf("newptr: %p\n", ptr);

jesselawson / dynamic_strings_example.c

Created April 24, 2019 15:50

An example of how you can use malloc(), realloc(), and free() to create dynamic strings.

	#include <stdio.h>
	#include <string.h>
	#include <stdlib.h>

	int main(void) {
	// sizeof(char) is always 1, but we have it here
	// for instructional purposes
	char* full_name = malloc(sizeof(char)*strlen("Jesse Lawson")+1);

	strcpy(full_name, "Jesse Lawson");
