Random code snippetsPosted: 04.06.13
Random but oddly useful code snippets that I use from time to time.
- To display images as a preview and a clickable link in HTML:
<a href="http://dl.dropbox.com/u/54881717/screenshots/DSL/dsl2.jpg"><img alt="DSL Creeper BG" src="http://dl.dropbox.com/u/54881717/screenshots/DSL/dsl2.jpg" width="400" height="300" /></a>
Width and height need to be manually set.
- Main function for a “do something to every file (including those in subdirectories) within specified folder”, written in bash:
#!/bin/sh echo "Enter target dir" read -p ">" workdir while [ ! -d $workdir ]; do echo "That directory does not exist. Please enter target dir" read workdir done cd $workdir for i in $(find -type f -name '*'); do echo "Ho." > $i done
