Quick HTML image gallery

My take on the original: even though I like the other's use of -exec echo, sed just feels more natural. This should also be slightly easier to improve.

I expanded this into a script as an exercise, which took about 35 minutes (had to look up some docs): http://bitbucket.org/kniht/nonsense/src/7c1b46488dfc/commandlinefu/quick_image_gallery.py

Quick HTML image gallery from folder contents

Setting: You have a lot of jpg files in a directory.

Maybe your public_html folder which is readable on the net because of Apache's mod_userdir. All those files from the current folder will be dropped into a file called gallery.html as image tags that can be viewed within a web browser locally or or over the Internet.

Original:

find . -iname "*.jpg" -exec echo "<img src=\"{}\">" >> gallery.html \;

Quick HTML image gallery from folder contents with Perl

This includes a title attribute so you can see the file name by hovering over an image. Also will hoover up any image format - jpg, gif and png.

What others think

kniht, shouldn't that end with >> gallery.html so that each invocation appends to the initial result instead of overwriting it?

Comment by unixmonkey10648 150 weeks and 4 days ago

@unixmonkey10648: The redirection applies to all of the output of sed, which is the output of everything piped to it from find (after substitution) -- there is only one invocation. If you wanted to combine multiple directories into one gallery.html, you could do that by changing "find ." to "find some/a other/b third-directory". If you really did want to append to gallery.html, you could do that, of course, it would just be unusual.

Also, I kept the original's *.jpg mask, but you could change -iname to -iregex to grab multiple image types.
