Select files with multiple different file extensions
Select all HTML files and PHP Scripts and XML files? Yep.


# *.{a,b,c,d}
ls -alh *.{md,json,html,xml} # list all files ending in given extensions
find . -type f *.{html,xml,php} # find all files ending in given extensions
find . -type f *.{html,xml,php} -exec rm -rf {} \; # find and delete all files ending in given extensions

Find/List files

find . -type f *.{html,xml,php}

will find all (*) files (-type f) in the current directory (.) ending in .html, .xml or .php. You can add as many comma seperated values as you want, no spaces in between.

One case scenario when this has been useful is when i had to delete hacked files from a WordPress wp-content/uploads directory. It contained files with executable PHP code, spam pages ending in .html, XML scripts and the like left behind by the hacker. (Usually, the WordPress uploads directory only contains images or uploaded files - PDFs and such, but not scripts. Some plugins may use the Uploads directory, but that's not our concern right now, moving on..).

ls -alh *.{md,json,html,xml}

find works recursively while ls will only list files in the current directory (and not it's sub-dirs)

Delete files

find . -type f *.{html,xml,php} -exec rm -rf {} \;
