Check These Out

Kill any process with one command using program name
This will kill all. e.g. killall firefox

list files recursively by size

Use default value if unassigned
Will use variable value (for variable $my_dir, in this case), an assign a default value if there is none.

Isolate file name from full path/find output
Quick method of isolating filenames from a full path using expansion. Much quicker than using "basename"

Image to color palette generator
Extract a color palette from a image useful for designers. Example usage: $extract-palette myawesomeimage.jpg 4 Where the first argument is the image you want to extract a palette from. The second argument is the number of colors you want. It may be the case where you want to change the search space. In that case, change the -resize argument to a bigger or smaller result. See the ImageMagick documentation for the -resize argument.

Rsync using SSH and outputing results to a text file
--delete will delete copies on remote to match local if deleted on local --stats will output the results -z zip -a archive -A preserve ACL -x don't cross filesystem boundaries -h human readable -e specify the remote shell to use

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Btrfs: Find file names with checksum errors
Btrfs reports the inode numbers of files with failed checksums. Use `find` to lookup the file names of those inodes. The files may need to be deleted and replaced with backups.
