Check These Out

uniq without pre-sorting
Reads stdin, and outputs each line only once - without sorting ahead of time. This does use more memory than your system's sort utility.

Rename .JPG to .jpg recursively
This command is useful for renaming a clipart, pic gallery or your photo collection. It will only change the big caps to small ones (on the extension).

Create patch file for two directories

Show contents of all git objects in a git repo
This script finds all git objects and `git cat-file`'s their content. This is really just a helper function to play around with the internals of git repositories. See https://git-scm.com/book/en/v2/Git-Internals-Git-Objects of more info.

Keep track of diff progress
When running a long `diff -r` over folders, this simulates a "verbose" mode where you can see where diff is in the tree. Replace $file with the first part of the path being compared.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Add date stamp to filenames of photos by Sony Xperia camera app
Sony's Xperia camera app creates files without time-stamped names. Thus, after deleting files on the phone, the same names will be reused. When uploading the photos to a cloud storage, this means that files will be overwritten. Running this command after every sync of uploaded photos with the computer prevents this.

Display 6 largest installed RPMs sorted by size (descending)
Low on disk space? Check the largest installed RPMs for delete canditates.

Quickly batch resize images
-geometry (preserves values of height and width given, and aspect ratio). WARNING: While 'resize' creates resized copies of original files, 'mogrify' works on the original files, replacing them. It will overwrite the source files, use with caution, and backup regularly.
